Avian Influenza Disease

USDA’s  Animal and Plant Health Inspection Service (APHIS) works to keep avian influenza (AI), a serious poultry disease, from becoming established in the U.S. poultry population.  AI viruses can infect chickens, turkeys, pheasants, quail, ducks, geese and guinea fowl, as well as a wide variety of other birds.  Avian influenza findings can negatively impact poultry trade, so APHIS and its partners work together to protect the vitality of this important segment of the country’s livestock industry.

Since December 2014, APHIS has confirmed more than 200 cases of highly pathogenic avian influenza (HPAI) H5 in U.S commercial and backyard poultry flocks, as well as in wild birds.  APHIS is working with state and industry partners to address this outbreak.  The Centers for Disease Control and Prevention (CDC) considers the risk to the general public from these HPAI H5 infections to be low, with no human cases of these specific viruses detected in the world.
