Avian influenza is an infection caused by avian (bird) influenza (flu)
viruses. These influenza viruses occur naturally among birds. Wild
birds worldwide carry the viruses in their intestines, but usually do
not get sick from them. However, avian influenza is very contagious
among birds and can make some domesticated birds, including chickens,
ducks, and turkeys, very sick and kill them. For a summary of Avian Flu facts, click on the PDF link below.
