Prevention of<unk>  has three components: prevention in pigs, prevention of transmission to humans, and prevention of its spread among humans. Proper handwashing techniques can prevent the virus from spreading. Avoid touching the eyes, nose, or mouth. Stay away from others who display symptoms of the cold or flu and avoid contact with others when displaying symptoms.<unk>  Methods of preventing the spread of<unk>  among<unk>  include facility management, herd management, and vaccination (ATCvet code: ). Because much of the illness and death associated with<unk>  flu involves secondary infection by other pathogens, control strategies that rely on vaccination may be insufficient. Control of<unk>  by vaccination has become more difficult in recent decades, as the evolution of the virus has resulted in inconsistent responses to traditional vaccines. Standard commercial<unk>  flu vaccines are effective in controlling the infection when the virus strains match enough to have significant cross-protection, and custom (autogenous) vaccines made from the specific viruses isolated are created and used in the more difficult cases. Present vaccination strategies for SIV control and prevention in<unk>  farms typically include the use of one of several bivalent SIV vaccines commercially available in the United States. Of the 97 recent H3N2 isolates examined, only 41 isolates had strong serologic cross-reactions with antiserum to three commercial SIV vaccines. Since the protective ability of<unk>  vaccines depends primarily on the closeness of the match between the vaccine virus and the epidemic virus, the presence of nonreactive H3N2 SIV variants suggests current commercial vaccines might not effectively protect pigs from infection with a majority of H3N2 viruses. The United States Department of Agriculture researchers say while pig vaccination keeps pigs from getting sick, it does not block infection or shedding of the virus. Facility management includes using disinfectants and ambient temperature to control viruses in the environment. They are unlikely to survive outside living cells for more than two weeks, except in cold (but above freezing) conditions, and are readily inactivated by disinfectants. Herd management includes not adding pigs carrying<unk>  to herds that have not been exposed to the virus. The virus survives in healthy carrier pigs for up to three months and can be recovered from them between outbreaks. Carrier pigs are usually responsible for the introduction of SIV into previously uninfected herds and countries, so new animals should be quarantined. After an outbreak, as immunity in exposed pigs wanes, new outbreaks of the same strain can occur. Humans ;Prevention of pig-to-human transmission thumb<unk>  can be infected by both avian and human flu strains of<unk> , and therefore are hosts where the antigenic shifts can occur that create new<unk>  strains. The transmission from<unk>  to humans is believed to occur mainly in<unk>  farms, where farmers are in close contact with live pigs. Although strains of<unk>  are usually not able to infect humans, it may occasionally happen, so farmers and veterinarians are encouraged to use face masks when dealing with infected animals. The use of vaccines on<unk>  to prevent their infection is a major method of limiting<unk> -to-human transmission. Risk factors that may contribute to the<unk> -to-human transmission include smoking and, especially, not wearing gloves when working with sick animals, thereby increasing the likelihood of subsequent hand-to-eye, hand-to-nose, or hand-to-mouth transmission. ; Prevention of human-to-human transmission<unk>  spreads between humans when infected people cough or sneeze, then other people breathe in the virus or touch something with the virus on it and then touch their own face. "Avoid touching your eyes, nose or mouth. Germs spread this way."<unk>  flu cannot be spread by pork products, since the virus is not transmitted through food. The<unk>  flu in humans is most contagious during the first five days of the illness, although some people, most commonly children, can remain contagious for up to ten days. Diagnosis can be made by sending a specimen, collected during the first five days, for analysis. Thermal imaging camera and screen, photographed in an airport terminal in Greece – thermal imaging can detect elevated body temperature, one of the signs of the virus H1N1<unk> . Recommendations to prevent the spread of the virus among humans include using standard infection control, which includes frequent washing of hands with soap and water or with alcohol-based hand sanitizers, especially after being out in public. Chance of transmission is also reduced by disinfecting household surfaces, which can be done effectively with a diluted chlorine bleach solution. Experts agree hand-washing can help prevent viral infections, including ordinary and<unk>  flu infections. Also, avoiding touching one's eyes, nose, or mouth with one's hands helps to prevent the flu.<unk>  can spread in coughs or sneezes, but an increasing body of evidence shows small droplets containing the virus can linger on tabletops, telephones, and other surfaces and be transferred via the fingers to the eyes, nose, or mouth. Alcohol-based gel or foam hand sanitizers work well to destroy viruses and bacteria. Anyone with flu-like symptoms, such as a sudden fever, cough, or muscle aches, should stay away from work or public transportation and should contact a doctor for advice. Social distancing, another tactic, is staying away from other people who might be infected, and can include avoiding large gatherings, spreading out a little at work, or perhaps staying home and lying low if an infection is spreading in a community. Public health and other responsible authorities have action plans which may request or require social distancing actions, depending on the severity of the outbreak. Vaccination Vaccines are available for different kinds of<unk>  flu. The U.S. Food and Drug Administration (FDA) approved the new<unk>  flu vaccine for use in the United States on September 15, 2009. Studies by the National Institutes of Health show a single dose creates enough antibodies to protect against the virus within about 10 days. In the aftermath of the 2009 pandemic, several studies were conducted to see who received<unk>  vaccines. These studies show that whites are much more likely to be vaccinated for seasonal<unk>  and for the H1N1 strain than African Americans This could be due to several factors. Historically, there has been mistrust of vaccines and of the medical community from African Americans. Many African Americans do not believe vaccines or doctors to be effective. This mistrust stems from the exploitation of the African American communities during studies like the Tuskegee study. Additionally, vaccines are typically administered in clinics, hospitals, or doctor's offices. Many people of lower socioeconomic status are less likely to receive vaccinations because they do not have health insurance. Surveillance Although there is no formal national surveillance system in the United States to determine what viruses are circulating in pigs, an informal surveillance network in the United States is part of a world surveillance network.
