text: Unlike the United States Congress, there is no "lame duck" session of Parliament in most Commonwealth countries between the general election and swearing in of elected officials. In almost all cases, the outgoing prime minister or premier hands over power directly to their designated successor after a leadership contest or general election. Usually, when the leader of a ruling party steps down, they also relinquish their caucus leadership role at around the same time, so there is no need for an interim caucus leader. After an election retiring/defeated members of United States Congress do continue to wield their full authority until their term ends, by contrast the power of outgoing Canadian parliamentarians is limited. Instead the departing prime minister or premier and cabinet ministers that were members of the now dissolved parliament will serve in an "acting" or "caretaker" capacity (i.e. not being able to make important appointments nor policy declarations) until the new parliament convenes; in one example when Sir Charles Tupper attempted to make appointments after losing the 1896 Canadian election the Governor General refused to act on this.

text: A notable exception to the above is the transition between William Lyon Mackenzie King and Louis St. Laurent, making it perhaps the only lame duck example in Canadian federal politics. After resigning the leadership of the Liberals, King became parliamentary leader and continued as Prime Minister of Canada for some months following the leadership election of his successor, St. Laurent, who became party leader but continued as a member of King's cabinet during this time.

text: While Pierre Trudeau retired from politics in 1984, he directly handed power over to John Turner after the leadership contest. However, Trudeau recommended that Governor General Jeanne Sauvé appoint over 200 Liberals to well-paying patronage positions, including Senators, judges, and executives on various governmental and crown corporation boards, widely seen as a way to offer "plum jobs" to loyal party members. These appointments generated a severe backlash across the spectrum. Turner had the right to recommend that the appointments be cancelled: advice that Sauvé would have been required to follow by constitutional convention. However, he let them stand and made a further 70 appointments himself. Turner refused to produce a written agreement he had made with Trudeau before taking office, documenting a secret deal that saw Trudeau step down early. This is seen by many as Trudeau attempting to exercise some lame duck influence before resigning as Prime Minister.

text: In 1984, a constitutional crisis arose when the outgoing "lame duck" Prime Minister Robert Muldoon refused to follow the wishes of a new incoming government led by David Lange. This was the only time in New Zealand where a "lame duck" Prime Minister did not follow the wishes of the incoming government.

text: Like many parliamentary systems, but unlike countries such as the United States that build in a transition period between elections and the taking of office by their winners, the UK does not have lame ducks in the sense of politicians holding office for a substantial delay after a successor has been elected.


title: Lame duck (politics)

text: Following general elections where a party wins a clear majority in the House of Commons, the identity of the new prime minister is immediately apparent and they are usually appointed the following morning, minutes after their predecessor resigns the office, at back-to-back meetings with the monarch. In the case of a hung parliament where the election is followed by negotiations to form a coalition, or an attempt by the leader of the largest party to lead a minority government, a new prime minister may not be appointed for a few days. In the 2010 election for example, which was held on May 6, Gordon Brown's Labour Party lost its majority in the Commons, but Brown remained caretaker prime minister until May 11, resigning when it became clear that the Conservative Party (which held a plurality) had reached a coalition agreement with the Liberal Democrats, whereupon the Conservative leader David Cameron was appointed prime minister.


title: Lame duck (politics)

text: Members of parliament cease to be such when parliament is dissolved for a general election, and cannot describe themselves as "John Smith MP" during the election campaign. Government ministers however, as part of the executive, continue to hold office unless and until new ministers are appointed after the election.


title: Lame duck (politics)

text: An example of a lame-duck period in the informal sense is the last two years of the premiership of Tony Blair, who before the 2005 United Kingdom general election announced that he would not serve another full term before standing down. However, the fact that Blair's Labour Party was returned with a substantially reduced majority and that Gordon Brown (who was correctly believed to be Blair's successor) had played a leading part in the election campaign, aroused considerable speculation about Blair's future as party leader and prime minister.


title: Lame duck (politics)

text: In U.S. politics, the period between (presidential and congressional) elections in November and the inauguration of officials early in the following year is commonly called the "lame duck period". A president is a lame duck after a successor has been elected, during which time the outgoing president and president-elect usually embark on a transition of power.


title: Lame duck (politics)

text: Until 1933, inaugurations occurred on March 4. Congress usually had two sessions, the second of which was usually held from the December after the election of the next Congress until March. This session was commonly called the "lame duck session". Criticism of this process led to the passage of the 20th Amendment in 1933, which moved the beginning of the new Congress to January 3 and the inauguration of the president to January 20, thus shortening the lame duck period.


title: Lame duck (politics)

text: A president elected to a second term is sometimes seen as a lame duck from early in the second term, since term limits prevent them from contesting re-election four years later. However, not personally having to face the electorate again makes a second-term president more powerful than they were in their first term as they are thus freer to take politically unpopular actions. However, this comes with caveats; as the de facto leader of their political party, the president's actions affect how the party performs in the midterm elections two years into the second term, and, to some extent, the success of that party's nominee in the next presidential election four years in the future. For these reasons, it can be argued that a president in their second term is not a lame duck at all.


title: Lame duck (politics)

text: In his farewell speech from the office of president in January 2017, Barack Obama jokingly quipped, "You can tell that I'm a lame duck because nobody's following instructions" when the cheering and applause from the crowd prevented him from commencing his speech.

text: On February 11, 2013, when Pope Benedict XVI announced that he was resigning within 17 days, he was called a "lame duck pope" by some media outlets. Also, due to Pope John Paul II's long and debilitating illness, some journalists (such as "Time"s Jeff Israely) described the final years of his reign as a lame duck papacy.


title: Lame duck (politics)

text: The discontent with the ruling United Socialist Party of Venezuela saw the opposition being elected to hold the majority in the National Assembly of Venezuela for the first time since 1999 following the 2015 parliamentary election. As a result of that election, the lame-duck National Assembly consisting of United Socialist officials filled the Supreme Tribunal (supreme court) with allies. Into early 2016, the Supreme Tribunal alleged that voting irregularities occurred in the parliamentary elections and stripped four Assembly members of their seats, preventing an opposition supermajority in the National Assembly which would be able to challenge President Maduro. The Assembly nevertheless swore in the members in question, in response to which the Supreme Court ruled that the Assembly was in contempt of court and in violation of the constitutional order. The Supreme Tribunal then began to approve multiple actions performed by Maduro and granted him more powers and later stripped the National Assembly of legislative powers, and took those powers for itself; which meant that the Supreme Tribunal might have been able to create laws, causing the 2017 constitutional crisis.

text: In sports usage, a coach or general manager in the final year of their contract without a forthcoming contract extension is often described as a lame duck.


title: Lame duck (politics)

text: However, if a team is on track to miss the playoffs, a coach or general manager can be regarded as a lame duck even if they are under multiyear contracts, if they are expected to be fired shortly before or once the season ends. Often taking the blame as the team is out of contention for the postseason, the coach or/and general manager is seen as a poor fit or otherwise does not relate well with others – players and other coaches, the media, his superiors and so forth – and a change in leadership is apparently forthcoming or desired. Often, there will be rumors of a coach and/or manager departure – often by dismissal or forced resignation (also known as "by mutual consent") – with said rumors often beginning several games before the end of the season. Dismissal of the coach and/or manager once the team is eliminated from reaching the postseason, rather than waiting for the conclusion of the season, does cut short their "lame duck" status and clears the way for new hires. In that case, an interim coach and/or interim manager will be appointed to see out the remainder of the season, though their predecessors may still remain on the club payroll as a "special advisor" until their contracts expires.

text: Especially in the United Kingdom, a "lame duck company" is one that is in such financial difficulty that it is not worth investing in, or is unworthy of government support.


title: Overhead (business)

text: In business, overhead or overhead expense refers to an ongoing expense of operating a business. Overheads are the expenditure which cannot be conveniently traced to or identified with any particular revenue unit, unlike operating expenses such as raw material and labor. Therefore, overheads cannot be immediately associated with the products or services being offered, thus do not directly generate profits. However, overheads are still vital to business operations as they provide critical support for the business to carry out profit making activities. For example, overhead costs such as the rent for a factory allows workers to manufacture products which can then be sold for a profit. Such expenses are incurred for output generally and not for particular work order; e.g., wages paid to watch and ward staff, heating and lighting expenses of factory, etc. Overheads are also a very important cost element along with direct materials and direct labor.


title: Overhead (business)

text: Overhead expenses are all costs on the income statement except for direct labor, direct materials, and direct expenses. Overhead expenses include accounting fees, advertising, insurance, interest, legal fees, labor burden, rent, repairs, supplies, taxes, telephone bills, travel expenditures, and utilities.


title: Overhead (business)

text: There are essentially two types of business overheads: administrative overheads and manufacturing overheads.


title: Overhead (business)

text: Administrative overheads include items such as utilities, strategic planning, and various supporting functions. These costs are treated as overheads due to the fact that they aren't directly related to any particular function of the organization nor does it directly result in generating any profits. Instead, these costs simply take on the role of supporting all of the business's other functions.


title: Overhead (business)

text: Universities regularly charge administrative overhead rates on research. In the U.S. the average overhead rate is 52%, which is spent on building operation, administrative salaries and other areas not directly tied to research. Academics have argued against these charges. For example, Benjamin Ginsberg showed how overhead rates are primarily used to subsidize ballooning administrative salaries and building depreciation, neither of which directly benefit research; although it does benefit the administrators that determine university policy in his book The Fall of Faculty. An article written by Joshua Pearce in Science argued that overhead accounting practices hurt science by removing funds from research and discouraging the use of less-expensive open source hardware. He went into detail on the accounting showing how millions were wasted each year on overhead cash grabs by university administrators in ZME Science.


title: Overhead (business)

text: This includes mainly monthly and annual salaries that are agreed upon. They are considered overheads as these costs must be paid regardless of sales and profits of the company. In addition, salary differs from wage as salary is not affected by working hours and time, therefore will remain constant. In particular, this would more commonly apply to more senior staff members as they are typically signed to longer tenure contracts, meaning that their salaries are more commonly predetermined.


title: Overhead (business)

text: This includes office equipment such as printer, fax machine, computers, refrigerator, etc. They are equipment that do not directly result in sales and profits as they are only used for supporting functions that they can provide to business operations. However, equipment can vary between administrative overheads and manufacturing overheads based on the purpose of which they are using the equipment. For example, for a printing company a printer would be considered a manufacturing overhead.


title: Overhead (business)

text: This includes the cost of hiring external law and audit firms on behalf of the company. This would not apply if company has own internal lawyers and audit plans. Due to regulations and necessary annual audits to ensure a satisfactory work place environment, these costs often cannot be avoided. Also, since these costs do not necessarily contribute directly to sales, they are considered as indirect overheads. Although in most cases necessary, these costs can sometimes be avoided and reduced.


title: Overhead (business)

text: Many companies provide usage of company cars as a perk for their employees. Since these cars do not contribute directly to sales and profits, they are considered an overhead. Similar company perks that are a one-off or constant payment such as partner contract fees with a gym will also fall under administrative overheads.


title: Overhead (business)

text: This will include company-paid business travels and arrangements. As well as refreshments, meals, and entertainment fees during company gatherings. Although one might argue that these costs motivate workers to become more productive and efficient, the majority of economists agree that these costs do not directly contribute to sales and profits, therefore shall be categorized as an administrative overhead. Despite these costs occurring periodically and sometimes without prior preparation, they are usually one-off payments and are expected to be within the company's budget for travel and entertainment.


title: Overhead (business)

text: Manufacturing overheads are all costs endured by a business that is within the physical platform in which the product or service is created. Difference between manufacturing overheads and administrative overheads is that manufacturing overheads are categorized within a factory or office in which the sale takes place. Whilst administrative overheads is typically categorized within some sort of back-office or supporting office. Although there are cases when the two physical buildings may overlap, it is the usage of the overheads that separates them.


title: Overhead (business)

text: Although the general concept is identical to the example under administrative overheads, the key difference is the role of the employee. In the case of manufacturing overheads, employees would have roles such as maintenance personnel, manufacturing managers, materials management staff, and quality control staff. It would also include the set wages for janitorial staff members. Once again, the key difference lies in the nature of their respective jobs and the physical location in which their jobs are carried out.


title: Overhead (business)

text: This refers to the reduction in value of equipments as it becomes older and more obsolete. For example, if a printer has a potential useful life span of 5 years, the amount that it can be sold for will decrease each year. Therefore, this value in depreciation is calculated as a manufacturing overhead. Moreover, this also applies to vehicles as they tend to depreciate significantly after the first year. When calculating manufacturing overheads, accountants mainly use two methods: straight-line method and declining balance method.


title: Overhead (business)

text: Every single property unless government owned is subject to some form of property tax. Therefore, the taxes on production factories are categorized as manufacturing overheads as they are costs which cannot be avoided nor cancelled. In addition, property taxes do not change in relation to the business's profits or sales and will likely remain the same unless a change by the government administration.


title: Overhead (business)

text: Unless the business decides to purchase land and build its own factory, it will be subject to some sort of rent due to the amount of capital required to build a privately owned factory. Therefore, this rent must be paid to the landlord on a regular basis regardless of the performance of the business. Although the rent for the building provides the physical platform for the company to produce its products and services, it is not a direct contributor.


title: Overhead (business)

text: This would vary depending on how the utility bill is structured. In the case of it being an overhead, the utility bill is pre-negotiated meaning that the monthly utility bill will be the same regardless of the amount in which the factory actually consumes. This will only be relevant in various countries where there is an option for standardized utility bills. However, due to the vast consumption of electricity, gas, and water in most factories, most companies tend to not have standardized utility bills as it tends to be more expensive. Standardized utility bills are also oftentimes discouraged by governments as it leads to wastage of resources and negative externalities of production.


title: Overhead (business)

text: For most businesses, business overheads are calculated by accountants for budgeting purposes but also often so the business has an idea of how much they must charge consumers in order to make a profit. The following are common accounting tools which take account of business overheads.


title: Overhead (business)

text: The break-even analysis determines the point which the business's revenue is equivalent to the costs required to receive that revenue. It first calculates a margin of safety (the point which the revenue exceeds the break-even point) as that is the "safe" amount which the revenue can fall whilst still remaining to be above the break-even point. The graph on the right shows a typical break-even chart. Contribution refers to sales of the product or service, it can also be interpreted as the business's revenue stream. Fixed costs in this case serves the same purpose as business overheads, it will simply be shown as a straight horizontal line on the graph as shown.


title: Overhead (business)

text: In economics, revenue curves are often illustrated to show whether or not a business should stay in business, or shut down. In theory, if a business is able cover variable operational costs but unable to cover business overheads in the short run, the business should remain in business. On the other hand, if the business is not even able to cover operational costs, it should shut down. Although this rule largely differs depending on the size of the business, the business's cash-flow, and the competitive nature of the business, it serves as a model rule for most small competitive businesses to operate on.


title: Overhead (business)

text: Activity-based costing (ABC) aims to reduce the proportion of costs treated as overheads by allocating costs to each activity involved in the production of a product or delivery of a service.


title: Overhead (business)

text: Balance sheet is a financial statement which outlines a company's financial assets, liabilities, and shareholder's equity at a specific time. Both assets and liabilities are separated into two categories depending on their time frame; current and long-term. Business overheads in particular fall under current liabilities as they are costs for which the company must pay on a relatively short-term/immediate basis. Although the balance sheet by itself does not offer much information, it is a useful piece of financial information when combined with other documents such as the income statement or ratio analysis as it offers a diverse and well-rounded description of the company's financial position.


title: Western African Ebola virus epidemic

text: The 2013–2016 epidemic of Ebola virus disease, centered in Western Africa, was the most widespread outbreak of the disease in history. It caused major loss of life and socioeconomic disruption in the region, mainly in Guinea, Liberia and Sierra Leone. The first cases were recorded in Guinea in December 2013; later, the disease spread to neighbouring Liberia and Sierra Leone, with minor outbreaks occurring in Nigeria and Mali. Secondary infections of medical workers occurred in the United States and Spain. In addition, isolated cases were recorded in Senegal, the United Kingdom and Italy. The number of cases peaked in October 2014 and then began to decline gradually, following the commitment of substantial international resources. <section begin="casesasof" />


title: Western African Ebola virus epidemic

text:
It caused significant mortality, with a considerable case fatality rate. By the end of the epidemic, 28,616 people had been infected; of these, 11,310 had died, for a case-fatality rate of 40%.
, the World Health Organization (WHO) and respective governments reported a total of
28,646
 suspected cases and
11,323
 deaths

 (39.5%), though the WHO believes that this substantially understates the magnitude of the outbreak.


title: Western African Ebola virus epidemic

text: On 8 August 2014, a Public Health Emergency of International Concern was declared and on 29 March 2016, the WHO terminated the Public Health Emergency of International Concern status of the outbreak. Subsequent flare-ups occurred; the epidemic was finally declared over on 9 June 2016, 42 days after the last case tested negative on 28 April 2016 in Monrovia.


title: Western African Ebola virus epidemic

text: The outbreak left about 17,000 survivors of the disease, many of whom report post-recovery symptoms termed post-Ebola syndrome, often severe enough to require medical care for months or even years. An additional cause for concern is the apparent ability of the virus to "hide" in a recovered survivor's body for an extended period of time and then become active months or years later, either in the same individual or in a sexual partner. In December 2016, the WHO announced that a two-year trial of the rVSV-ZEBOV vaccine appeared to offer protection from the variant of EBOV responsible for the Western Africa outbreak. The vaccine is considered to be effective and is the only prophylactic which offers protection; hence, 300,000 doses have been stockpiled. rVSV-ZEBOV received regulatory approval in 2019.


title: Western African Ebola virus epidemic

text: Ebola virus disease (commonly known as "Ebola") was first described in 1976 in two simultaneous outbreaks in the Democratic Republic of the Congo and what is now South Sudan. The 2013–2016 outbreak, caused by Ebola virus (EBOV), was the first anywhere in the world to reach epidemic proportions. Previous outbreaks had been brought under control in a much shorter period of time. Extreme poverty, dysfunctional healthcare systems, distrust of government after years of armed conflict, and the delay in responding for several months, all contributed to the failure to control the epidemic. Other factors, per media reports, included local burial customs of washing the body and the unprecedented spread of Ebola to densely populated cities.


title: Western African Ebola virus epidemic

text: As the outbreak progressed, the media reports, many hospitals, short on both staff and supplies, were overwhelmed and closed down, leading some health experts to state that the inability to treat other medical needs may have been causing "an additional death toll [that is] likely to exceed that of the outbreak itself". Hospital workers, who worked closely with the highly contagious body fluids of the victims, were especially vulnerable to contracting the virus; in August 2014, the WHO reported that ten per cent of the dead had been healthcare workers. In September 2014, it was estimated that the affected countries' capacity for treating Ebola patients was insufficient by the equivalent of 2,122 beds; however, by December 2014 there were enough beds to treat and isolate all reported cases, although the uneven distribution of cases was resulting in serious shortfalls in some areas.


title: Western African Ebola virus epidemic

text: The WHO has been widely criticised for its delay in taking action to address the epidemic. On 8 August 2014, it declared the outbreak a public health emergency of international concern. By September 2014, Médecins Sans Frontières/Doctors Without Borders (MSF), the non-governmental organisation with the largest working presence in the affected countries, had grown increasingly critical of the international response. Speaking on 3 September, the International President of MSF spoke out concerning the lack of assistance from United Nations (UN) member countries: "Six months into the worst Ebola epidemic in history, the world is losing the battle to contain it." In a 26 September statement, the WHO stated that "[t]he Ebola epidemic ravaging parts of Western Africa is the most severe acute public health emergency seen in modern times" and its Director-General called the outbreak "the largest, most complex and most severe we've ever seen". In March 2015, the United Nations Development Group reported that due to a decrease in trade, closing of borders, flight cancellations, and drop in foreign investment and tourism activity fuelled by stigma, the epidemic had resulted in vast economic consequences in both the affected areas in Western Africa and even in other African nations with no cases of Ebola.


title: Western African Ebola virus epidemic

text: On 28 January 2015, the WHO reported that for the first time since the week ending 29 June 2014, there had been fewer than 100 new confirmed cases reported in a week in the three most-affected countries. The response to the epidemic then moved to a second phase, as the focus shifted from slowing transmission to ending the epidemic. On 8 April 2015, the WHO reported a total of only 30 confirmed cases, and the weekly update for 29 July reported only seven new cases. Cases continued to gradually dwindle and on 7 October 2015, all three of the most seriously affected countries, per media reports, recorded their first joint week without any new cases. However, as of late 2015, while the large-scale epidemic had ended, according to media reports, sporadic new cases were still being recorded, frustrating hopes that the epidemic could be declared over.


title: Western African Ebola virus epidemic

text: On 31 July 2015, the WHO announced "an extremely promising development" in the search for an effective vaccine for Ebola virus disease. While the vaccine had shown high efficacy in individuals, more conclusive evidence was needed regarding its capacity to protect populations through herd immunity. In August 2015, after substantial progress in reducing the scale of the epidemic, the WHO held a meeting to work out a "Comprehensive care plan for Ebola survivors" and identify research needed to optimise clinical care and social well-being. Stating that "the Ebola outbreak has decimated families, health systems, economies, and social structures", the WHO called the aftermath of the epidemic "an emergency within an emergency." Of special concern is recent research that shows some Ebola survivors experience a so-called "post-Ebola Syndrome", with symptoms so severe that survivors may require medical care for months and even years. As the main epidemic was coming to an end in December 2015, the UN announced that 22,000 children had lost one or both parents to Ebola. On 29 March 2016, the Director-General of WHO terminated the Public Health Emergency of International Concern status of the Western African Ebola virus epidemic.


title: Western African Ebola virus epidemic

text: It is generally believed that a one or two-year-old boy, later identified as Emile Ouamouno, who died in December 2013 in the village of Méliandou, Guéckédou Prefecture, Guinea, was the index case of the Western African epidemic. Scientists have deduced that bats are involved in the spread of the virus, and, incidentally, the boy's home was in the vicinity of a large colony of Angolan free-tailed bats, according to media reports. His mother, sister, and grandmother, per media reports later became ill with similar symptoms and also died; people infected by these initial cases spread the disease to other villages. There was knowledge of "Tai Forest virus" in Côte d'Ivoire, which had resulted in one human transmission in 1994. Thus, these early cases were diagnosed as other conditions more common to the area and the disease had several months to spread before it became recognised as Ebola.


title: Western African Ebola virus epidemic

text: On 25 March 2014, the WHO indicated that Guinea's Ministry of Health had reported an outbreak of Ebola virus disease in four southeastern districts, and that suspected cases in the neighbouring countries of Liberia and Sierra Leone were being investigated. In Guinea, a total of 86 suspected cases, including 59 deaths, had been reported as of 24 March. By late May, the outbreak had spread to Conakry, Guinea's capital—a city of about two million people. On 28 May, the total number of reported cases had reached 281, with 186 deaths.


title: Western African Ebola virus epidemic

text: In Liberia, the disease was reported in four counties by mid-April 2014 and cases in Liberia's capital Monrovia were reported in mid-June. The outbreak then spread to Sierra Leone and progressed rapidly. By 17 July, the total number of suspected cases in the country stood at 442, surpassing those in Guinea and Liberia. By 20 July, additional cases of the disease had been reported by the media in the Bo District, while the first case in Freetown, Sierra Leone's capital, was reported in late July.


title: Western African Ebola virus epidemic

text: As the epidemic progressed, a small outbreak occurred in Nigeria that resulted in 20 cases and another in Mali with 7 cases. Four other countries (Senegal, Spain, the United Kingdom and the United States of America) also reported cases imported from Western Africa, with widespread and intense transmission.


title: Western African Ebola virus epidemic

text: On 31 March 2015, one year after the first report of the outbreak, the total number of cases was in excess of 25,000—with over 10,000 deaths.


title: Western African Ebola virus epidemic

text: As the epidemic waned, following international control efforts, the edition of 8 April 2015 of the WHO's "Ebola Situation Reports" stated that a total of 30 cases were reported and on 29 July 2015, the WHO weekly update reported only 7 cases—the lowest in more than a year. In October 2015, the WHO recorded its first week without any new cases, and while the large-scale epidemic appeared to have ended by late 2015, sporadic new cases continued to be reported.


title: Western African Ebola virus epidemic

text: On 14 January 2016, after all the previously infected countries had been declared Ebola-free, the WHO reported that "all known chains of transmission have been stopped in Western Africa", but cautioned that further small outbreaks of the disease could occur in the future. The following day, Sierra Leone confirmed its first new case since September 2015.


title: Western African Ebola virus epidemic

text: On 25 March 2014, the WHO reported an outbreak of Ebola virus disease in four southeastern districts of Guinea with a total of 86 suspected cases, including 59 deaths, and MSF assisted the Ministry of Health by establishing Ebola treatment centres in the epicentre of the outbreak. On 31 March, the U.S. Centers for Disease Control and Prevention (CDC) sent a five-person team to assist in the response to the outbreak. Thinking that spread of the virus had been contained, MSF closed its treatment centres in May, leaving only a skeleton staff to handle the Macenta region. However, in late August, according to media reports, large numbers of new cases reappeared in the region.


title: Western African Ebola virus epidemic

text: In February 2015, media reported that Guinea recorded a rise in cases for the second week in a row, health authorities stated that this was related to the fact that they "were only now gaining access to faraway villages", where violence had previously prevented them from entering. On 14 February, violence erupted and an Ebola treatment centre near the centre of the country was destroyed. Guinean Red Cross teams said they had suffered an average of 10 attacks a month over the previous year; MSF reported that acceptance of Ebola education remained low and that further violence against their workers might force them to leave.


title: Western African Ebola virus epidemic

text: Resistance to interventions by health officials among the Guinean population remained greater than in Sierra Leone and Liberia, per media reports, raising concerns over its impact on ongoing efforts to halt the epidemic; in mid-March, there were 95 new cases and on 28 March, and a 45-day "health emergency" was declared in 5 regions of the country. On 22 May, the WHO reported another rise in cases, per media reports, which was believed to have been due to funeral transmissions; on 25 May, six persons were placed in prison isolation after they were found travelling with the corpse of an individual who had died of the disease, on 1 June, it was reported that violent protests in a north Guinean town at the border with Guinea-Bissau had caused the Red Cross to withdraw its workers.


title: Western African Ebola virus epidemic

text: In late June 2015, the WHO reported that "weekly case incidence has stalled at between 20 and 27 cases since the end of May, whilst cases continue to arise from unknown sources of infection, and to be detected only after post-mortem testing of community deaths". On 29 July, a sharp decline in cases was reported, with only a single case, per media reports left by the end of the week, the number of cases eventually plateaued at 1 or 2 cases per week after the beginning of August. On 28 October, an additional 3 cases were reported in the Forécariah Prefecture by the WHO. On 6 November, a media report indicated Tana village to be the last known place with Ebola in the country, and on 11 November, WHO indicated that no Ebola cases were reported in Guinea; this was the first time since the epidemic began, that no cases had been reported in any country. On 15 November, the last quarantined individuals were released, per media reports and on 17 November, the last Ebola patient in Guinea—a 3-week-old baby—had recovered; the 42-day countdown toward the country being declared Ebola-free started on 17 November, the day after the patient yielded a second consecutive negative blood test. The patient was discharged from the hospital on 28 November, per media reports on 29 December 2015, upon expiration of the 42-day waiting period, the WHO declared Guinea Ebola-free.


title: Western African Ebola virus epidemic

text: On 17 March 2016, the government of Guinea reported, per the media, that 2 people had again tested positive for Ebola virus in Korokpara, it was also reported that they were from the village where members of one family had recently died from vomiting (and diarrhea). On 19 March, it was also reported by the media that another individual had died due to the virus at the treatment centre in Nzerekore, consequently, the country's government quarantined an area around the home where the cases took place. On 22 March, the media reported that medical authorities in Guinea had quarantined 816 suspected contacts of the prior cases (more than 100 individuals were considered high-risk); the same day, Liberia ordered its border with Guinea closed. Macenta Prefecture, from Korokpara, registered Guinea's fifth fatality due to Ebola virus disease within the same period. On 29 March, it was reported that about 1,000 contacts had been identified (142 of them high-risk), and on 30 March 3 more confirmed cases were reported from the sub-prefecture of Koropara. On 1 April, it was reported by the media, that possible contacts, which numbered in the hundreds, had been vaccinated with an experimental vaccine using a ring vaccination approach.

text: On 5 April 2016, it was reported via the media, that there had been 9 new cases of Ebola since the virus resurfaced, out of which 8 were fatal; on 1 June, after the stipulated waiting period, the WHO again declared Guinea Ebola-free, after which the country entered a 90-day period of heightened surveillance that was concluded on 30 August 2016.


title: Western African Ebola virus epidemic

text: In September 2016, findings were published suggesting that the resurgence in Guinea was caused by an Ebola survivor who, after eight months of abstinence, had sexual relations with several partners, including the first victim in the new outbreak. The disease was also spread to Liberia by a woman who went there after her husband had died of Ebola.


title: Western African Ebola virus epidemic

text: The first person reported infected in Sierra Leone, according to media reports, was a tribal healer who had been treating Ebola patients from across the nearby border with Guinea and who died on 26 May 2014; according to tribal tradition, her body was washed for burial, and this appears to have led to infections in women from neighbouring towns. On 11 June Sierra Leone shut its borders for trade with Guinea and Liberia and closed some schools in an attempt to slow the spread of the virus; on 30 July the government began to deploy troops to enforce quarantines, and by 15 October the last district in Sierra Leone previously untouched by the disease had declared Ebola cases.


title: Western African Ebola virus epidemic

text: During the first week of November reports told of a worsening situation due to intense transmission in Freetown. According to the Disaster Emergency Committee, food shortages resulting from aggressive quarantines were making the situation worse, and on 4 November media reported that thousands had violated quarantine in search of food in the town of Kenema. With the number of cases continuing to increase, an MSF coordinator described the situation in Sierra Leone as "catastrophic", saying, "there are several villages and communities that have been basically wiped out ... Whole communities have disappeared but many of them are not in the statistics." In mid-November the WHO reported that, while there was some evidence that the number of cases were no longer rising in Guinea and Liberia, steep increases persisted in Sierra Leone.


title: Western African Ebola virus epidemic

text: On 9 December 2014 news reports described the discovery of "a grim scene"—piles of bodies, overwhelmed medical personnel and exhausted burial teams—in the remote eastern Kono District. On 15 December the CDC indicated that their main concern was Sierra Leone, where the epidemic had shown no signs of abating as cases continued to rise exponentially; by the second week of December, Sierra Leone had reported nearly 400 cases—more than three times the number reported by Guinea and Liberia combined. According to the CDC, "the risk we face now [is] that Ebola will simmer along, become native and be a problem for Africa and the world, for years to come". On 17 December President Koroma of Sierra Leone launched "Operation Western Area Surge" and workers went door-to-door in the capital city looking for possible cases. The operation led to a surge in reports of cases, with 403 new ones reported between 14 and 17 December.


title: Western African Ebola virus epidemic

text: According to the 21 January 2015 WHO Situation Report, the case incidence was rapidly decreasing in Sierra Leone. However, in February and March reports indicated a rise again in the number of cases. The following month, the 5 April WHO report again disclosed a downward trend and the WHO weekly update for 29 July reported a total of only 3 new cases, the lowest in more than a year. On 17 August the country marked its first week with no new cases, and one week later the last patients were released. However, a new case emerged on 1 September, when a patient from Sella Kafta village in Kambia District tested positive for the disease after her death; her case eventually resulted in 3 other infections among her contacts.


title: Western African Ebola virus epidemic

text: On 14 September 2015 Sierra Leone's National Ebola Response Centre confirmed the death of a 16-year-old in a village in the Bombali District. It is suspected that she contracted the disease from the semen of an Ebola survivor who had been discharged in March 2015. On 27 September a new 42-day countdown began to declare the country Ebola-free, which eventually occurred on 7 November 2015; thereafter, the country increased its vigilance on the Guinean border.


title: Western African Ebola virus epidemic

text: Sierra Leone had entered a 90-day period of enhanced surveillance that was scheduled to end on 5 February 2016, when, on 14 January, a new Ebola death was reported in the Tonkolili District. Prior to this case, the WHO had advised that "we still anticipate more flare-ups and must be prepared for them. A massive effort is underway to ensure robust prevention, surveillance and response capacity across all three countries by the end of March." On 16 January aid workers reported that a woman had died of the virus and that she may have exposed several individuals; the government later announced that 100 people had been quarantined. Investigations indicated that the deceased was a female student from Lunsar, in Port Loko District, who had gone to Kambia District on 28 December 2015 before returning symptomatic. She had also visited Bombali District to consult a herbalist, and had later gone to a government hospital in Magburaka. The WHO indicated that there were 109 contacts (28 of them high-risk), that there were another 3 missing contacts, and that the source or route of transmission that caused the fatality was unknown. A second new case—confirmed by WHO spokesman Tarik Jasarevic to involve a 38-year-old relative and caregiver of the aforementioned Ebola victim—had become symptomatic on 20 Jan while under observation at a quarantine centre. On 22 January it was reported that this patient was responding to treatment. On 26 January WHO Director-General, Dr Margaret Chan officially confirmed that the outbreak was not yet over; that same day, it was also reported that Ebola restrictions had halted market activity in Kambia District amid protests. On 7 February 70 individuals were released from quarantine, and on 8 February the last Ebola patient was also released. On 17 February the WHO indicated that 2,600 Ebola survivors had accessed health assessments and eye examinations.


title: Western African Ebola virus epidemic

text: On 4 February 2016 the last known case tested negative for a second consecutive time and Sierra Leone commenced another 42-day countdown towards being declared Ebola-free. On 17 March 2016 the WHO announced that the Sierra Leone flare-up was over, and that no other chains of transmission were known to be active at that time. The media reported that Sierra Leone then entered a 90-day period of heightened surveillance, which concluded on 15 June 2016, and it was reported that by 15 July the country had discontinued testing corpses for the virus.


title: Western African Ebola virus epidemic

text: In Liberia, the disease was reported in both Lofa and Nimba counties in late March 2014. On 27 July, President Ellen Johnson Sirleaf announced that Liberia would close its borders, with the exception of a few crossing points such as Roberts International Airport, where screening centres would be established. Schools and universities were closed, and the worst-affected areas in the country were placed under quarantine.


title: Western African Ebola virus epidemic

text: With only 50 physicians in the entire country—one for every 70,000 citizens—Liberia was already in a healthcare crisis. In September, the CDC reported that some hospitals had been abandoned, while those still functioning lacked basic facilities and supplies. In October, the Liberian ambassador in Washington was reported as saying that he feared that his country may be "close to collapse"; by 24 October, all 15 counties had reported Ebola cases.


title: Western African Ebola virus epidemic

text: By November 2014, the rate of new infections in Liberia appeared to be declining and the state of emergency was lifted. The drop in cases was believed to be related to an integrated strategy combining isolation and treatment with community behaviour change, including safe burial practices, case finding and contact tracing. Roselyn Nugba-Ballah, leader of the Safe & Diginified Burial Practices Team during the crisis, was awarded the Florence Nightingale Medal in 2017 for her work during the crisis.


title: Western African Ebola virus epidemic

text: In January 2015, the MSF field coordinator reported that Liberia was down to only 5 confirmed cases. In March, after two weeks of not reporting any new cases, 3 new cases were confirmed. On 8 April, a new health minister was named in an effort to end Ebola in the country and on 26 April, MSF handed the Ebola treatment facility, ELWA-3, over to the government. On 30 April, the US shut down a special Ebola treatment unit in Liberia. The last known case of Ebola died on 27 March, and the country was officially declared Ebola-free on 9 May 2015, after 42 days without any further cases being recorded. The WHO congratulated Liberia saying, "reaching this milestone is a testament to the strong leadership and coordination of Liberian President Ellen Johnson Sirleaf and the Liberian Government, the determination and vigilance of Liberian communities, the extensive support of global partners, and the tireless and heroic work of local and international health teams." As at May 2015, the country remained on high alert against recurrence of the disease.


title: Western African Ebola virus epidemic

text: After three months with no new reports of cases, on 29 June Liberia reported that the body of a 17-year-old boy, who had been treated for malaria, tested positive for Ebola. The WHO said the boy had been in close contact with at least 200 people, who they were following up, and that "the case reportedly had no recent history of travel, contact with visitors from affected areas, or funeral attendance." A second case was confirmed on 1 July. After a third new case was confirmed on 2 July, and it was discovered that all 3 new cases had shared a meal of dog meat, researchers looked at the possibility that the meat may have been involved in the transfer of the virus. Testing of the dog's remains, however, was negative for the Ebola virus. By 9 July 3 more cases were discovered, bringing the total number of new cases to 5, all from the same area. On 14 July, a woman died of the disease in the county of Montserrado, bringing the total to 6. On 20 July, the last patients were discharged, and on 3 September 2015, Liberia was declared Ebola-free again.


title: Western African Ebola virus epidemic

text: After two months of being Ebola-free, a new case was confirmed on 20 November 2015, when a 15-year-old boy was diagnosed with the virus<ref name="Liberia New Case 20/11/2015 LA Times"></ref> and two family members subsequently tested positive as well. Health officials were concerned because the child had not recently travelled or been exposed to someone with Ebola and the WHO stated that "we believe that this is probably again, somehow, someone who has come in contact with a virus that had been persisting in an individual, who had suffered the disease months ago." Two staff of the CDC were sent to the country to help ascertain the cause of the new cases. The infected boy died on 24 November, and on 3 December 2 remaining cases were released after recovering from the disease. The 42-day countdown toward Liberia being declared Ebola-free, for the third time, started on 4 December 2015. On 16 December, the WHO reaffirmed that the cases in Liberia were the result of re-emergence of the virus in a previously infected person, and there was speculation that the boy may have been infected by an individual who became infectious once more due to pregnancy, which may have weakened her immune system. On 18 December, the WHO indicated that it still considered Ebola in Western Africa a public health emergency, though progress had been made.


title: Western African Ebola virus epidemic

text: After having completed the 42-day time period, Liberia was declared free from the virus on 14 January 2016, effectively ending the outbreak that had started in neighbouring Guinea 2 years earlier. Liberia began a 90-day period of heightened surveillance, scheduled to conclude on 13 April 2016, but on 1 April, it was reported that a new Ebola fatality had occurred, and on 3 April, a second case was reported in Monrovia. On 4 April, it was reported that 84 individuals were under observation due to contact with the 2 confirmed Ebola cases. By 7 April, Liberia had confirmed 3 new cases since the virus resurfaced and a total of 97 contacts, including 15 healthcare workers, were being monitored. The index case of the new flareup was reported to be the wife of a patient who died from Ebola in Guinea; she had travelled to Monrovia after the funeral but died from the disease. The outbreak in Guinea, in turn, had begun when a man, who had survived Ebola, had sexual intercourse with a woman and passed the virus to her, even though he had recovered more than a year earlier.


title: Western African Ebola virus epidemic

text: On 29 April, WHO reported that Liberia had discharged the last patient and had begun the 42-day countdown to be declared Ebola-free once more. According to the WHO, tests indicated that the flare-up was likely due to contact with a prior Ebola survivor's infected body fluids. On 9 June, the flare-up was declared over, and the country Ebola-free, due to the passage of the 42-day period; Liberia then entered a 90-day period of heightened surveillance, which ended on 7 September 2016. In early July 2016, a trial for males with detectable Ebola RNA in semen, started.


title: Western African Ebola virus epidemic

text: In March 2014, the Senegal Ministry of Interior closed its southern border with Guinea, but on 29 August, the health minister announced the country's first case – a university student from Guinea who was being treated in a Dakar hospital. The patient was a native of Guinea who had travelled to Dakar, arriving on 20 August. On 23 August, he sought medical care for symptoms including diarrhoea, and vomiting plus signs of fever. He received treatment for malaria but did not improve and left the facility. Still experiencing the same symptoms, on 26 August he was referred to a specialised facility for infectious diseases, and subsequently hospitalised.


title: Western African Ebola virus epidemic

text: On 28 August 2014, authorities in Guinea issued an alert informing their medical services and neighbouring countries that a person who had been in close contact with an Ebola-infected patient had escaped their surveillance system. The alert prompted testing for Ebola at the Dakar laboratory, and the positive result launched an investigation, triggering urgent contact tracing. On 10 September, it was reported that the student had recovered but health officials continued to monitor his contacts for 21 days. No further cases were reported, and on 17 October 2014, the WHO officially declared that the outbreak in Senegal had ended.


title: Western African Ebola virus epidemic

text: The WHO officially commended the Senegalese government, and in particular the President Macky Sall and the Minister of Health, Dr Awa Coll-Seck, for their response in quickly isolating the patient and tracing and following up 74 contacts, as well as for their public awareness campaign. This acknowledgement was also extended to MSF and the CDC for their assistance.


title: Western African Ebola virus epidemic

text: The first case in Nigeria was a Liberian-American, who flew from Liberia to Nigeria's most populated city of Lagos on 20 July 2014. On 6 August 2014, the Nigerian health minister told reporters that one of the nurses that attended to the Liberian had died from the disease. 5 newly confirmed cases were being treated at an isolation ward.


title: Western African Ebola virus epidemic

text: On 22 September 2014, the Nigerian health ministry announced, "As of today, there is no case of Ebola in Nigeria." According to the WHO, 20 cases and 8 deaths were confirmed, including the imported case, who also died. 4 of the dead were health workers who had cared for the index case.


title: Western African Ebola virus epidemic

text: The WHO's representative in Nigeria officially declared the country Ebola-free on 20 October 2014, after no new active cases were reported in the follow up contacts, stating it was a "spectacular success story". Nigeria was the first African country to be declared Ebola free. This was largely due to the early quarantine efforts of Dr. Ameyo Stella Adadevoh at First Consultants Medical Centre in Lagos.


title: Western African Ebola virus epidemic

text: On 23 October 2014, the first case of Ebola virus disease in Mali was confirmed in the city of Kayes—a two-year-old girl who had arrived with a family group from Guinea, and died the next day. Her father had worked for the Red Cross in Guinea and also in a private health clinic; he had died earlier in the month, likely from an Ebola infection contracted in the private clinic. It was later established that a number of family members had also died of Ebola. The family had returned to Mali after the father's funeral via public bus and taxi—a journey of more than . All contacts were followed for 21 days, with no further spread of the disease reported.


title: Western African Ebola virus epidemic

text: On 12 November 2014, Mali reported deaths from Ebola in an outbreak unconnected with the first case in Kayes. The first probable case was an imam who had fallen ill on 17 October in Guinea and was transferred to the Pasteur Clinic in Mali's capital city, Bamako, for treatment. He was treated for kidney failure but was not tested for Ebola; he died on 27 October and his body returned to Guinea for burial. A nurse and a doctor who had treated the imam subsequently fell ill with Ebola and died. The next 3 cases were related to the imam as well: a man who had visited the imam while he was in hospital, his wife and his son. On 22 November, the final case related to the imam was reported—a friend of the Pasteur Clinic nurse who had died from the Ebola virus. On 12 December, the last case in treatment recovered and was discharged, "so there are no more people sick with Ebola in Mali", according to a Ministry of Health source. On 16 December, Mali released the final 13 individuals who were being quarantined and 24 days later (18 January 2015) without new cases, the country was declared Ebola-free.


title: Western African Ebola virus epidemic

text: On 29 December 2014, Pauline Cafferkey, a British aid worker who had just returned to Glasgow from Sierra Leone, was diagnosed with Ebola. She was treated and declared to be free of infection and released from hospital on 24 January 2015. On 8 October, she was readmitted for complications caused by the virus and was in "serious" condition, according to a hospital report. On 14 October, her condition was listed as "critical" and 58 individuals were being monitored and 25 received an experimental vaccination, being close contacts. On 21 October, it was reported that she had been diagnosed with meningitis caused by the virus persisting in her brain. On 12 November, she was released from hospital after making a full recovery. However, on 23 February, Ms. Cafferkey was admitted for a third time, "under routine monitoring by the Infectious Diseases Unit ... for further investigations", according to a spokesperson.


title: Western African Ebola virus epidemic

text: On 12 May 2015, it was reported that a nurse, who had been working in Sierra Leone, had been diagnosed with Ebola after returning home to the Italian island of Sardinia. He was treated at Spallanzani Hospital, the national reference centre for Ebola patients. On 10 June, it was reported that he had recovered and was disease-free and he was released from hospital.


title: Western African Ebola virus epidemic

text: On 5 August 2014, the Brothers Hospitallers of Saint John of God confirmed that Brother Miguel Pajares, who had been volunteering in Liberia, had become infected. He was evacuated to Spain and died on 12 August. On 21 September it was announced that Brother Manuel García Viejo, another Spanish citizen who was medical director at the St John of God Hospital Sierra Leone in Lunsar, had been evacuated to Spain from Sierra Leone after being infected with the virus. His death was announced on 25 September.


title: Western African Ebola virus epidemic

text: In October 2014, a nursing assistant, Teresa Romero, who had cared for these patients became unwell and on 6 October tested positive for Ebola, making this the first confirmed case of Ebola transmission outside of Africa. On 19 October, it was reported that Romero had recovered, and on 2 December the WHO declared Spain Ebola-free following the passage of 42 days since Teresa Romero was found to be cured.


title: Western African Ebola virus epidemic

text: On 30 September 2014, the CDC declared its first case of Ebola virus disease. It disclosed that Thomas Eric Duncan became infected in Liberia and travelled to Dallas, Texas on 20 September. On 26 September, he fell ill and sought medical treatment, but was sent home with antibiotics. He returned to the hospital by ambulance on 28 September and was placed in isolation and tested for Ebola. He died on 8 October. Two cases stemmed from Duncan, when two nurses that had treated him tested positive for the virus on 10 and 14 October and ended when they were declared Ebola-free on 24 and 22 October, respectively.


title: Western African Ebola virus epidemic

text: A fourth case was identified on 23 October 2014, when Craig Spencer, an American physician who had returned to the United States after treating Ebola patients in Western Africa, tested positive for the virus. This case, however, had no relation to those originating from Duncan. Spencer recovered and was released from hospital on 11 November.


title: Western African Ebola virus epidemic

text: A number of people who had become infected with Ebola were medically evacuated for treatment in isolation wards in Europe or the US. They were mostly health workers with one of the NGOs in Western Africa. With the exception of a single isolated case in Spain, no secondary infections occurred as a result of the medical evacuations. The US accepted four evacuees and three were flown to Germany.


title: Western African Ebola virus epidemic

text: France, Italy, the Netherlands, Norway, Switzerland, and the United Kingdom received two patients (and five who were exposed).


title: Western African Ebola virus epidemic

text: In August 2014, the WHO reported an outbreak of Ebola virus in the Boende District, part of the northern Équateur province of the Democratic Republic of the Congo (DRC), where 13 people were reported to have died of Ebola-like symptoms. Genetic sequencing revealed that this outbreak was caused by the Zaire Ebola species, which is native to the DRC; there have been seven previous Ebola outbreaks in the country since 1976. The virology results and epidemiological findings indicated no connection to the epidemic in Western Africa.


title: Western African Ebola virus epidemic

text: The index case was initially reported to have been a woman from Ikanamongo Village, who became ill with symptoms of Ebola after she had butchered a bush animal. However, later findings suggested that there may have been several previous cases, and it was reported that pigs in the village may have been infected with Ebola some time before the first human case occurred. The WHO declared the outbreak over on 21 November 2014, after a total of 66 cases and 49 deaths.


title: Western African Ebola virus epidemic

text: Ebola virus disease is caused by four of six viruses classified in the genus "Ebolavirus". Of the four disease-causing viruses, Ebola virus (formerly and often still called the Zaire Ebola virus) is dangerous and is the virus responsible for the epidemic in Western Africa.


title: Western African Ebola virus epidemic

text: Since the discovery of the viruses in 1976, when outbreaks occurred in South Sudan (then Sudan) and Democratic Republic of the Congo (then Zaire), Ebola virus disease had been confined to areas in Middle Africa, where it is native. With the current outbreak, it was initially thought that a new species native to Guinea might be the cause, rather than being imported from Middle to Western Africa. However, further studies have shown that the outbreak was likely caused by an Ebola virus lineage that spread from Middle Africa via an animal host within the last decade, with the first viral transfer to humans in Guinea.


title: Western African Ebola virus epidemic

text: In a study done by Tulane University, the Broad Institute and Harvard University, in partnership with the Sierra Leone Ministry of Health and Sanitation, researchers provided information about the origin and transmission of the Ebola virus that set the Western African outbreak apart from previous ones, including 341 genetic changes in the virion. Five members of the research team became ill and died from Ebola before the study was published in August 2014.


title: Western African Ebola virus epidemic

text: In a report released in August 2014, researchers tracked the spread of Ebola in Sierra Leone from the group first infected—13 women who had attended the funeral of the traditional healer, where they contracted the disease—giving them a unique opportunity to track how the virus had changed. This provided "the first time that the real evolution of the Ebola virus [could] be observed in humans." The research showed that the outbreak in Sierra Leone was sparked by at least two distinct lineages introduced from Guinea at about the same time. It is not clear whether the traditional healer was infected with both variants, or if perhaps one of the women attending the funeral was independently infected. As the Sierra Leone epidemic progressed, one virus lineage disappeared from patient samples, while a third one appeared.


title: Western African Ebola virus epidemic

text: In January 2015, the media stated researchers in Guinea had reported mutations in the virus samples that they were looking at. According to them, "we've now seen several cases that don't have any symptoms at all, asymptomatic cases. These people may be the people who can spread the virus better, but we still don't know that yet. A virus can change itself to [become] less deadly, but more contagious and that's something we are afraid of." A 2015 study suggested that accelerating the rate of mutation of the Ebola virus could make the virus less capable of infecting humans. In this animal study, the virus became practically non-viable, consequently increasing survival.


title: Western African Ebola virus epidemic

text: The initial infection is believed to occur after an Ebola virus is transmitted to a human by contact with an infected animal's body fluids. Evidence strongly implicates bats as the reservoir hosts for ebolaviruses (however, despite considerable research, infectious ebolaviruses have never been recovered from bats).


title: Western African Ebola virus epidemic

text: Bats drop partially eaten fruit and pulp, then land mammals such as gorillas and duikers feed on this fallen fruit. This chain of events forms a possible indirect means of transmission from the natural host to animal populations. As primates in the area were not found to be infected and fruit bats do not live near the location of the initial zoonotic transmission event in Meliandou, Guinea, it is suspected that the index case occurred after a child had contact with an insectivorous bat from a colony of Angolan free-tailed bats near the village.


title: Western African Ebola virus epidemic

text: On 12 January, the journal "Nature" reported that the virus emergence could be found by studying how bush-meat hunters interacted with the ecosystem. The continent of Africa has experienced deforestation in several areas or regions; this may contribute to recent outbreaks, including this epidemic, as initial cases have been in the proximity of deforested lands where fruit-eating bats natural habitat may be affected, though 100% evidence does not as yet exist.


title: Western African Ebola virus epidemic

text: Prior to this outbreak, it was believed that human-to-human transmission occurred only via direct contact with blood or bodily fluids from an infected person who is showing symptoms of infection, by contact with the body of a person who had died of Ebola, or by contact with objects recently contaminated with the body fluids of an actively ill infected person.


title: Western African Ebola virus epidemic

text: It is now known that the Ebola virus can be transmitted sexually. Over time, studies have suggested that the virus can persist in seminal fluid, with a study released in September 2016 suggesting that the virus may survive more than 530 days after infection. EBOV RNA in semen is not the same situation as perseverance of EBOV in semen, however the "clinical significance of low levels of virus RNA in convalescent" individuals who are healthy is unknown.


title: Western African Ebola virus epidemic

text: In September 2014, the WHO had reported: "No formal evidence exists of sexual transmission, but sexual transmission from convalescent patients cannot be ruled out. There is evidence that live Ebola virus can be isolated in seminal fluids of convalescent men for 82 days after onset of symptoms. Evidence is not available yet beyond 82 days." In April 2015, following a report that the RNA virus had been detected in a semen sample six months after a man's recovery, the WHO issued a statement: "For greater security and prevention of other sexually transmitted infections, Ebola survivors should consider correct and consistent use of condoms for all sexual acts beyond three months until more information is available."


title: Western African Ebola virus epidemic

text: The WHO based their new recommendations on a March 2015 case, in which a Liberian woman who had no contact with the disease other than having had unprotected sex with a man who had had the disease in October 2014, was diagnosed with Ebola. While no evidence of the virus was found in his blood, his semen revealed Ebola virus RNA closely matching the variant that infected the woman. However, "doctors don't know if there was any fully formed (and therefore infectious) virus in the guy's semen." It is known that testes are protected from the body's immune system to protect the developing sperm, and it is thought that this same protection may allow the virus to survive in the testes for an unknown time.


title: Western African Ebola virus epidemic

text: On 14 September 2015, the body of a girl who had died in Sierra Leone tested positive for Ebola and it was suspected that she may have contracted the disease from the semen of an Ebola survivor who was discharged in March 2015. According to some news reports, a new study to be published in the "New England Journal of Medicine" indicated that the RNA virus could remain in the semen of survivors for up to six months, and according to other researchers, the RNA virus could continue in semen for 82 days and maybe longer. Furthermore, Ebola RNA had been found up to 284 days post-onset of viral symptoms.


title: Western African Ebola virus epidemic

text: One of the primary reasons for the spread of the disease is the low-quality, functioning health systems in the parts of Africa where the disease occurs. The risk of transmission is increased among those caring for people infected. Recommended measures when caring for those who are infected include medical isolation via the proper use of boots, gowns, gloves, masks and goggles, and sterilizing all equipment and surfaces.


title: Western African Ebola virus epidemic

text: One of the biggest dangers of infection faced by medical staff requires their learning how to properly suit up and remove personal protective equipment.


title: Western African Ebola virus epidemic

text: Full training for wearing protective body clothing can take 10 to 14 days. Even with proper isolation equipment available, working conditions such as lack of running water, climate control, and flooring have made direct care difficult. Two American health workers who contracted the disease and later recovered said that to the best of their knowledge, their team of workers had been following "to the letter all of the protocols for safety that were developed by the [CDC] and WHO", including a full body coverall, several layers of gloves, and face protection including goggles. One of the two, a physician, had worked with patients, but the other was assisting workers to get in and out of their protective gear while wearing protective gear herself.


title: Western African Ebola virus epidemic

text: Difficulties in attempting to halt transmission have also included the multiple disease outbreaks across country borders. Dr Peter Piot, the scientist who co-discovered the Ebola virus, stated that the outbreak was not following its usual linear patterns as mapped out in earlier outbreaks—this time the virus was "hopping" all over the Western African epidemic region. Furthermore, most past epidemics had occurred in remote regions, but this outbreak spread to large urban areas, which had increased the number of contacts an infected person might have and made transmission harder to track and break. On 9 December, a study indicated that a single individual introduced the virus into Liberia, causing the most cases of the disease in that country.


title: Western African Ebola virus epidemic

text: In August 2014, the WHO published a road map of the steps required to bring the epidemic under control and to prevent further transmission of the disease within Western Africa; the coordinated international response worked towards realising this plan.


title: Western African Ebola virus epidemic

text: Contact tracing is an essential method of preventing the spread of the disease, this requires effective community surveillance so that a possible case of Ebola can be registered and accurately diagnosed as soon as possible, and subsequently finding everyone who has had close contact with the case and tracking them for 21 days. However, this requires careful record-keeping by properly trained and equipped staff. WHO Assistant Director-General for Global Health Security, Keiji Fukuda, said on 3 September 2014, "We don't have enough health workers, doctors, nurses, drivers, and contact tracers to handle the increasing number of cases." There was a massive effort to train volunteers and health workers, sponsored by United States Agency for International Development (USAID). According to WHO reports, 25,926 contacts from Guinea, 35,183 from Liberia and 104,454 from Sierra Leone were listed and traced as of 23 November 2014. According to one study, it is important to have a public awareness campaign to inform the affected community about the importance of contact tracing, so that true information can be obtained from the community.

text: To reduce the spread, the WHO recommended raising community awareness of the risk factors for Ebola infection and the protective measures individuals can take. These include avoiding contact with infected people and regular hand washing using soap and water. A condition of extreme poverty exists in many of the areas that experienced a high incidence of infections. According to the director of the NGO Plan International in Guinea, "The poor living conditions and lack of water and sanitation in most districts of Conakry pose a serious risk that the epidemic escalates into a crisis. People do not think to wash their hands when they do not have enough water to drink." One study showed that once people had heard of the Ebola virus disease, hand washing with soap and water improved, though socio-demographic factors influenced hygiene.

text: A number of organisations enrolled local people to conduct public awareness campaigns among the communities in Western Africa. "... what we mean by social mobilization is to try to convey the right messages, in terms of prevention measures, adapted to the local context—adapted to the cultural practices in a specific area," said Vincent Martin, FAO's representative in Senegal.

text: Denial in some affected countries also made containment efforts difficult. Language barriers and the appearance of medical teams in protective suits sometimes increased fears of the virus. In Liberia, a mob attacked an Ebola isolation centre, stealing equipment and "freeing" patients while shouting "There's no Ebola." Red Cross staff were forced to suspend operations in southeast Guinea after they were threatened by a group of men armed with knives. In September, in the town of Womey in Guinea, suspicious inhabitants wielding machetes murdered at least eight aid workers and dumped their bodies in a latrine.

text: An August 2014 study found that nearly two-thirds of Ebola cases in Guinea were believed to be due to burial practices including washing of the body of one who had died.


title: Western African Ebola virus epidemic

text: In November, WHO released a protocol for the safe and dignified burial of people who die from Ebola virus disease. It encouraged the inclusion of family and clergy, and gave specific instructions for Muslim and Christian burials. In the 21 January 2015 WHO road map update, it was reported that 100% of districts in Sierra Leone and 71% of districts in Guinea had a list of key religious leaders who promoted safe and dignified burials. Speaking on 27 January 2015, Guinea's Grand Imam, the country's highest cleric, gave a very strong message saying, "There is nothing in the Koran that says you must wash, kiss or hold your dead loved ones," and he called on citizens to do more to stop the virus by practising safer burying rituals that do not compromise tradition.

text: During the height of the epidemic, most schools in the three most affected countries were shut down and remained closed for several months. During the period of closure UNICEF and its partners established strict hygiene protocols to be used when the schools were reopened in January 2015. They met with thousands of teachers and administrators to work out hygiene guidelines. Their efforts included installing hand-washing stations and distributing millions of bars of soap and chlorine and plans for taking the temperature of children and staff at the school gate. Their efforts were complicated by the fact that less than 50% of the schools in these three countries had access to running water. In August 2015, UNICEF released a report that stated, "Across the three countries, there have been no reported cases of a student or teacher being infected at a school since strict hygiene protocols were introduced when classes resumed at the beginning of the year after a months-long delay caused by the virus." Researchers presented evidence indicating that infected people that lived in low socioeconomic areas were more likely to transmit the virus to other socioeconomic status (SES) communities, in contrast to individuals in higher SES areas who were infected as well. Another study showed that, in Guinea, a satisfactory knowledge had not altered the level of comprehensive knowledge about the virus. As a consequence, the high level of misinterpretation was responsible for a low comprehensive knowledge about the virus; 82% of individuals believed that Ebola was the result of a virus (36.2% thought that a higher power had caused it). A study on Nigeria's success story stated that, in this case, a prompt response by the government and proactive public health measures had resulted in the quick control of the outbreak.

text: During the height of the crisis, Wikipedia's Ebola page received 2.5 million page views per day, making Wikipedia one of the world's most highly used sources of trusted medical information regarding the disease.

text: There was serious concern that the disease would spread further within Western Africa or elsewhere in the world, such as:


title: Western African Ebola virus epidemic

text: No proven Ebola virus-specific treatment presently exists; however, measures can be taken to improve a patient's chances of survival. Ebola symptoms may begin as early as two days or as long as 21 days after one is exposed to the virus. Symptoms usually begin with a sudden influenza-like illness characterised by feeling tired, and pain in the muscles and joints. Later symptoms may include headache, nausea, and abdominal pain; this is often followed by severe vomiting and diarrhoea. In past outbreaks, it has been noted that some patients bleed internally and/or externally; however data published in October 2014 showed that this had been a rare symptom in the Western African outbreak. Another study published in October 2014 suggested that a person's genetic makeup may play a major role in determining how an infected person's body reacts to the disease, with some infected people experiencing mild or no symptoms while others progress to a very severe stage that includes bleeding.


title: Western African Ebola virus epidemic

text: Without fluid replacement, such an extreme loss of fluids leads to dehydration, which in turn may lead to hypovolaemic shock—a condition in which there isn't enough blood for the heart to pump through the body. If a patient is alert and is not vomiting, oral rehydration therapy may be instituted, but patients who are vomiting or are delirious must be hydrated with intravenous (IV) therapy. However, administration of IV fluids is difficult in the African environment. Inserting an IV needle while wearing three pairs of gloves and goggles that may be fogged is difficult, and once in place, the IV site and line must be constantly monitored. Without sufficient staff to care for patients, needles may become dislodged or pulled out by a delirious patient. A patient's electrolytes must be closely monitored to determine correct fluid administration, for which many areas did not have access to the required laboratory services.


title: Western African Ebola virus epidemic

text: Treatment centres were overflowing with patients while others waited to be admitted; dead patients were so numerous that it was difficult to arrange for safe burials. Based on many years of experience in Africa—and several months working in the present epidemic—MSF took a conservative approach. While using IV treatment for as many patients as they could manage, they argued that improperly managed IV treatment was not helpful and may even kill a patient when not properly managed. They also said that they were concerned about further risk to already overworked staff. In 2015 experts studied the mortality rates of different treatment settings, and given the wide differences in variables that affected outcomes, adequate information had not yet been gathered to make a definitive statement about what constituted optimal care in the Western African setting. Paul Farmer of Partners in Health, an NGO that only as of January 2015 had begun to treat Ebola patients, strongly supported IV therapy for all Ebola patients stating: "What if the fatality rate isn't the virulence of disease but the mediocrity of the medical delivery?" Farmer suggested that every treatment facility should have a team that specializes in inserting IVs, or better yet, peripherally inserted central catheter lines. In 2020, viewing the information gathered from the pandemic Farmer noted that there were almost no deaths in the U.S. and European patients because they had received optimal care.


title: Western African Ebola virus epidemic

text: Ebola virus disease has a high case fatality rate (CFR), which in past outbreaks varied between 25% and 90%, with an average of about 50%. The epidemic caused significant mortality, with reported CFRs of up to 70%.


title: Western African Ebola virus epidemic

text: Care settings that have access to medical expertise may increase survival by providing good maintenance of hydration, circulatory volume, and blood pressure.


title: Western African Ebola virus epidemic

text: The disease affects males and females equally and the majority of those that contract Ebola disease are between 15 and 45 years of age. For those over 45 years, a fatal outcome was more likely in the Western African epidemic, as was also noted in preceding outbreaks.


title: Western African Ebola virus epidemic

text: Only rarely do pregnant women survive—a midwife who worked with MSF in a Sierra Leone treatment centre stated that she knew of "no reported cases of pregnant mothers and unborn babies surviving Ebola in Sierra Leone."<ref name="/Voice of America"></ref> In September 2015, the WHO issued pregnancy guidance information entitled, "Interim Guidance on Ebola Virus Disease in Pregnancy."


title: Western African Ebola virus epidemic

text: It has been suggested that the loss of human life was not limited to Ebola victims alone. Many hospitals had to shut down, leaving people with other medical needs without care. A spokesperson for the UK-based health foundation, the Wellcome Trust, said in October 2014 that "the additional death toll from malaria and other diseases [is] likely to exceed that of the outbreak itself". Dr Paul Farmer stated: "Most of Ebola's victims may well be dying from other causes: women in childbirth, children from diarrhoea, people in road accidents or from trauma of other sorts."


title: Western African Ebola virus epidemic

text: As the epidemic drew to a close in 2015, a report from Sierra Leone showed that the fear and mistrust of hospitals generated by the epidemic had resulted in an 11% decline in facility-based births, and that those receiving care before or after birth fell by about a fifth. Consequently, between May 2014 and April 2015, the deaths of women during or just after childbirth rose by almost a third and those of newborns by a quarter, compared to the previous year.


title: Western African Ebola virus epidemic

text: Research suggests that many Ebola infections are asymptomatic, meaning that some infected people show no symptoms of the disease. For example, two studies done on previous outbreaks showed that 71% of seropositive individuals did not have the clinical disease in one outbreak and another study reported that 46% of asymptomatic close contacts of patients with Ebola were seropositive. On 22 January, the WHO issued "Clinical Care for survivors of Ebola Virus Disease: interim guidance". The guidance covers specific issues like musculoskeletal pain, which is reported in up to 75% of survivors. The pain is symmetrical and more pronounced in the morning, with the larger joints most affected. There is also possible periarticular tenosynovitis affecting the shoulders. The WHO guidelines advise to distinguish non-inflammatory arthralgia from inflammatory arthritis. With regard to ocular problems, sensitivity to light and blurry vision have been indicated among survivors. Among the aftereffects of Ebola virus disease, uveitis and optic nerve disease could appear after an individual is discharged. Ocular problems could threaten sight in survivors, thus the need for prompt treatment. In treating such individuals, the WHO recommends urgent intervention if uveitis is suspected; this consists mainly of prednisone (a corticosteroid). Hearing loss has been reported in Ebola survivors 25% of the time. Treatment, in the case of acute labyrinthitis (inner ear disorder), should be given within 10 days of the onset of symptoms and prochlorperazine, a vestibular sedative, may be administered for vertigo.


title: Western African Ebola virus epidemic

text: There are at least 17,000 people who have survived infection from the Ebola virus in Western Africa; some of them have reported lingering health effects. In early November, a WHO consultant reported: "Many of the survivors are discharged with the so-called Post-Ebola Syndrome. We want to ascertain whether these medical conditions are due to the disease itself, the treatment given or chlorine used during disinfection of the patients. This is a new area for research; little is known about the post-Ebola symptoms."


title: Western African Ebola virus epidemic

text: In February 2015, a Sierra Leone physician said about half of the recovered patients she saw reported declining health and that she had seen survivors go blind. In May 2015, a senior consultant to the WHO said that the reports of eye problems were especially worrying because "there are hardly any ophthalmologists in Western Africa, and only they have the skills and equipment to diagnose conditions like uveitis that affect the inner chambers of the eye."


title: Western African Ebola virus epidemic

text: The medical director of a hospital in Liberia reported that he was seeing health problems in patients who had been in recovery for as long as nine months. Problems he was seeing included chronic pain, sometimes so severe that walking was difficult; eye problems, including uveitis; and headaches as the most common physical symptoms. "They're still very severe and impacting their life every day. These patients will need medical care for months and maybe years." A physician from the Kenema hospital in Sierra Leone reported similar health difficulties.


title: Western African Ebola virus epidemic

text: In December 2014, a British aid worker who had just returned from Sierra Leone was diagnosed with Ebola. She was treated with survivors' blood plasma and experimental drugs and declared free of disease in January 2015. However, in October 2015, she again became critically ill and was diagnosed with meningitis. In this unprecedented case it is thought that the virus remained in her brain replicating at a very low level until it had replicated to a degree capable of causing clinical meningitis. The woman was treated and in November 2015 it was reported that she had recovered.


title: Western African Ebola virus epidemic

text: In terms of medical literature that are reviews, few articles have been published, such as Shantha, et al. which discusses management of panuveitis and iris heterochromia.


title: Western African Ebola virus epidemic

text: An observational study, done roughly 29 months after the 2007 Bundibugyo outbreak in Uganda, found that long-term sequelae (i.e. consequences) persisted among survivors. Symptoms included eye pain, blurred vision, hearing loss, difficulty swallowing, difficulty sleeping, arthralgias, memory loss or confusion, and "various constitutional symptoms controlling for age and sex".


title: Western African Ebola virus epidemic

text: From August through December 2014, a total of 10 patients with Ebola were treated in US hospitals; of these patients, 8 survived. In March 2015, the CDC interviewed the survivors; they all reported having had at least one adverse symptom during their recovery period. The symptoms ranged from mild (e.g. hair loss) to more severe complications requiring re-hospitalisation or treatment. The most frequently reported symptoms were lethargy or fatigue, joint pain, and hair loss. Sixty-three per cent reported having eye problems including two who were diagnosed with uveitis, 75% reported psychological or cognitive symptoms, and 38% reported neural difficulties. Although most symptoms resolved or improved over time, only one survivor reported complete resolution of all symptoms.


title: Western African Ebola virus epidemic

text: A study published in May 2015 discussed the case of Ian Crozier, a Zimbabwe-born physician and American citizen who became infected with Ebola while he was working at an Ebola treatment centre in Sierra Leone. He was transported to the US and successfully treated at Emory University Hospital. However, after discharge Crozier began to experience symptoms including low back pain, bilateral enthesitis of the Achilles tendon, paresthesias involving his lower legs, and eye pain, which was diagnosed as uveitis. His eye condition worsened and a specimen of aqueous humor obtained from his eye tested positive for Ebola. The authors of the study concluded that "further studies to investigate the mechanisms responsible for the ocular persistence of Ebola and the possible presence of the virus in other immune-privileged sites (e.g., in the central nervous system, gonads, and articular cartilage) are warranted." The authors also noted that 40% of participants in a survey of 85 Ebola survivors in Sierra Leone reported having "eye problems", though the incidence of actual uveitis was unknown.


title: Western African Ebola virus epidemic

text: Another study, which was released in August 2015 looked at the health difficulties reported by survivors. Calling the set of symptoms "post-Ebolavirus disease syndrome", the research found symptoms that included "chronic joint and muscle pain, fatigue, anorexia, hearing loss, blurred vision, headache, sleep disturbances, low mood and short-term memory problems", and suggested the "implementation of specialised health services to treat and follow-up survivors".


title: Western African Ebola virus epidemic

text: In June 2014, it was reported that local authorities did not have the resources to contain the disease, with health centres closing and hospitals becoming overwhelmed. There were also reports that adequate personal protection equipment was not being provided for medical personnel. The Director-General of MSF said: "Countries affected to date simply do not have the capacity to manage an outbreak of this size and complexity on their own. I urge the international community to provide this support on the most urgent basis possible."


title: Western African Ebola virus epidemic

text: In late August, MSF called the situation "chaotic" and the medical response "inadequate." They reported that they had expanded their operations, but couldn't keep up with the rapidly increasing need for assistance, which had forced them to reduce the level of care: "It is not currently possible, for example, to administer intravenous treatments." Calling the situation "an emergency within the emergency", MSF reported that many hospitals had shut down due to lack of staff or fears of the virus among patients and staff, which had left people with other health problems without any care at all. Speaking from a remote region, an MSF worker said that a shortage of protective equipment was making the medical management of the disease difficult and that they had limited capacity to safely bury bodies.


title: Western African Ebola virus epidemic

text: By September, treatment for Ebola patients had become unavailable in some areas. Speaking on 12 September, WHO Director-General, Margaret Chan, said: "In the three hardest hit countries, Guinea, Liberia and Sierra Leone, the number of new cases is moving far faster than the capacity to manage them in the Ebola-specific treatment centres. Today, there is not one single bed available for the treatment of an Ebola patient in the entire country of Liberia." According to a WHO report released on 19 September, Sierra Leone was meeting only 35% of its need for patient beds, while for Liberia it was just 20%.


title: Western African Ebola virus epidemic

text: In early December, the WHO reported that at a national level there were enough beds in treatment facilities to treat and isolate all reported Ebola cases, although their uneven distribution was resulting in serious shortfalls in some areas. Similarly, all affected countries had sufficient and widespread capacity to bury reported deaths; however, because not all deaths were reported, it was possible that the reverse could have been the case in some areas. WHO also reported that every district had access to a laboratory to confirm cases of Ebola within 24 hours of sample collection, and that all three countries had reported that more than 80% of registered contacts associated with known cases of Ebola virus disease were being traced, although contact tracing was still a challenge in areas of intense transmission and those with community resistance.


title: Western African Ebola virus epidemic

text: A number of Ebola Treatment Centres were set up in the area, supported by international aid organisations and staffed by a combination of local and international staff. Each treatment centre is divided into a number of distinct and rigorously separate areas. For patients, there is a triage area, and low- and high-risk care wards. For staff, there are areas for preparation and decontamination. An important part of each centre is an arrangement for safe burial or cremation of bodies, required to prevent further infection. In January 2015, a new treatment and research centre was built by Rusal and Russia in the city of Kindia in Guinea. It is one of the most modern medical centres in Guinea. Also in January, MSF admitted its first patients to a new treatment centre in Kissy, an Ebola hotspot on the outskirts of Freetown, Sierra Leone. The centre has a maternity unit for pregnant women with the virus.


title: Western African Ebola virus epidemic

text: Although the WHO does not advise caring for Ebola patients at home, in some cases it became a necessity when no hospital treatment beds were available. For those being treated at home, the WHO advised informing the local public health authority and acquiring appropriate training and equipment. UNICEF, USAID and Samaritan's Purse began to take measures to provide support for families that were forced to care for patients at home by supplying caregiver kits intended for interim home-based interventions. The kits included protective clothing, hydration items, medicines, and disinfectant, among other items. Even where hospital beds were available, it was debated whether conventional hospitals are the best place to care for Ebola patients, as the risk of spreading the infection is high. In October, the WHO and non-profit partners launched a program in Liberia to move infected people out of their homes into ad hoc centres that could provide rudimentary care. Health facilities with low-quality systems for preventing infection were involved as sites of amplification during viral outbreaks.


title: Western African Ebola virus epidemic

text: The Ebola epidemic caused an increasing demand for protective clothing. A full set of protective clothing includes a suit, goggles, a mask, socks and boots, and an apron. Boots and aprons can be disinfected and reused, but everything else must be destroyed after use. Health workers change garments frequently, discarding gear that has barely been used. This not only takes a great deal of time but also exposes them to the virus because, for those wearing protective clothing, one of the most dangerous moments for contracting Ebola is while suits are being removed.


title: Western African Ebola virus epidemic

text: The protective clothing sets that MSF uses cost about $75 apiece. Staff who have returned from deployments to Western Africa say the clothing is so heavy that it can be worn for only about 40 minutes at a stretch. A physician working in Sierra Leone has said: "After about 30 or 40 minutes, your goggles have fogged up; your socks are completely drenched in sweat. You're just walking in water in your boots. And at that point, you have to exit for your own safety ... Here it takes 20–25 minutes to take off a protective suit and must be done with two trained supervisors who watch every step in a military manner to ensure no mistakes are made, because a slip up can easily occur and of course can be fatal." By October, there were reports that protective outfits were beginning to be in short supply and manufacturers began to increase their production, but the need to find better types of suits has also been raised.
