Avian Influenza (AI)

Avian Influenza (AI) is an infection caused by bird flu viruses, which naturally occur among birds. Wild birds worldwide carry the viruses in their intestines, but usually do not get sick from them. However, AI is very contagious among birds and can make some domesticated birds, including chickens, ducks, and turkeys, very sick and kill them. The strain that is currently being reported in Asia and Europe is AI H5N1.
