General Information


On April 29th, 2009, the World Health Organization announced that it would no longer refer to the H1N1 Influenza A virus as 'swine flu' to avoid giving a false understanding of the danger posed by pigs.

Viruses regularly cause outbreaks of influenza among pigs. These viruses do not normally infect humans; however, since March 2009, a number of confirmed human cases of a new strain of swine-origin H1N1 Influenza A virus infection in the U.S. and internationally have been identified. Although to date the infection appears to be similar to seasonal flu in severity, the rapid global spread of the virus prompted the World Health Organization to declare a pandemic in June.
