The designation of pathogenicity is related to severity of illness in poultry not people.) (There have been four human infections with low pathogenic avian influenza A viruses identified in the United States since 2002. No human infections with highly pathogenic avian influenza A viruses have been detected to date in the United States. Human infections with HPAI A(H5) bird flu viruses are rare but can occur, usually after close contact with infected birds. Wild birds can carry HPAI A(H5) viruses without showing symptoms, but these viruses can cause illness and death in domestic poultry. The proper handling and cooking of poultry and eggs to an internal temperature of 165˚F kills bacteria and viruses, including HPAI A(H5) viruses. As a reminder, it is safe to eat properly handled and cooked poultry in the United States. There is existing federal guidance around bird flu exposures for different groups of people, including hunters, poultry producers and the general public, as well as health care providers. However, outbreaks in domestic poultry, in addition to infections in wild birds, may result in increased exposures in some groups of people, particularly poultry workers, for example. The detection of these viruses in poultry does not change the risk to the general public’s health, which CDC considers to be low. ![]() This follows detections of HPAI A(H5) viruses in wild birds in the United States in the preceding weeks. ![]() Department of Agriculture’s (USDA) Animal and Plant Health Inspective Service (APHIS) has announced multiple detections of highly pathogenic avian influenza (HPAI) viruses in U.S.
