text: As a result, the 4.2-litre Type 1 generally became the most valuable form of the car. However, as of the end of 2014, the most expensive regular production Jaguar E-Types sold at auction included a 4.2-litre Series 1 roadster, with matching numbers, original paint and interior, under 80,000 original miles, and a history of being in the original buyer's family for 45 years, for $467,000 in 2013, and a 3.8-litre 1961 "flat floor" Series 1, for $528,000 in 2014. Special run racing lightweights go for far more still. For example, a 1963 E-type Lightweight Competition advertised as very original and with much patina (wearing the "factory installed interior and bodywork showing the patina of decades of use," although it was re-painted and has a non-matching numbers - albeit factory provided - engine), one of just twelve that were built, sold for $7,370,000 at the 2017 Scottsdale, Arizona auctions.

text: Being a British-made car of the 1960s, there are some rather rare sub-types of Series 1 E-Types, particularly at the beginning and end of the Series 1 production. For example, the first 500 Series 1 cars had flat floors and external bonnet latches. At the close of the Series 1 production run, there were a small number of cars produced that are identical in every respect to other Series 1 units (including triple SU carbs, button actuated starter, toggle switches, etc.), except that the headlight covers were removed for better illumination. It is not known exactly how many of these Series 1 cars (sometimes referred to as for convenience sake as "Series 1.25," but per Jaguar, Series 1) were produced, but given that 1,508 Series 1 roadsters were produced worldwide for 1967, combined with the fact that these examples were made in just the last several months of Series 1 production, means that these, like the flat floor examples that began the Series 1 production run, are the lowest volume Series 1 variant, save of course for the special lightweights.


title: Jaguar E-Type

text: Including both left and right hand drive examples, a total of 7,828 3.8-litre Series 1 roadsters were built, with 6,749 of the later 4.2-litre Series 1 roadsters having been manufactured.


title: Jaguar E-Type

text: While the 1968 Series 1.5 cars maintained the essential design of the Series 1 models, US emission regulations saw its triple SU carburetors replaced there with twin Zenith-Stromberg units, resulting in a drop in claimed horsepower from 265 to 246 and torque from 283 to 263.


title: Jaguar E-Type

text: Safety and emissions regulations in the North American market resulted in Series 2 and 3 E-Types being fitted with a larger grille, wider wheel arches, and bigger bumpers. And they were also fitted with a bigger radiator and cooling system because the Series 1 were notorious for overheating


title: Jaguar E-Type

text: The New York City Museum of Modern Art recognised the significance of the E-Type's design in 1996 by adding a blue roadster to its permanent design collection, one of only six automobiles to receive the distinction.


title: Jaguar E-Type

text: After the company's success at the Le Mans 24 hr through the 1950s, Jaguar's racing department was given the brief to use D-Type style construction to build a road-going sports car, replacing the XK150.


title: Jaguar E-Type

text: The first prototype (E1A), featured a monocoque design designed in 1957 by William Heynes Technical Director and Chief Engineer, Jaguar's fully independent rear suspension and the well proven "XK" engine.


title: Jaguar E-Type

text: The car was used solely for factory testing and was never formally released to the public. The car was eventually scrapped by the factory.


title: Jaguar E-Type

text: Jaguar's second E-Type concept was E2A which, unlike the E1A, was constructed from a steel chassis with an aluminium body. This car was completed as a racing car as it was thought by Jaguar at the time it would provide a better testing ground. E2A used a 3-litre version of the XK engine with a Lucas fuel injection system.


title: Jaguar E-Type

text: After retiring from the Le Mans 24 hr the car was shipped to America to be used for racing by Jaguar privateer Briggs Cunningham. In 1961, the car returned to Jaguar in England to be used as a test vehicle. Ownership of E2A passed in 1970 to Roger Woodley (Jaguar's customer competition car manager) who took possession on the basis the car not be used for racing. E2A had been possibly scheduled to be scrapped. Roger's wife owned E2A until 2008 when it was offered for sale at Bonham's Quail Auction, where it sold for US$4,957,000.


title: Jaguar E-Type

text: Jaguar unveiled a modern revival of the 1968 E-Type series 1.5 roadster with an all-electric, zero-emission powertrain in September 2017. The vehicle has a 40kWh battery-powered electric motor and can accelerate to 60mph in 5.5 seconds. On a full charge, the vehicle has a range of 168 miles (270 km). The battery pack is designed to fit in the space occupied by the original six-cylinder motor without any modifications, and will fit in any model Jaguar using the same motor. The electric motor replaces the original transmission.


title: Jaguar E-Type

text: In August 2018, Jaguar confirmed it will offer all-electric E-Types for sale starting in summer 2020.. However, this plan was halted in 2019.


title: Jaguar E-Type

text: The Series 1 was introduced, initially for export only, in March 1961. The domestic market launch came four months later in July 1961. The cars at this time used the triple SU carburetted 3.8-litre six-cylinder Jaguar XK6 engine from the XK150S. Earlier built cars utilised external bonnet latches which required a tool to open and had a flat floor design. These cars are rare and more valuable. After that, the floors were dished to provide more leg room and the twin bonnet latches moved to inside the car. The 3.8-litre engine was increased to in October 1964.


title: Jaguar E-Type

text: The 4.2-litre engine produced the same power as the 3.8-litre () and same top speed (), but increased torque 18% from . Acceleration remained pretty much the same and times were around 6.4 seconds for both engines, but maximum power was now reached at 5,400 rpm instead of 5,500 rpm on the 3.8-litre. That all meant better throttle response for drivers that did not want to shift down gears. The 4.2-litre's block was completely redesigned, made longer to accommodate larger bores, and the crankshaft modified to use newer bearings. Other engine upgrades included a new alternator/generator and an electric cooling fan for the radiator.


title: Jaguar E-Type

text: "Autocar" road tested a UK spec E-Type 4.2 fixed head coupé in May 1965. The maximum speed was , the time was 7.6 seconds and the from a standing start took 15.1 seconds. They summarised it as "In its 4.2 guise the E-Type is a fast car (the fastest we have ever tested) and offers just about the easiest way to travel quickly by road.".


title: Jaguar E-Type

text: "Motor" magazine road tested a UK spec E-Type 4.2 fixed head coupé in Oct 1964. The maximum speed was , the 0– time was 7 seconds and the time was 14.9 seconds. They summarised it as "The new 4.2 supersedes the early 3.8 as the fastest car "Motor" has tested. The absurd ease which can be exceeded in a never failed to astonish. of testing confirms that this is still one of the world's outstanding cars".


title: Jaguar E-Type

text: All E-Types featured independent coil spring rear suspension designed and developed by R J Knight with torsion bar front ends, and four wheel disc brakes, in-board at the rear, all were power-assisted. The Coventry engineers spared nothing with regards to high automotive technology in braking. Like several British car builders of the middle and late 1950s, the four-wheel disc brakes were also used in that era by Austin-Healey and MG, putting the British far ahead of Ferrari, Maserati, Alfa Romeo, Porsche, and Mercedes-Benz. Even Lanchester tried an abortive attempt to use copper disc brakes in 1902. Jaguar was one of the first vehicle manufacturers to equip production cars with 4 wheel disc brakes as standard from the XK150 in 1958. The Series 1 (except for late 1967 models) can be recognised by glass-covered headlights (up to 1967), small "mouth" opening at the front, signal lights and tail-lights above bumpers and exhaust tips under the number plate in the rear.


title: Jaguar E-Type

text: 3.8-litre cars have leather-upholstered bucket seats, an aluminium-trimmed centre instrument panel and console (changed to vinyl and leather in 1963), and a Moss four-speed gearbox that lacks synchromesh for first gear ("Moss box") on all except very last cars. 4.2-litre cars have more comfortable seats, improved brakes and electrical systems, and,obviously, an all-synchromesh Jaguar designed four-speed gearbox. 4.2-litre cars also have a badge on the boot proclaiming "Jaguar 4.2 Litre E-Type" (3.8 cars have a simple "Jaguar" badge). Optional extras included chrome spoked wheels and a detachable hard top for the OTS. When leaving the factory the car was originally fitted with Dunlop 6.40 × 15-inch RS5 tyres on 15 × 5K wire wheels (with the rear fitting 15 × 5K½ wheels supplied with 6.50 X15 Dunlop Racing R5 tyres in mind of competition). Later Series One cars were fitted with Dunlop 185 - 15 SP41 or 185 VR 15 Pirelli Cinturato as radial ply tyres.


title: Jaguar E-Type

text: A 2+2 version of the fastback coupé was added in 1966. The 2+2 offered the option of an automatic transmission. The body is longer and the roof angles are different. The roadster and the non 2+2 FHC (Fixed Head Coupé) remained as two-seaters.


title: Jaguar E-Type

text: Less widely known, right at the end of Series 1 production, but prior to the transitional "Series 1½" referred to below, a small number of Series 1 cars were produced with open headlights. These Series 1 cars had their headlights modified by removing the covers and altering the scoops they sit in, but these Series 1 headlights differ in several respects from those later used in the Series 1½ (or 1.5), the main being they are shorter at 143 mm from the Series 1½ at 160 mm. Production dates on these machines vary but in right-hand drive form production has been verified as late as July 1968. They are not "rare" in the sense of the build of the twelve lightweights, but they are certainly uncommon; they were not produced until January 1967 and given the foregoing information that they were produced as late as July 1968, it appears that there must have been an overlap with the Series 1.5 production, which began in August 1967 as model year 1968 models. These calendar year/model year Series 1 E-Types are identical to other 4.2-litre Series 1 examples in every respect except for the open headlights; all other component areas, including the exterior, the interior, and the engine compartment are the same, with the same three SU carburettors, polished aluminium cam covers, centre dash toggle switches, etc.


title: Jaguar E-Type

text: Following the Series 1 there was a transitional series of cars built in 1967–68 as model year 1968 cars, unofficially called "Series 1½." Due to American pressure the new features were not just open headlights, but also different switches (black rocker switches as opposed to the Series 1 toggle switches), de-tuning for emissions (using two Zenith-Stromberg carburettors instead of the original three SUs) for US models, ribbed cam covers painted black except for the top brushed aluminium ribbing, bonnet frames on the OTS that have two bows, and other changes. Series 1½ cars also have twin cooling fans and adjustable seat backs. The biggest change between 1961 and 1967 Series 1 E-Types and the 1968 Series 1.5 was the reduction in the number of carburettors from 3 to just 2 (North America), resulting in a loss in horsepower.


title: Jaguar E-Type

text: Series 2 features were gradually introduced into the Series 1, creating the unofficial Series 1½ cars, but always with the Series 1 body style. A United States federal safety law affecting 1968 model year cars sold in the US was the reason for the lack of headlight covers and change in dash switch design in the "Series 1.5" of 1968. An often overlooked change, one that is often "modified back" to the older style, is the wheel knock-off "nut." US safety law for 1968 models also forbade the winged-spinner knockoff, and any 1968 model year sold in the US (or earlier German delivery cars) should have a hexagonal knockoff nut, to be hammered on and off with the assistance of a special "socket" included with the car from the factory. This hexagonal nut carried on into the later Series 2 and 3. The engine configuration of the US Series 1.5s was the same as is found in the Series 2.


title: Jaguar E-Type

text: An open 3.8-litre car, actually the first such production car to be completed, was tested by the British magazine " Motor" in 1961 and had a top speed of and could accelerate from in 7.1 seconds. A fuel consumption of was recorded. The test car cost £2,097 including taxes.


title: Jaguar E-Type

text: The cars submitted for road test by the motoring journals of the time (1961) such as "Motor", "Autocar" and "Autosport" magazines were prepared by the Jaguar works. This work entailed engine balancing and subtle tuning work such as gas-flowing checking the cylinder heads but otherwise production built engines.


title: Jaguar E-Type

text: Both of the well-known 1961 road test cars: the E-Type coupé Reg. No. 9600 HP and E-Type Convertible Reg. No. 77 RW, were fitted with Dunlop Racing Tyres on test, which had a larger rolling diameter and lower drag coefficient. This goes some way to explaining the maximum speeds that were obtained under ideal test conditions. The maximum safe rev limit for standard 6-cylinder 3.8-litre E-Type engines is 5,500 rpm. The later 4.2-Litre units had a red marking on the rev counter from just 5,000 rpm. Both 3.8 test cars may have approached 6,000 rpm in top gear when on road test, depending on final drive ratio.


title: Jaguar E-Type

text: The Series 2 introduced a number of design changes, largely due to U.S. National Highway Traffic and Safety Administration mandates. The most distinctive exterior feature is the absence of the glass headlight covers, which affected several other imported cars, such as the Citroën DS, as well. Unlike other cars, this step was applied worldwide for the E-Type.


title: Jaguar E-Type

text: Other hallmarks of Series 2 cars are a wrap-around rear bumper, larger front indicators and tail lights re-positioned below the bumpers, and an enlarged grille and twin electric fans to aid cooling.


title: Jaguar E-Type

text: Additional U.S.-inspired changes included a steering lock which moved the ignition switch to the steering column, replacing the dashboard mounted ignition and push button starter, the symmetrical array of metal toggle switches replaced with plastic rockers, and a collapsible steering column to absorb impact in the event of an accident. New seats allowed the fitment of head restraints, as required by U.S. law beginning in 1969.


title: Jaguar E-Type

text: The engine is easily identified visually by the change from smooth polished cam covers to a more industrial "ribbed" appearance. It was de-tuned in the US with twin two-barrel Strombergs replacing three SUs. Combined with larger valve clearances horsepower was reduced from 265 to 246 and torque from 283 to 263.


title: Jaguar E-Type

text: The E-Type Series 3 was introduced in 1971, with a new 5.3 L Jaguar V12 engine, uprated brakes and standard power steering. An automatic transmission, wire wheels and air conditioning were available options. The V12 was equipped with four Zenith carburettors, and as introduced produced a claimed 203 kW (272 hp), more torque, and a 0–60 mph acceleration of less than seven seconds. The short wheelbase FHC body style was discontinued, with the Series 3 available only as a convertible and 2+2 coupé. Fifty Series 3 E-Types were constructed as end of model commemorative cars. They featured black exteriors, cinnamon upholstery and commemorative plaques on the glove box (apart from a single green car that Jaguar painted for a long-standing customer). The final production E-Type OTS Roadster was built in June 1974.


title: Jaguar E-Type

text: The new longer wheelbase offered significantly more room in all directions. The Series 3 is easily identifiable by the large cross-slatted front grille, flared wheel arches, wider tyres, four exhaust tips and a badge on the rear that proclaims it to be a V12. The first published road test of the series 3 was in Jaguar Driver, the club magazine of the Jaguar Drivers' Club, the only owners club to be officially sanctioned by Sir William Lyons and Jaguar themselves. The road test of a car provided by Jaguar was published ahead of all the national and international magazines.


title: Jaguar E-Type

text: Cars for the US market were fitted with large projecting rubber bumper over-riders (in 1973 these were on front, in 1974 both front and rear) to meet local impact regulations, but those on European models were considerably smaller. US models also have side indicator repeats on the front wings. There were also a very limited number of six-cylinder Series 3 E-Types built. These were featured in the initial sales procedure but the lack of demand stopped their production. The V12 Open Two Seater and V12 2+2 were factory fitted with Dunlop E70VR − 15-inch tyres on 15 × 6K wire or solid wheels.


title: Jaguar E-Type

text: Two limited production E-Type variants were made as test beds, the low drag coupé and lightweight E-Type, both of which were raced:


title: Jaguar E-Type

text: Shortly after the introduction of the E-Type, Jaguar wanted to investigate the possibility of building a car more in the spirit of the D-Type racer from which elements of the E-Type's styling and design were derived. One car was built to test the concept designed as a coupé. Unlike the steel production E-Types, the LDC used lightweight aluminium. Malcolm Sayer retained the original tub with lighter outer panels riveted and glued to it. The front steel sub frame remained intact, the windshield was given a more pronounced slope, and the rear hatch was welded shut. Rear brake cooling ducts appeared next to the rear windows, and the interior trim was discarded, with only insulation around the transmission tunnel. With the exception of the windscreen, all cockpit glass was perspex. A tuned version of Jaguar's 3.8-litre engine with a wide-angle cylinder head design tested on the D-Type racers was used.


title: Jaguar E-Type

text: The only test bed car was completed in summer of 1962 but was sold a year later to Jaguar racing driver Dick Protheroe. Since then it has passed through the hands of several collectors on both sides of the Atlantic and is now believed to reside in the private collection of the current Viscount Cowdray.


title: Jaguar E-Type

text: Peter Lindner, the Jaguar distributor in Germany, had his Lightweight modified by competition department to include the low drag roof and rear panels as part of an effort to win the GT class at Le Mans. Lindner's car was more than a match for the Ferrari 250 GTO but mechanical problems forced it out of the race. Lindner was later killed in a racing accident that demolished his car, which has recently been restored.


title: Jaguar E-Type

text: Jaguar waited too long before committing to a racing program in earnest and what could have been a world champion in 1962 was not competitive by 1965.


title: Jaguar E-Type

text: In some ways, this was an evolution of the low drag coupé. It made extensive use of aluminium alloy metal, in the body panels and other components. However, with at least one exception, it remained an open-top car in the spirit of the D-Type to which this car is a more direct successor than the production E-Type which is more of a GT than a sports car. The cars used an aluminium block tuned version of the production 3.8-litre Jaguar engine with output rather than the 265 bhp (198 kW) produced by the "ordinary" version. Factory-built lightweights were homologated by Jaguar with three 45DCOE Weber carburettors in addition to a Lucas mechanical fuel injection system. Early cars were fitted with a close-ratio version of the four speed E-Type gearbox, with some later cars being fitted with a ZF five speed gearbox.


title: Jaguar E-Type

text: The cars were entered in various races but, unlike the C-Type and D-Type racing cars, they did not win at Le Mans or Sebring but were reasonably successful in private hands and in smaller races.


title: Jaguar E-Type

text: One lightweight was modified by Jaguar competition department into a low drag coupé (the Lindner/Nöcker car).


title: Jaguar E-Type

text: On 14 May 2014, Jaguar's Heritage Business announced it would be building the six 'remaining' lightweights. The original run of lightweights was meant to be 18 vehicles; however only 12 were built. The new cars, using the unused chassis codes, will be hand built to exactly the same specification as the originals. Availability was prioritised for established collectors of Jaguars, with a focus on those who have an interest in historic race cars.


title: Jaguar E-Type

text: The Jaguar E-Type was very successful in SCCA Production sports car racing with Group 44 and Bob Tullius taking the B-Production championship with a Series-3 V12 racer in 1975. A few years later, Gran-Turismo Jaguar from Cleveland Ohio campaigned a 4.2-litre six-cylinder FHC racer in SCCA production series, and in 1980 won the National Championship in the SCCA C-Production Class, defeating a fully funded factory Nissan Z-car team with Paul Newman.

text: In 2013, the Jaguar E-Type featured on a "British Auto Legends" postage stamp issued by the Royal Mail.


title: 2009 swine flu pandemic

text: The 2009 swine flu pandemic, caused by the H1N1 influenza virus and declared by the World Health Organization (WHO) from June 2009 to August 2010, is the third recent flu pandemic involving the H1N1 virus (the first being the 1918–1920 Spanish flu pandemic and the second being the 1977 Russian flu). The first two cases were discovered independently in the United States in April 2009. The virus appeared to be a new strain of H1N1 that resulted from a previous triple reassortment of bird, swine, and human flu viruses which further combined with a Eurasian pig flu virus, leading to the term "swine flu".


title: 2009 swine flu pandemic

text: Some studies estimated that the real number of cases including asymptomatic and mild cases could be 700 million to 1.4 billion people—or 11 to 21 percent of the global population of 6.8 billion at the time. The lower value of 700 million is more than the 500 million people estimated to have been infected by the Spanish flu pandemic. However, the Spanish flu infected approximately a third of the world population at the time, a much higher proportion.


title: 2009 swine flu pandemic

text: The number of lab-confirmed deaths reported to the WHO is 18,449 and is widely considered a gross underestimate. The WHO collaborated with the US Centers for Disease Control and Prevention (USCDC) and Netherlands Institute for Health Services Research (NIVEL) to produce two independent estimates of the influenza deaths that occurred during the global pandemic using two distinct methodologies. The 2009 H1N1 flu pandemic is estimated to have actually caused about 284,000 (range from 150,000 to 575,000) excess deaths by the WHO-USCDC study and 148,000–249,000 excess respiratory deaths by the WHO-NIVEL study. A study done in September 2010 showed that the risk of serious illness resulting from the 2009 H1N1 flu was no higher than that of the yearly seasonal flu. For comparison, the WHO estimates that 250,000 to 500,000 people die of seasonal flu annually. However, the H1N1 influenza epidemic in 2009 resulted in a large increase in the number of new cases of narcolepsy.


title: 2009 swine flu pandemic

text: Unlike most strains of influenza, the pandemic H1N1/09 virus did not disproportionately infect adults older than 60 years; this was an unusual and characteristic feature of the H1N1 pandemic. Even in the case of previously healthy people, a small percentage develop pneumonia or acute respiratory distress syndrome (ARDS). This manifests itself as increased breathing difficulty and typically occurs three to six days after initial onset of flu symptoms. The pneumonia caused by flu can be either direct viral pneumonia or a secondary bacterial pneumonia. A November 2009 "New England Journal of Medicine" article recommended that flu patients whose chest X-ray indicates pneumonia receive both antivirals and antibiotics. In particular, it is a warning sign if a child seems to be getting better and then relapses with high fever, as this relapse may be bacterial pneumonia.


title: 2009 swine flu pandemic

text: The World Health Organization uses the term "(H1N1) 2009 pandemic" when referring to the event, and officially adopted the name "A(H1N1)pdm09" for the virus in 2010, after the conclusion of the pandemic.


title: 2009 swine flu pandemic

text: and officials. Labels like "H1N1 flu", "Swine flu", "Mexican flu", and variations thereof were typical. Criticism centered on how these names may confuse or mislead the public. It was argued that the names were overly technical (e.g. "H1N1"), incorrectly implying that the disease is caused by contact with pigs or pig products, or provoking stigmatization against certain communities (e.g. "Mexican"). Some academics of the time asserted there is nothing wrong with such names, while research published years later (in 2013) concluded that Mexican Americans and Latino Americans had indeed been stigmatized due to the frequent use of term "Mexican flu" in the news media.


title: 2009 swine flu pandemic

text: Official entities adopted terms with varying consistency over the course of the pandemic. The CDC used names like "novel influenza A (H1N1)" or "2009 H1N1 flu". The Netherlands National Institute for Public Health and the Environment used the term "Pig Flu" early on. Officials in Taiwan suggested use of the names "H1N1 flu" or "new flu". The World Organization for Animal Health, an IGO based in Europe, proposed the name "North American influenza". The European Commission adopted the term "novel flu virus". Officials in Israel and South Korea briefly considered adoption of the name "Mexican virus" due to concern about the use of the word "swine". In Israel, objections stemmed from sensitivity to religious restrictions on eating pork in the Jewish and Muslim populations, in South Korea, concerns were influenced by the importance of pork and domestic pigs.


title: 2009 swine flu pandemic

text: As terminology changed to deal with these and other such issues, further criticism was made that the situation was unnecessarily confusing. For example, the news department at the journal "Science" produced an article with the humorous title "Swine Flu Names Evolving Faster Than Swine Flu Itself".


title: 2009 swine flu pandemic

text: Analysis of the genetic divergence of the virus in samples from different cases indicated that the virus jumped to humans in 2008, probably after June, and not later than the end of November, likely around September 2008. The research also indicated the virus had been latent in pigs for several months prior to the outbreak, suggesting a need to increase agricultural surveillance to prevent future outbreaks. In 2009, U.S. agricultural officials speculated, although emphasizing that there was no way to prove their hypothesis, that "contrary to the popular assumption that the new swine flu pandemic arose on factory farms in Mexico, [the virus] most likely emerged in pigs in Asia, but then traveled to North America in a human." However, a subsequent report by researchers at the Mount Sinai School of Medicine in 2016 found that the 2009 H1N1 virus likely originated from pigs in a very small region of central Mexico.


title: 2009 swine flu pandemic

text: Initially called an "outbreak", widespread H1N1 infection was first recognized in the state of Veracruz, Mexico, with evidence that the virus had been present for months before it was officially called an "epidemic". The Mexican government closed most of Mexico City's public and private facilities in an attempt to contain the spread of the virus; however, it continued to spread globally, and clinics in some areas were overwhelmed by infected people. The new virus was first isolated in late April by American and Canadian laboratories from samples taken from people with flu in Mexico, Southern California, and Texas. Soon the earliest known human case was traced to a case from 9March 2009 in a 5-year-old boy in La Gloria, Mexico, a rural town in Veracruz. In late April, the World Health Organization (WHO) declared its first ever "public health emergency of international concern," or PHEIC, and in June, the WHO and the U.S. CDC stopped counting cases and declared the outbreak a pandemic.


title: 2009 swine flu pandemic

text: Despite being informally called "swine flu", the H1N1 flu virus cannot be spread by eating pork products; similar to other influenza viruses, it is typically contracted by person to person transmission through respiratory droplets. Symptoms usually last 4–6 days. Antivirals (oseltamivir or zanamivir) were recommended for those with more severe symptoms or those in an at-risk group.


title: 2009 swine flu pandemic

text: The pandemic began to taper off in November 2009, and by May 2010, the number of cases was in steep decline. On 10 August 2010, the Director-General of the WHO, Margaret Chan, announced the end of the H1N1 pandemic and announced that the H1N1 influenza event had moved into the post-pandemic period. According to WHO statistics (as of July 2010), the virus had killed more than 18,000 people since it appeared in April 2009; however, they state that the total mortality (including deaths unconfirmed or unreported) from the H1N1 strain is "unquestionably higher". Critics claimed the WHO had exaggerated the danger, spreading "fear and confusion" rather than "immediate information". The WHO began an investigation to determine whether it had "frightened people unnecessarily". A flu follow-up study done in September 2010, found that "the risk of most serious complications was not elevated in adults or children." In a 5August 2011 "PLOS ONE" article, researchers estimated that the 2009 H1N1 global infection rate was 11% to 21%, lower than what was previously expected. However, by 2012, research showed that as many as 579,000 people could have been killed by the disease, as only those fatalities confirmed by laboratory testing were included in the original number, and meant that many without access to health facilities went uncounted. The majority of these deaths occurred in Africa and Southeast Asia. Experts, including the WHO, have agreed that an estimated 284,500 people were killed by the disease, much higher than the initial death toll.


title: 2009 swine flu pandemic

text: The symptoms of H1N1 flu are similar to those of other influenzas, and may include fever, cough (typically a "dry cough"), headache, dizziness, sneezing, muscle or joint pain, sore throat, chills, fatigue, and runny nose. Diarrhea, vomiting, and neurological problems have also been reported in some cases. People at higher risk of serious complications include people over 65, children younger than 5, children with neurodevelopmental conditions, pregnant women (especially during the third trimester), and people of any age with underlying medical conditions, such as asthma, diabetes, obesity, heart disease, or a weakened immune system (e.g., taking immunosuppressive medications or infected with HIV). More than 70% of hospitalizations in the U.S. have been people with such underlying conditions, according to the CDC.

text: In September 2009, the CDC reported that the H1N1 flu "seems to be taking a heavier toll among chronically ill children than the seasonal flu usually does". Through 8August 2009, the CDC had received 36 reports of pediatric deaths with associated influenza symptoms and laboratory-confirmed pandemic H1N1 from state and local health authorities within the United States, with 22 of these children having neurodevelopmental conditions such as cerebral palsy, muscular dystrophy, or developmental delays. "Children with nerve and muscle problems may be at especially high risk for complications because they cannot cough hard enough to clear their airways". From 26 April 2009, to 13 February 2010, the CDC had received reports of the deaths of 277 children with laboratory-confirmed 2009 influenza A (H1N1) within the United States.

text: The World Health Organization reports that the clinical picture in severe cases is strikingly different from the disease pattern seen during epidemics of seasonal influenza. While people with certain underlying medical conditions are known to be at increased risk, many severe cases occur in previously healthy people. In severe cases, patients generally begin to deteriorate around three to five days after symptom onset. Deterioration is rapid, with many patients progressing to respiratory failure within 24 hours, requiring immediate admission to an intensive care unit. Upon admission, most patients need immediate respiratory support with mechanical ventilation.


title: 2009 swine flu pandemic

text: Most complications have occurred among previously unhealthy individuals, with obesity and respiratory disease as the strongest risk factors. Pulmonary complications are common. Primary influenza pneumonia occurs most commonly in adults and may progress rapidly to acute lung injury requiring mechanical ventilation. Secondary bacterial infection is more common in children. "Staphylococcus aureus", including methicillin-resistant strains, is an important cause of secondary bacterial pneumonia with a high mortality rate; "Streptococcus pneumoniae" is the second most important cause of secondary bacterial pneumonia for children and primary for adults. Neuromuscular and cardiac complications are unusual but may occur.

text: A United Kingdom investigation of risk factors for hospitalisation and poor outcome with pandemic A/H1N1 influenza looked at 631 patients from 55 hospitals admitted with confirmed infection from May through September 2009. 13% were admitted to a high dependency or intensive care unit and 5% died; 36% were aged <16 years and 5% were aged ≥65 years. Non-white and pregnant patients were over-represented. 45% of patients had at least one underlying condition, mainly asthma, and 13% received antiviral drugs before admission. Of 349 with documented chest x-rays on admission, 29% had evidence of pneumonia, but bacterial co-infection was uncommon. Multivariate analyses showed that physician-recorded obesity on admission and pulmonary conditions other than asthma or chronic obstructive pulmonary disease (COPD) were associated with a severe outcome, as were radiologically confirmed pneumonia and a raised C-reactive protein (CRP) level (≥. 59% of all in-hospital deaths occurred in previously healthy people.


title: 2009 swine flu pandemic

text: Fulminant (sudden-onset) myocarditis has been linked to infection with H1N1, with at least four cases of myocarditis confirmed in patients also infected with A/H1N1. Three out of the four cases of H1N1-associated myocarditis were classified as fulminant, and one of the patients died.


title: 2009 swine flu pandemic

text: Also, there appears to be a link between severe A/H1N1 influenza infection and pulmonary embolism. In one report, five out of 14 patients admitted to the intensive care unit with severe A/H1N1 infection were found to have pulmonary emboli.


title: 2009 swine flu pandemic

text: An article published in "JAMA" in September 2010 challenged previous reports and stated that children infected in the 2009 flu pandemic were no more likely to be hospitalised with complications or get pneumonia than those who catch seasonal strains. Researchers found that about 1.5% of children with the H1N1 swine flu strain were hospitalised within 30 days, compared with 3.7% of those sick with a seasonal strain of H1N1 and 3.1% with an H3N2 virus.


title: 2009 swine flu pandemic

text: Confirmed diagnosis of pandemic H1N1 flu requires testing of a nasopharyngeal, nasal, or oropharyngeal tissue swab from the patient. Real-time RT-PCR is the recommended test as others are unable to differentiate between pandemic H1N1 and regular seasonal flu. However, most people with flu symptoms do not need a test for pandemic H1N1 flu specifically, because the test results usually do not affect the recommended course of treatment. The U.S. CDC recommend testing only for people who are hospitalized with suspected flu, pregnant women, and people with weakened immune systems. For the mere diagnosis of influenza and not pandemic H1N1 flu specifically, more widely available tests include rapid influenza diagnostic tests (RIDT), which yield results in about 30 minutes, and direct and indirect immunofluorescence assays (DFA and IFA), which take 2–4 hours. Due to the high rate of RIDT false negatives, the CDC advises that patients with illnesses compatible with novel influenza A (H1N1) virus infection but with negative RIDT results should be treated empirically based on the level of clinical suspicion, underlying medical conditions, severity of illness, and risk for complications, and if a more definitive determination of infection with influenza virus is required, testing with rRT-PCR or virus isolation should be performed. The use of RIDTs has been questioned by researcher Paul Schreckenberger of the Loyola University Health System, who suggests that rapid tests may actually pose a dangerous public health risk. Nikki Shindo of the WHO has expressed regret at reports of treatment being delayed by waiting for H1N1 test results and suggests, "[D]octors should not wait for the laboratory confirmation but make diagnosis based on clinical and epidemiological backgrounds and start treatment early."


title: 2009 swine flu pandemic

text: On 22 June 2010, the CDC announced a new test called the "CDC Influenza 2009 A (H1N1)pdm Real-Time RT-PCR Panel (IVD)". It uses a molecular biology technique to detect influenza A viruses and specifically the 2009 H1N1 virus. The new test will replace the previous real-time RT-PCR diagnostic test used during the 2009 H1N1 pandemic, which received an emergency use authorization from the U.S. Food and Drug Administration in April 2009. Tests results are available in four hours and are 96% accurate.


title: 2009 swine flu pandemic

text: The virus was found to be a novel strain of influenza for which existing vaccines against seasonal flu provided little protection. A study at the U.S. Centers for Disease Control and Prevention published in May 2009 found that children had no preexisting immunity to the new strain but that adults, particularly those older than 60, had some degree of immunity. Children showed no cross-reactive antibody reaction to the new strain, adults aged 18 to 60 had 6–9%, and older adults 33%. While it has been thought that these findings suggest the partial immunity in older adults may be due to previous exposure to similar seasonal influenza viruses, a November 2009 study of a rural unvaccinated population in China found only a 0.3% cross-reactive antibody reaction to the H1N1 strain, suggesting that previous vaccinations for seasonal flu and not exposure may have resulted in the immunity found in the older U.S. population.


title: 2009 swine flu pandemic

text: Analyses of the genetic sequences of the first isolates, promptly shared on the GISAID database according to Nature and WHO, soon determined that the strain contains genes from five different flu viruses: North American swine influenza, North American avian influenza, human influenza, and two swine influenza viruses typically found in Asia and Europe. Further analysis has shown that several proteins of the virus are most similar to strains that cause mild symptoms in humans, leading virologist Wendy Barclay to suggest on 1May 2009, that the initial indications are that the virus was unlikely to cause severe symptoms for most people.


title: 2009 swine flu pandemic

text: The virus was less lethal than previous pandemic strains and killed about 0.01–0.03% of those infected; the 1918 influenza was about one hundred times more lethal and had a case fatality rate of 2–3%. By 14 November 2009, the virus had infected one in six Americans with 200,000 hospitalisations and 10,000 deaths—as many hospitalizations and fewer deaths than in an average flu season overall, but with much higher risk for those under 50. With deaths of 1,100 children and 7,500 adults 18 to 64, these figures were deemed "much higher than in a usual flu season" during the pandemic.


title: 2009 swine flu pandemic

text: In June 2010, scientists from Hong Kong reported discovery of a new swine flu virus: a hybrid of the pandemic H1N1 virus and viruses previously found in pigs. It was the first report of a reassortment of the pandemic virus, which in humans had been slow to evolve. Nancy Cox, head of the influenza division at the U.S. Centers for Disease Control and Prevention, has said, "This particular paper is extremely interesting because it demonstrates for the first time what we had worried about at the very onset of the pandemic, and that is that this particular virus, when introduced into pigs, could reassort with the resident viruses in pigs and we would have new gene constellations. And bingo, here we are." Pigs have been termed the mixing vessel of flu because they can be infected both by avian flu viruses, which rarely directly infect people, and by human viruses. When pigs become simultaneously infected with more than one virus, the viruses can swap genes, producing new variants which can pass to humans and sometimes spread amongst them. "Unlike the situation with birds and humans, we have a situation with pigs and humans where there's a two-way street of exchange of viruses. With pigs it's very much a two-way street."


title: 2009 swine flu pandemic

text: Spread of the H1N1 virus is thought to occur in the same way that seasonal flu spreads. Flu viruses are spread mainly from person to person through coughing or sneezing by people with influenza. Sometimes people may become infected by touching something—such as a surface or object—with flu viruses on it and then touching their face.


title: 2009 swine flu pandemic

text: The basic reproduction number (the average number of other individuals whom each infected individual will infect, in a population which has no immunity to the disease) for the 2009 novel H1N1 is estimated to be 1.75. A December 2009 study found that the transmissibility of the H1N1 influenza virus in households is lower than that seen in past pandemics. Most transmissions occur soon before or after the onset of symptoms.


title: 2009 swine flu pandemic

text: The H1N1 virus has been transmitted to animals, including swine, turkeys, ferrets, household cats, at least one dog, and a cheetah.


title: 2009 swine flu pandemic

text: Because the H1N1 vaccine was initially in short supply in the U.S., the CDC recommended that initial doses should go to priority groups such as pregnant women, people who live with or care for babies under six months old, children six months to four years old and health-care workers. In the UK, the NHS recommended vaccine priority go to people over six months old who were clinically at risk for seasonal flu, pregnant women and households of people with compromised immunity.


title: 2009 swine flu pandemic

text: Although it was initially thought that two injections would be required, clinical trials showed that the new vaccine protected adults "with only one dose instead of two;" thus the limited vaccine supplies would go twice as far as had been predicted. Health officials worldwide were also concerned because the virus was new and could easily mutate and become more virulent, even though most flu symptoms were mild and lasted only a few days without treatment. Officials also urged communities, businesses, and individuals to make contingency plans for possible school closures, multiple employee absences for illness, surges of patients in hospitals, and other effects of potentially widespread outbreaks. Disaster response organizations such as Direct Relief helped by providing protective items to clinical workers to help them stay healthy throughout flu season.


title: 2009 swine flu pandemic

text: In February 2010, the CDC's Advisory Committee on Immunization Practices voted for "universal" flu vaccination in the U.S. to include all people over six months of age. The 2010–2011 vaccine will protect against the 2009 H1N1 pandemic virus and two other flu viruses.


title: 2009 swine flu pandemic

text: On 27 April 2009, the European Union health commissioner advised Europeans to postpone nonessential travel to the United States or Mexico. This followed the discovery of the first confirmed case in Spain.<ref name="Guardian 27/4"></ref> On 6May 2009, the Public Health Agency of Canada announced that their National Microbiology Laboratory (NML) had mapped the genetic code of the swine flu virus, the first time that had been done. In the U.K., the National Health Service launched a website, the National Pandemic Flu Service, allowing patients to self-assess and get an authorisation number for antiviral medication. The system was expected to reduce the burden on general practitioners.


title: 2009 swine flu pandemic

text: U.S. officials observed that six years of concern about H5N1 avian flu did much to prepare for the current H1N1 outbreak, noting that after H5N1 emerged in Asia, ultimately killing about 60% of the few hundred people infected over the years, many countries took steps to try to prevent any similar crisis from spreading further. The CDC and other U.S. governmental agencies used the summer lull to take stock of the United States response to H1N1 flu and attempt to patch any gaps in the public health safety net before flu season started in early autumn. Preparations included planning a second influenza vaccination program in addition to the one for seasonal flu, and improving coordination between federal, state, and local governments and private health providers. On 24 October 2009, U.S. President Obama declared swine flu a national emergency, giving Secretary of Health and Human Services Kathleen Sebelius authority to grant waivers to requesting hospitals from usual federal requirements.


title: 2009 swine flu pandemic

text: By 19 November 2009, doses of vaccine had been administered in over 16 countries. A 2009 review by the U.S. National Institutes of Health (NIH) concluded that the 2009 H1N1 vaccine has a safety profile similar to that of the seasonal vaccine.


title: 2009 swine flu pandemic

text: In 2011, a study from the US Flu Vaccine Effectiveness Network estimated the overall effectiveness of all pandemic H1N1 vaccines at 56%. A CDC study released 28 January 2013, estimated that the Pandemic H1N1 vaccine saved roughly 300 lives and prevented about a million illnesses in the US. The study concluded that had the vaccination program started two weeks earlier, close to 60% more cases could have been prevented. The study was based on an effectiveness in preventing cases, hospitalizations, and deaths of 62% for all subgroups except people over 65, for whom the effectiveness was estimated at 43%. The effectiveness was based on European and Asian studies and expert opinion. The delay in vaccine administration demonstrated the shortcomings of the world's capacity for vaccine-production, as well as problems with international distribution. Some manufacturers and wealthy countries had concerns regarding liability and regulations, as well as the logistics of transporting, storing, and administering vaccines to be donated to poorer countries.


title: 2009 swine flu pandemic

text: In January 2010, Wolfgang Wodarg, a German deputy who trained as a physician and chaired the health committee at the Council of Europe, claimed that major firms had organized a "campaign of panic" to put pressure on the World Health Organization (WHO) to declare a "false pandemic" to sell vaccines. Wodarg said the WHO's "false pandemic" flu campaign is "one of the greatest medicine scandals of the century". He said that the "false pandemic" campaign began in May 2009 in Mexico City, when a hundred or so "normal" reported influenza cases were declared to be the beginning of a threatening new pandemic, although he said there was little scientific evidence for it. Nevertheless, he argued that the WHO, "in cooperation with some big pharmaceutical companies and their scientists, re-defined pandemics," removing the statement that "an enormous amount of people have contracted the illness or died" from its existing definition and replacing it by stating simply that there has to be a virus, spreading beyond borders and to which people have no immunity.


title: 2009 swine flu pandemic

text: The WHO responded by stating that they take their duty to provide independent advice seriously and guarded against interference from outside interests. Announcing a review of the WHO's actions, spokeswoman Fadela Chaib stated: "Criticism is part of an outbreak cycle. We expect and indeed welcome criticism and the chance to discuss it". The WHO also stated on their website that "The world is going through a real pandemic. The description of it as a fake is wrong and irresponsible". In March 2010, the Council of Europe launched an enquiry into "the influence of the pharmaceutical companies on the global swine flu campaign", and a preliminary report was in preparation.


title: 2009 swine flu pandemic

text: On 12 April 2010, Keiji Fukuda, the WHO's top influenza expert, stated that the system leading to the declaration of a pandemic led to confusion about H1N1 circulating around the world and he expressed concern that there was a failure to communicate in regard to uncertainties about the new virus, which turned out to be not as deadly as feared. WHO Director-General Margaret Chan appointed 29 flu experts from outside the organization to conduct a review of WHO's handling of the H1N1 flu pandemic. She told them, "We want a frank, critical, transparent, credible and independent review of our performance."


title: 2009 swine flu pandemic

text: In June 2010, Fiona Godlee, editor-in-chief of the "BMJ", published an editorial which criticised the WHO, saying that an investigation had disclosed that some of the experts advising WHO on the pandemic had financial ties with drug companies which were producing antivirals and vaccines. Margaret Chan, Director-General of the WHO, replied stating, "Without question, the "BMJ" feature and editorial will leave many readers with the impression that WHO's decision to declare a pandemic was at least partially influenced by a desire to boost the profits of the pharmaceutical industry. The bottom line, however, is that decisions to raise the level of pandemic alert were based on clearly defined virological and epidemiological criteria. It is hard to bend these criteria, no matter what the motive".


title: 2009 swine flu pandemic

text: On 7 May 2009, the WHO stated that containment was not feasible and that countries should focus on mitigating the effect of the virus. They did not recommend closing borders or restricting travel. On 26 April 2009, the Chinese government announced that visitors returning from flu-affected areas who experienced flu-like symptoms within two weeks would be quarantined.


title: 2009 swine flu pandemic

text: U.S. airlines had made no major changes as of the beginning of June 2009, but continued standing practices which include looking for passengers with symptoms of flu, measles or other infections, and relying on in-flight air filters to ensure that aircraft were sanitised. Masks were not generally provided by airlines and the CDC did not recommend that airline crews wear them. Some non-U.S. airlines, mostly Asian, including Singapore Airlines, China Eastern Airlines, China Southern Airlines, Cathay Pacific and Aeromexico, took measures such as stepping up cabin cleaning, installing state-of-the-art air filters and allowing in-flight staff to wear face masks.


title: 2009 swine flu pandemic

text: According to studies conducted in Australia and Japan, screening individuals for influenza symptoms at airports during the 2009 H1N1 outbreak was not an effective method of infection control.


title: 2009 swine flu pandemic

text: U.S. government officials were especially concerned about schools because the H1N1 flu virus appeared to disproportionately affect young and school-age people, between six months and 24 years of age.


title: 2009 swine flu pandemic

text: The H1N1 outbreak led to numerous precautionary school closures in some areas. Rather than closing schools, the CDC recommended that students and school workers with flu symptoms should stay home for either seven days total, or until 24 hours after symptoms subsided, whichever was longer. The CDC also recommended that colleges should consider suspending fall 2009 classes if the virus began to cause severe illness in a significantly larger share of students than the previous spring. They also urged schools to suspend rules, such as penalties for late papers or missed classes or requirements for a doctor's note, to enforce "self-isolation" and prevent students from venturing out while ill; schools were advised to set aside a room for people developing flu-like symptoms while they waited to go home and to have ill students or staff and those caring for them use face masks.


title: 2009 swine flu pandemic

text: In California, school districts and universities were on alert and worked with health officials to launch education campaigns. Many planned to stockpile medical supplies and discuss worst-case scenarios, including plans to provide lessons and meals for low-income children in case elementary and secondary schools closed. University of California campuses stockpiled supplies, from paper masks and hand sanitizer to food and water. To help prepare for contingencies, University of Maryland School of Medicine professor of pediatrics James C. King Jr. suggested that every county should create an "influenza action team" to be run by the local health department, parents, and school administrators. By 28 October 2009, about 600 schools in the United States had been temporarily closed, affecting over 126,000 students in 19 states.


title: 2009 swine flu pandemic

text: Fearing a worst-case scenario, the U.S. Department of Health and Human Services (HHS), the Centers for Disease Control and Prevention and the Department of Homeland Security (DHS) developed updated guidance and a video for employers to use as they developed plans to respond to the H1N1 outbreak. The guidance suggested that employers consider and communicate their objectives, such as reducing transmission among staff, protecting people who are at increased risk of influenza-related complications from becoming infected, maintaining business operations, and minimising adverse effects on other entities in their supply chains.


title: 2009 swine flu pandemic

text: The CDC estimated that as much as 40% of the workforce might be unable to work at the peak of the pandemic due to the need for many healthy adults to stay home and care for an ill family member, and advised that individuals should have steps in place should a workplace close down or a situation arise that requires remote work. The CDC further advised that persons in the workplace should stay home sick for seven days after getting the flu, or 24 hours after symptoms end, whichever is longer.


title: 2009 swine flu pandemic

text: The U.S. CDC did not recommend the use of face masks or respirators in non-health care settings, such as schools, workplaces, or public places, with a few exceptions: people who were ill with the virus when around other people, and people who were at risk for severe illness while caring for someone with the flu. There was some disagreement about the value of wearing face masks, as some experts feared that masks may have given people a false sense of security and should not have replaced other standard precautions.


title: 2009 swine flu pandemic

text: Yukihiro Nishiyama, professor of virology at Nagoya University's School of Medicine, commented that the masks are "better than nothing, but it's hard to completely block out an airborne virus since it can easily slip through the gaps".


title: 2009 swine flu pandemic

text: According to mask manufacturer 3M, masks will filter out particles in industrial settings, but "there are no established exposure limits for biological agents such as swine flu virus". However, despite the lack of evidence of effectiveness, the use of such masks is common in Asia.


title: 2009 swine flu pandemic

text: During the height of the fear of a pandemic, some countries initiated or threatened to initiate quarantines of foreign visitors suspected of having or being in contact with others who may have been infected. In May 2009, the Chinese government confined 21 U.S. students and three teachers to their hotel rooms. As a result, the US State Department issued a travel alert about China's anti-flu measures and warned travellers against travelling to China if ill. In Hong Kong, an entire hotel was quarantined with 240 guests; Australia ordered a cruise ship with 2,000 passengers to stay at sea because of a swine flu threat. Egyptian Muslims who went on the annual pilgrimage to Mecca risked being quarantined upon their return. Russia and Taiwan said they would quarantine visitors with fevers who come from areas where the flu was present. Japan quarantined 47 airline passengers in a hotel for a week in mid-May, then in mid-June India suggested pre-screening "outbound" passengers from countries thought to have a high rate of infection.


title: 2009 swine flu pandemic

text: The pandemic virus is a type of swine influenza, derived originally from a strain which lived in pigs, and this origin gave rise to the common name of "swine flu". This term is widely used by mass media, though the Paris-based World Organisation for Animal Health as well as industry groups such as the U.S. National Pork Board, the American Meat Institute, and the Canadian Pork Council objected to widespread media use of the name "swine flu" and suggested it should be called "North American flu" instead, while the World Health Organization switched its designation from "swine influenza" to "influenza A (H1N1)" in late April 2009. The virus has been found in U.S. hogs, and Canadian as well as in hogs in Northern Ireland, Argentina, and Norway. Leading health agencies and the United States Secretary of Agriculture have stressed that eating properly cooked pork or other food products derived from pigs will not cause flu. Nevertheless, on 27 April Azerbaijan imposed a ban on the importation of animal husbandry products from the entire Americas. The Indonesian government also halted the importation of pigs and initiated the examination of pigs in Indonesia. The Egyptian government ordered the slaughter of all pigs in Egypt on 29 April.


title: 2009 swine flu pandemic

text: A number of methods have been recommended to help ease symptoms, including adequate liquid intake and rest. Over-the-counter pain medications such as paracetamol and ibuprofen do not kill the virus; however, they may be useful to reduce symptoms. Aspirin and other salicylate products should not be used by people under 16 with any flu-type symptoms because of the risk of developing Reye's Syndrome.


title: 2009 swine flu pandemic

text: If the fever is mild and there are no other complications, fever medication is not recommended. Most people recover without medical attention, although ones with pre-existing or underlying medical conditions are more prone to complications and may benefit from further treatments.


title: 2009 swine flu pandemic

text: People in at-risk groups should be treated with antivirals (oseltamivir or zanamivir) as soon as possible when they first experience flu symptoms. The at-risk groups include pregnant and post partum women, children under two years old, and people with underlying conditions such as respiratory problems. People who are not in an at-risk group who have persistent or rapidly worsening symptoms should also be treated with antivirals. People who have developed pneumonia should be given both antivirals and antibiotics, as in many severe cases of H1N1-caused illness, bacterial infection develops. Antivirals are most useful if given within 48 hours of the start of symptoms and may improve outcomes in hospitalised patients. In those beyond 48 hours who are moderately or severely ill, antivirals may still be beneficial. If oseltamivir (Tamiflu) is unavailable or cannot be used, zanamivir (Relenza) is recommended as a substitute. Peramivir is an experimental antiviral drug approved for hospitalised patients in cases where the other available methods of treatment are ineffective or unavailable.


title: 2009 swine flu pandemic

text: To help avoid shortages of these drugs, the U.S. CDC recommended oseltamivir treatment primarily for people hospitalised with pandemic flu; people at risk of serious flu complications due to underlying medical conditions; and patients at risk of serious flu complications. The CDC warned that the indiscriminate use of antiviral medications to prevent and treat influenza could ease the way for drug-resistant strains to emerge, which would make the fight against the pandemic that much harder. In addition, a British report found that people often failed to complete a full course of the drug or took the medication when not needed.


title: 2009 swine flu pandemic

text: Both medications mentioned above for treatment, oseltamivir and zanamivir, have known side effects, including lightheadedness, chills, nausea, vomiting, loss of appetite, and trouble breathing. Children were reported to be at increased risk of self-injury and confusion after taking oseltamivir. The WHO warned against buying antiviral medications from online sources and estimated that half the drugs sold by online pharmacies without a physical address were counterfeit.


title: 2009 swine flu pandemic

text: In December 2012, the World Health Organization (WHO) reported 314 samples of the 2009 pandemic H1N1 flu tested worldwide have shown resistance to oseltamivir (Tamiflu). It is not totally unexpected as 99.6% of the seasonal H1N1 flu strains tested have developed resistance to oseltamivir. No circulating flu has yet shown any resistance to zanamivir (Relenza), the other available anti-viral.


title: 2009 swine flu pandemic

text: On 8 December 2009, the Cochrane Collaboration, which reviews medical evidence, announced in a review published in "BMJ" that it had reversed its previous findings that the antiviral drugs oseltamivir (Tamiflu) and zanamivir (Relenza) can ward off pneumonia and other serious conditions linked to influenza. They reported that an analysis of 20 studies showed oseltamivir offered mild benefits for healthy adults if taken within 24 hours of onset of symptoms, but found no clear evidence it prevented lower respiratory tract infections or other complications of influenza. Of note, their published finding related only to use in healthy adults with influenza but not in patients judged to be at high risk of complications (pregnant women, children under five and those with underlying medical conditions), and uncertainty over its role in reducing complications in healthy adults still left it as a useful drug for reducing the duration of symptoms. In general, the Cochrane Collaboration concluded "Paucity of good data".


title: 2009 swine flu pandemic

text: While it is not known precisely where or when the virus originated, analyses in scientific journals have suggested that the H1N1 strain responsible for the 2009 outbreak first evolved in September 2008 and circulated amongst humans for several months, before being formally recognised and identified as a novel strain of influenza.


title: 2009 swine flu pandemic

text: The virus was first reported in two U.S. children in March 2009, but health officials have reported that it apparently infected people as early as January 2009 in Mexico. The outbreak was first identified in Mexico City on 18 March 2009; immediately after the outbreak was officially announced, Mexico notified the U.S. and World Health Organization, and within days of the outbreak Mexico City was "effectively shut down". Some countries cancelled flights to Mexico while others halted trade. Calls to close the border to contain the spread were rejected. Mexico already had hundreds of non-lethal cases before the outbreak was officially discovered, and was therefore in the midst of a "silent epidemic". As a result, Mexico was reporting only the most serious cases which showed more severe signs different from those of normal flu, possibly leading to a skewed initial estimate of the case fatality rate.


title: 2009 swine flu pandemic

text: The new strain was first identified by the CDC in two children, neither of whom had been in contact with pigs. The first case, from San Diego County, California, was confirmed from clinical specimens (nasopharyngeal swab) examined by the CDC on 14 April 2009. A second case, from nearby Imperial County, California, was confirmed on 17 April. The patient in the first confirmed case had flu symptoms including fever and cough upon clinical examination on 30 March and the second on 28 March.


title: 2009 swine flu pandemic

text: The first confirmed H1N1/09 pandemic flu death, which occurred at Texas Children's Hospital in Houston, Texas, was of a toddler from Mexico City who was visiting family in Brownsville, Texas, before being air-lifted to Houston for treatment. The Infectious Diseases Society of America estimated that the total number of deaths in the U.S. was 12,469.


title: 2009 swine flu pandemic

text: Influenza surveillance information "answers the questions of where, when, and what influenza viruses are circulating. Sharing of such information is especially crucial during an emergent pandemic as in April 2009, when the genetic sequences of the initial viruses were rapidly and openly shared via the GISAID Initiative within days of identification, playing a key role in facilitating an early response to the evolving pandemic. Surveillance is used to determine if influenza activity is increasing or decreasing, but cannot be used to ascertain how many people have become ill with influenza." For example, as of late June, influenza surveillance information showed the U.S. had nearly 28,000 laboratory-confirmed cases including 3,065 hospitalizations and 127 deaths. But mathematical modelling showed an estimated Americans had the 2009 pandemic flu at the time, according to Lyn Finelli, a flu surveillance official with the CDC. Estimating deaths from influenza is also a complicated process. In 2005, influenza only appeared on the death certificates of 1,812 people in the US. The average annual US death toll from flu is, however, estimated to be 36,000. The CDC explains: "[I]nfluenza is infrequently listed on death certificates of people who die from flu-related complications" and hence, "Only counting deaths where influenza was included on a death certificate would be a gross underestimation of influenza's true impact."

text: Influenza surveillance information on the 2009 H1N1 flu pandemic is available, but almost no studies attempted to estimate the total number of deaths attributable to H1N1 flu. Two studies were carried out by the CDC; the later of them estimated that between 7,070 and 13,930 deaths were attributable to H1N1 flu from April to 14 November 2009. During the same period, 1,642 deaths were officially confirmed as caused by H1N1 flu. The WHO stated in 2010 that total mortality (including unconfirmed or unreported deaths) from H1N1 flu was "unquestionably higher" than their own confirmed death statistics.

text: The initial outbreak received a week of near-constant media attention. Epidemiologists cautioned that the number of cases reported in the early days of an outbreak can be very inaccurate and deceptive, due to several causes, among them selection bias, media bias and incorrect reporting by governments. Inaccuracies could also be caused by authorities in different countries looking at differing population groups. Furthermore, countries with poor health care systems and older laboratory facilities may take longer to identify or report cases. "[E]ven in developed countries the [numbers of flu deaths] are uncertain, because medical authorities don't usually verify who actually died of influenza and who died of a flu-like illness". Joseph S. Bresee, then CDC flu division's epidemiology chief and Michael Osterholm, director of the Center for Infectious Disease Research and Policy pointed out that millions of people have had H1N1 flu, usually in a mild form, so the numbers of laboratory-confirmed cases were actually meaningless, and in July 2009, the WHO stopped keeping count of individual cases and focused more on major outbreaks.

text: A Wisconsin study published in the "Journal of the American Medical Association" in September 2010, reported that findings showed that the 2009 H1N1 flu was no more severe than the seasonal flu. "The risk of most serious complications was not elevated in adults or children", the study's authors wrote. "Children were disproportionately affected by 2009 H1N1 infection, but the perceived severity of symptoms and risk of serious outcomes were not increased." Children infected in the 2009 H1N1 flu pandemic were no more likely to be hospitalized with complications or get pneumonia than those who catch seasonal strains. About 1.5% of children with the H1N1 swine flu strain were hospitalized within 30 days, compared with 3.7% of those sick with a seasonal strain of H1N1 and 3.1% with an H3N2 virus.


title: 2009 swine flu pandemic

text: It has been stated that about 36,000 die from the seasonal flu in the U.S. each year, and this is frequently understood as an indication that the H1N1 strain was not as severe as seasonal influenza. The 36,000 estimate was presented in a 2003 study by CDC scientists and refers to a period from 1990 to 1991 through 1998–99. During those years, the number of estimated deaths ranged from 17,000 to 52,000, with an average of about 36,000. Throughout that decade, influenza A (H3N2) was the predominant virus during most of the seasons, and H3N2 influenza viruses are typically associated with higher death rates. The "JAMA" study also looked at seasonal influenza-associated deaths over a 23-year period, from 1976 to 1977 and 1998–99 with estimates of respiratory and circulatory influenza-associated deaths ranging from about 5,000 to about 52,000, and an average of about 25,000. CDC believes that the range of deaths over the past 31 years (~3,000 to ~49,000) is a more accurate representation of the unpredictability and variability of flu-associated deaths. The annual toll from seasonal influenza in the US between 1979 and 2001 is estimated at 41,400 deaths on average. Therefore, the H1N1 pandemic estimated mortality of 8,870 to 18,300 is just below the mid-range of estimates.


title: 2009 swine flu pandemic

text: The 2009 pandemic caused US hospitals to make significant preparations in terms of hospital surge capacities, especially within the emergency department and among vulnerable populations. In many cases, hospitals were relatively successful in making sure that those patients most severely affected by the influenza strain were able to be seen, treated, and discharged in an efficient manner. A case-study of the preparation, planning, mitigation, and response efforts during the fall of 2009 is that of the Children's Hospital of Philadelphia (CHOP) which took several steps to increase the emergency department (ED) surge capacity response. CHOP used portions of the main lobby area as an ED waiting room; several of the region's hospital-based outpatient facilities were in use during evening and weekend hours for non-emergency cases; the ED's 24-hour short-stay unit was utilized to care for ED patients in a longer-term capacity; non-board certified physicians (in pediatric emergency medicine) and inpatient-unit medical nurses were utilized for ED patient care; hospital units normally utilized for other medical or therapeutic purposes were transformed into ED patient rooms; and rooms normally used for only one patient were expanded to at least a capacity of 2.


title: 2009 swine flu pandemic

text: Annual influenza epidemics are estimated to affect 5–15% of the global population. Although most cases are mild, these epidemics still cause severe illness in people and 290,000–650,000 deaths worldwide every year. On average 41,400 people die of influenza-related illnesses each year in the United States, based on data collected between 1979 and 2001. In industrialised countries, severe illness and deaths occur mainly in the high-risk populations of infants, the elderly and chronically ill patients, although the H1N1 flu outbreak (like the 1918 Spanish flu) differs in its tendency to affect younger, healthier people.


title: 2009 swine flu pandemic

text: In addition to these annual epidemics, Influenza A virus strains caused three global pandemics during the 20th century: the Spanish flu in 1918, Asian flu in 1957, and Hong Kong flu in 1968–69. These virus strains had undergone major genetic changes for which the population did not possess significant immunity. Recent genetic analysis has revealed that three-quarters, or six out of the eight genetic segments, of the 2009 flu pandemic strain arose from the North American swine flu strains circulating since 1998, when a new strain was first identified on a factory farm in North Carolina, and which was the first-ever reported triple-hybrid flu virus.


title: 2009 swine flu pandemic

text: The Spanish flu began with a wave of mild cases in the spring, followed by more deadly waves in the autumn, eventually killing hundreds of thousands in the United States and 50–100 million worldwide. The great majority of deaths in the 1918 flu pandemic were the result of secondary bacterial pneumonia. The influenza virus damaged the lining of the bronchial tubes and lungs of patients, allowing common bacteria from the nose and throat to infect their lungs. Subsequent pandemics have had many fewer fatalities due to the development of antibiotic medicines which can treat pneumonia.


title: 2009 swine flu pandemic

text: The influenza virus has caused several pandemic threats over the past century, including the pseudo-pandemic of 1947 (thought of as mild because although globally distributed, it caused relatively few deaths), the 1976 swine flu outbreak and the 1977 Russian flu, all caused by the H1N1 subtype. The world has been at an increased level of alert since the SARS epidemic in Southeast Asia (caused by the SARS coronavirus). The level of preparedness was further increased and sustained with the advent of the H5N1 bird flu outbreaks because of H5N1's high fatality rate, although the strains currently prevalent have limited human-to-human transmission (anthroponotic) capability, or epidemicity.


title: 2009 swine flu pandemic

text: People who contracted influenza before 1957 appeared to have some immunity to H1N1 flu. According to Daniel Jernigan, head of flu epidemiology for the U.S. CDC "Tests on blood serum from older people showed that they had antibodies that attacked the new virus ... That does not mean that everyone over 52 is immune, since Americans and Mexicans older than that have died of the new flu".


title: 2009 swine flu pandemic

text: In June 2012, a model based study found that the number of deaths related to the H1N1 influenza may have been fifteen times higher than the reported laboratory confirmed deaths, with 80% of the respiratory and cardiovascular deaths in people younger than 65 years and 51% occurring in southeast Asia and Africa. A disproportionate number of pandemic deaths might have occurred in these regions and that efforts to prevent future influenza pandemics need to effectively target these regions.


title: 2009 swine flu pandemic

text: A WHO-supported 2013 study estimated that the 2009 global pandemic respiratory mortality was ~10-fold higher than the World Health Organization's laboratory-confirmed mortality count (18.631). Although the pandemic mortality estimate was similar in magnitude to that of seasonal influenza, a marked shift toward mortality among persons less than 65 years of age occurred, so that many more life-years were lost. Between 123,000 and 203,000 pandemic respiratory deaths were estimated globally for the last nine months of 2009. The majority (62–85%) were attributed to persons under 65 years of age. The burden varied greatly among countries. There was an almost 20-fold higher mortality in some countries in the Americas than in Europe. The model attributed 148,000–249,000 respiratory deaths to influenza in an average pre-pandemic season, with only 19% in persons <65 years of age.

text: The ongoing COVID-19 pandemic is not caused by an influenza virus but SARS-CoV-2, a coronavirus which also primarily affects the respiratory system. As of this pandemic had more than confirmed cases worldwide, and over associated deaths.


title: Chevrolet Corvair

text: The Chevrolet Corvair is a compact car manufactured by Chevrolet for model years 1960–1969 in two generations. A response to the Volkswagen Beetle, it remains the only American-designed, mass-produced passenger car with a rear-mounted, air-cooled engine. The Corvair was manufactured and marketed in 4-door sedan, 2-door coupe, convertible, 4-door station wagon, passenger van, commercial van, and pickup truck body styles in its first generation (1960–1964) and as a 2-door coupe, convertible or 4-door hardtop in its second (1965–1969) – with a total production of approximately 1.8 million from 1960 until 1969.


title: Chevrolet Corvair

text: The name "Corvair" originated as a portmanteau of Corvette and Bel Air, a name first applied in 1954 to a Corvette-based concept with a hardtop fastback-styled roof, part of the Motorama traveling exhibition. When applied to the production models, the "air" part referenced the engine's cooling system.


title: Chevrolet Corvair

text: A prominent aspect of the Corvair's legacy derives from controversy surrounding its handling, brought to light by Ralph Nader's "Unsafe at Any Speed" and tempered by a 1972 Texas A&M University safety commission report for the National Highway Traffic Safety Administration which found that the 1960–1963 Corvair possessed no greater potential for loss of control in extreme situations than its contemporaries.


title: Chevrolet Corvair

text: Chevrolet would more directly compete with imports the size of the Volkswagen Beetle with the subcompact Chevrolet Vega a year after Corvair production ended from 1970 to 1977. Today the Corvair has a devoted following among owners and collectors as average prices for Corvairs from any year have reached an all-time high.


title: Chevrolet Corvair

text: In 1952, Ed Cole was promoted to chief engineer of the Chevrolet Motor Division. Four years later, in July 1956, he was named General Manager of Chevrolet (GM's largest automotive division) and became a vice president of General Motors. At Chevrolet, Cole pushed for many of the major engineering and design advancements introduced in the Chevrolet car and truck lines between 1955 and 1962. He was completely involved in the development and production of the air-cooled rear-engine Corvair. The Corvair was a ground-breaking car in its day. As chief engineer, Cole was also heavily involved in the development of the Corvette sports car. He is also known as the "father" of the small-block Chevy V8, one of the most celebrated engines in American automotive history.


title: Chevrolet Corvair

text: The first time Chevrolet manufactured an air-cooled engine was briefly in 1923 with the Chevrolet Series M Copper-Cooled, which due to engineering challenges, was deemed a failure.


title: Chevrolet Corvair

text: By the late 1950s, the physical size of the entry-level models offered by the Big Three American domestic auto manufacturers (General Motors, Ford, and Chrysler) had grown considerably; effectively abandoning the market for the smaller vehicles that had been available in the past. A successful modern "compact car" market segment was established in the U.S. by the 1950 Nash Rambler. Growing sales of imports from Europe, such as Volkswagen, Renault, Fiat and others, showed that demand existed in the U.S. market for small cars, often as a second car or an alternative for budget-minded consumers. While the "Big Three" continued to introduce ever-larger cars during the 1950s, the new American Motors Corporation (AMC) focused its business strategy on smaller-sized and fuel-efficient automobiles, years before a real need for them existed. AMC, a far smaller company than the "Big Three", positioned itself as a "dinosaur-fighter" (underdog); its compact Rambler models helped push AMC to third place in domestic automobile sales. American Motors also reincarnated its predecessor company's smallest Nash model as the "new" 1958 Rambler American for a second model run, an almost unheard-of phenomenon in automobile history. In 1959, Studebaker followed AMC's formula by restyling its mainstream economy-model sedan, calling it the Lark and billing it as a compact. The Lark success helped give Studebaker a respite for several years before the company ceased automobile production in 1966.


title: Chevrolet Corvair

text: During 1959 and 1960, the Big Three automakers planned to introduce their own "compact" cars. Ford and Chrysler's designs were scaled-down versions of the conventional American car, using six-cylinder engines instead of V8s, and with bodies about 20% smaller than their standard cars.


title: Chevrolet Corvair

text: An exception to this strategy was the Chevrolet Corvair. Chevrolet designed a car that deviated from traditional American norms of design, powered by an air-cooled, horizontally opposed six-cylinder engine with many major components in aluminum. The engine was mounted in the rear of the car, driving the rear wheels through a compact transaxle. The suspension was independent on all four wheels. Bodywork used monocoque rather than body-on-frame construction. The tires were a wider, low-profile design mounted on wider wheels. The styling was unconventional for Detroit, with no tail-fins or chrome grille. Its engineering earned numerous patents. "Time" magazine put Ed Cole and the Corvair on the cover, and "Motor Trend" named the Corvair as the 1960 "Car of the Year".


title: Chevrolet Corvair

text: Corvairs sold more than 200,000 in each of its first six model years. Chevrolet claimed that the rear-engine design offered packaging and economy advantages, providing the car with a lower silhouette, flat passenger compartment floor, no need for power-assisted steering or brakes as well as improvements in ride quality, traction, and braking balance. The design also attracted customers of other makes, primarily imports. The Corvair stood out, with engineering different from other American offerings. It used GM's Z-body, with design and engineering that advanced the rear-engine, rear-wheel-drive layout, which at the time had recently been re-popularized by cars including the Tatra 77, Tucker 48, Fiat 500, Porsche 356, Volkswagen Beetle, Renault Dauphine, Subaru 360, and NSU Prinz, and employed by the concurrent and short-lived Hino Contessa.


title: Chevrolet Corvair

text: In 1962, Subaru built a prototype sedan with an air-cooled flat four engine and installed it in front of the vehicle with front wheel drive. The prototype was not placed into production but the technology was modified and introduced in 1966 as the Subaru 1000 using a water-cooled flat four engine.


title: Chevrolet Corvair

text: The Corvair's engine was an overhead-valve aluminum, air-cooled flat-six (later enlarged, first to 145 and then to 164 cubic inches). The first Corvair engine produced . Power peaked with the 1965–66 turbocharged Corsa engine option. The first generation model's swing axle rear suspension, invented and patented by engineer Edmund Rumpler in 1903, offered a comfortable ride. The design was replaced in 1965 model year with a fully independent trailing arm rear suspension similar to the Corvette Sting Ray.

text: The 1960 Corvair and designers William L. "Bill" Mitchell and styling staff received an Industrial Designers Institute (IDI of NY) award.


title: Chevrolet Corvair

text: The 1960 Corvair Body Styles 569 and 769 four-door sedans were conceived as economy cars offering few amenities to keep the price competitive, with the 500 Series selling for $2,038 ($ in dollars ). Powered by the Chevrolet Turbo-Air 6 engine with and mated to a three-speed manual or optional extra-cost two-speed Powerglide automatic transmission (RPO 360), the Corvair was designed to have comparable acceleration to the six-cylinder full-sized Chevrolet Biscayne. The Corvair's unique design included the "Quadri-Flex" independent suspension and "Unipack Power Team" of engine, transmission, and rear axle combined into a single unit. Similar to designs of European cars such as Porsche, Volkswagen, Mercedes-Benz, and others, "Quadri-Flex" used coil springs at all four wheels with independent rear suspension arms incorporated at the rear. Specially designed 6.5 by 13-inch four-ply tires mounted on 5.5 by 13 inch wheels were standard equipment. Available options included RPO 360, the Powerglide two-speed automatic transmission ($146), RPO 118, a gasoline heater ($74), RPO 119, an AM tube radio ($54), and by February 1960, the rear folding seat (formerly $32) was made standard. Chevrolet produced 47,683 of the 569 model and 139,208 769 model deluxe sedans in 1960.


title: Chevrolet Corvair

text: In January 1960 two-door coupe models were introduced designated as the 527 and 727 body styles. Despite their late January introduction of the coupe, these cars sold well; about 14,628 base model 527 coupes, 36,562 model 727 deluxe coupes. Following the success of the upmarket "Mr. and Mrs. Monza" styling concept cars at the 1960 Chicago Auto Show, management approved the neatly appointed bucket-seat DeLuxe trim of the 900 series Monza as a two-door club coupe only. The new Monza began arriving at Chevrolet dealers in April 1960 with sales of 11,926 Monza club coupes, making the coupe one of the most popular Corvairs.


title: Chevrolet Corvair

text: The success of the Monza model showed Chevrolet management that the compact Corvair was viewed as more of a specialty car than a competitor in the economy segment to the conventionally designed Ford Falcon or Chrysler's Valiant. Chevrolet began a design program that resulted in the 1962 Chevy II, a conventional layout compact.


title: Chevrolet Corvair

text: The option of a more powerful engine for the Corvair was introduced in February 1960. The RPO 649, marketed as "Super Turbo Air", included a hotter camshaft, revised dual-spring cylinder heads, and a lower restriction 2-inch muffler to deliver at 4,800 rpm and of torque at 2,800 rpm. In its first year, it was available on any Corvair model with a manual transmission.


title: Chevrolet Corvair

text: The advertised February introduction of a full synchromesh, four-speed transmission (RPO 651) was postponed until the 1961 model year. This was due to casting problems with the aluminum three-speed transmission case which resulted in technical service bulletins to dealers advising of the potential for differential failure due to external leaks at the front of the transmission's counter gear shaft. The revision of the four-speed transmission designated for 1961 introduction incorporated a cast-iron case and a redesign of the differential pinion shaft to interface with a longer transmission output shaft and a concentric pilot for the revised transmission case. These are among many of the improvements undertaken by Chevrolet by the end of the 1960 model year.


title: Chevrolet Corvair

text: In 1961, Chevrolet introduced the Monza upscale trim to the four-door sedans and the club coupe body styles. With its newly introduced four-speed floor-mounted transmission, DeLuxe vinyl bucket seats, and upscale trim, the Monza Club Coupe gained in sales, as nearly 110,000 were produced along with 33,745 Monza four-door sedans. The four-speed Monza caught the attention of the younger market and was sometimes referred to as "the poor man's Porsche" in various car magazines. The Monza series contributed to about half of the Corvair sales in 1961.


title: Chevrolet Corvair

text: A station wagon, marketed as the Lakewood, joined the lineup in 1961 with its engine located under the cargo floor and offering 68 ft³ (1.9 m³) of cargo room; 58 ft³ in the main passenger compartment, and another 10 ft³ in the front trunk. The Corvair engine received its first size increase to via a slight increase in bore size and was rated at . The base engine was still rated at when paired with the manual transmissions but this increased to when mated to the optional automatic transmission in Monza models. To increase luggage capacity in the front trunk, the spare tire was relocated to the engine compartment (in cars without air conditioning) and new "direct air" heater directed warmed air from the cylinders and heads to the passenger compartment. The gasoline heater remained available as an option through 1963. Factory air conditioning was offered as a mid-1961 option introduction. The condenser lay flat atop the horizontal engine fan. A large, green-painted reverse rotation version of the standard GM Frigidaire air-conditioning compressor was used, and an evaporator housing was added under the dash with integrated outlets surrounding the radio housing. Air conditioning was not available on wagons, Greenbrier/Corvair 95, or the turbocharged models introduced later, due to space constraints. Chevrolet also introduced the Corvair 95 line of light-duty trucks and vans, using the Corvair Powerpack with forward-control, or "cab over", with the driver sitting over the front wheels, as in the Volkswagen Type 2.


title: Chevrolet Corvair

text: The Greenbrier Sportswagon used the same body as the "Corvan 95" panel van with the side windows option, but was marketed as a station wagon and was available with trim and paint options similar to the passenger cars. The "Corvan 95" model was also built in pickup versions; the Loadside was a fairly typical pickup of the era, except for the rear engine, forward controls, and a pit in the middle of the bed. The more popular Rampside had a unique, large, fold-down ramp on the side of the bed for ease of loading wheeled items.


title: Chevrolet Corvair

text: In 1962, Chevrolet introduced the Corvairs with few changes at the beginning of the year. The bottom line 500 series station wagon was dropped and the 700 became the base station wagon. The "Lakewood" name was dropped. The ever-popular Monza line then took on a wagon model to round out the top of the line. In spring of 1962, Chevrolet committed itself to the sporty image they had created for the Corvair by introducing a convertible version, then offering a high-performance turbocharged "Spyder" option for Monza coupes and convertibles, making the Corvair the second production automobile supplied with a turbocharger as a factory option, with the Oldsmobile F-85 Turbo Jetfire having been released earlier in 1962. Corvair station wagons were discontinued at that point in favor the new Corvair Convertible and Chevy II (built at the same assembly plant). The slow-selling Loadside pickup was discontinued at the end of the model year. The rest of the Corvair 95 line of Forward Control vehicles continued. Optional equipment on all passenger cars (except wagons) included metallic brake linings and a heavy-duty suspension consisting of a front anti-roll bar, rear-axle limit straps, revised spring rates, and recalibrated shock absorbers. These provided a major handling improvement by reducing the potentially violent camber change of the rear wheels when making sharp turns at high speeds. The Turbocharged Spyder equipment group featured a multi-gauge instrument cluster which included a tachometer, cylinder head temperature, and intake manifold pressure gauges, Spyder fender script, and Turbo logo deck emblems, in addition to the high-performance engine.


title: Chevrolet Corvair

text: The Monza Coupe was the most popular model with 151,738 produced out of 292,531 total Corvair passenger car production for 1962. John Fitch, chose the Corvair as the basis for "Sprint" models. These included various performance improvements along with appearance modifications. Individual components were available to customers and several Chevrolet dealers became authorized to install the "Sprint" conversions.


title: Chevrolet Corvair

text: The 1963 model year had the optional availability of a long 3.08 gear for improved fuel economy, but the Corvair otherwise remained largely carryover with minor trim and engineering changes. Self-adjusting brakes were new for 1963. Of all the Corvairs sold in 1963, fully 80% were Monzas. The convertible model accounted for over 20% of all the Monzas sold.


title: Chevrolet Corvair

text: Significant engineering changes were introduced for 1964, while the model lineup and styling remained relatively unchanged. The engine displacement was increased from by an increase in stroke. The base engine power increased from , and the high-performance engine increased from . The Spyder engine rating remained at despite the displacement increase of the engine. In 1964, an improvement in the car's swing axle rear suspension occurred with the addition of a transverse leaf spring along with softer rear coil springs designed to diminish rear roll stiffness and foster more neutral handling. Spring rates could now be softer at both ends of the car compared to previous models. The heavy-duty suspension was no longer optional, although all models now had a front anti-roll bar as standard. Brakes were improved with finned rear drums. The remaining pickup, the Rampside, was discontinued at the end of the model year.


title: Chevrolet Corvair

text: Despite a vastly improved 1964 model, Corvair sales declined by close to 73,000 units that year. This was attributed to a number of factors, including the basic styling being 5 years old, the lack of a pillarless hardtop (which virtually all competing compact models had), the lack of a V8 engine, and the introduction of the Ford Mustang on 17 April, which broke all records for sales of a new car (and cut into Corvair sales).


title: Chevrolet Corvair

text: The Corvair second generation arrived for model year 1965, noted for its lack of a "B" pillar and a new fully independent suspension replacing the original swing axle rear suspension. The Corvair used coil springs at each wheel.


title: Chevrolet Corvair

text: "Car and Driver" magazine's David E. Davis Jr. showed enthusiasm for the 1965 Corvair in their October 1964 issue:


title: Chevrolet Corvair

text: The standard and optional engines were carried forward from 1964. The previous Spyder engine was replaced by the normally aspirated for the new Corsa. The engine was unusual in offering four single-throat carburetors, to which were added larger valves and a dual exhaust system. A turbocharged engine was optional on the Corsa, which offered either standard three-speed or optional (US$92) four-speed manual transmissions. The engine was optional on 500 and Monza models with manual or Powerglide transmissions. All engines got some of the heavy-duty internal parts from the Turbocharged engine for better durability.


title: Chevrolet Corvair

text: New refinements appeared on the 1965 redesign. The Corsa came standard with an instrument panel featuring a speedometer with resettable trip odometer, a 6,000 rpm tachometer, cylinder head temperature gauge, analog clock with a sweeping second hand, a manifold vacuum/pressure gauge and fuel gauge. A much better heater system, larger brakes borrowed from the Chevelle, a stronger differential ring gear, an alternator (replacing the generator), and significant chassis refinements were made. A new fully articulated rear suspension virtually eliminated the danger of the previous generation's swing axles and was based on the contemporary Corvette Sting Ray (Corvair used coil springs while the Sting Ray uses a transverse leaf). Additionally, an AM/FM stereo radio, in-dash All Weather Air Conditioning, telescopically adjustable steering column, and a Special Purpose Chassis Equipment ("Z17") handling package, consisting of a special performance suspension and quick ratio steering box, were new options for 1965. The Monza and Corvair 500 Sport Sedans were the only compact cars ever available in the U.S. as pillarless four-door hardtops.


title: Chevrolet Corvair

text: The station wagon, panel van, and pickup body styles had all been dropped and 1965 was the last year for the Greenbrier window van, which was retained mainly for fleet orders, with 1,528 being built. In all, 235,528 Corvairs were built in 1965, an increase of 30,000 units over 1964. Chevrolet replaced the Corvair-based vans with the Chevrolet Sportvan/GMC Handi-Van, which used a traditional front-engine/rear-drive axle borrowed from the Chevy II.
