CDC: Three human cases of H5 Bird Flu
Three additional human cases of highly pathogenic avian influenza (HPAI) A(H5) (“H5 bird flu”) virus infection have been confirmed by the Centers for Disease Control and Prevention (CDC) in association with a second poultry farm in Northeast Colorado/Weld County. The three confirmed cases occurred in people who were working directly with infected poultry at a commercial egg layer operation that had reported an outbreak of H5 bird flu among poultry. All three people have mild illness. Confirmation of these three additional cases brings the total number of human cases of H5 bird flu reported in the United States since April 2024 to 13. Four of these cases were associated with exposure to sick dairy cows and nine were associated with exposure to avian influenza A(H5N1)-infected poultry.
