What is H5N1?

What is H5N1? H5N1 (called “Highly Pathogenic Avian Influenza” or “bird flu”) is a disease caused by influenza A viruses. Wild birds, particularly waterfowl, can carry and spread these viruses but may show no signs of illness. However, H5N1 can cause severe disease and death in domestic poultry (such as chickens, turkeys, ducks, and geese). H5N1 is causing illness in dairy cattle in multiple states as well, and cases of H5N1 have also been reported in wild birds, mammals, and other domestic companion animals, such as cats. People with close or prolonged contact with infected animals or contaminated environments may be at a higher risk of avian influenza infection.
