Swine Influenza (swine flu) is a respiratory disease of pigs caused by type A influenza viruses that regularly cause outbreaks of influenza in pigs. Swine flu viruses do not normally infect humans. However, sporadic human infections with swine flu have occurred. When this happens, these viruses are called "variant viruses." The links below provide guidance related to preventing the spread of influenza A viruses in specific settings.
Note: Guidance related specifically to an H3N2 variant virus is available at Information on H3N2 Influenza A Viruses.
