Avian Influenza Questions

Avian flu viruses occur naturally among wild birds, and usually do not affect them. Unlike most avian influenza viruses, the strain of H5N1 currently circulating among birds has caused death in more than 80 species of wild birds. Avian influenza can be very contagious among domestic poultry, including chickens, ducks, and turkeys, making them very sick and often killing them.
