Bird Flu

Avian Influenza:

Avian influenza is an infectious disease of birds caused by type A strains of the influenza virus. These flu viruses occur naturally among birds. All birds are thought to be susceptible to infection with avian influenza, though some species are more resistant to infection than others. The disease, which was first identified in Italy more than 100 years ago, occurs worldwide.

Avian influenza viruses do not normally infect species other than birds and pigs. Although avian influenza A viruses usually do not infect humans, more than 100 confirmed cases of human infection with avian influenza viruses have been reported since 1997. Most cases of avian influenza infection in humans are thought to have resulted from direct contact with infected poultry or contaminated surfaces. To date, there have been no cases of avian influenza A (H5N1) in the United States.

  • 1918 influenza pandemic caused at least 500,000 U.S. deaths and up to 40 million deaths worldwide
