WHAT TO KNOW
A(H5) Bird Flu Human Cases in U.S.
On July 7, 2025, CDC streamlined A(H5) bird flu updates with routine influenza data updates and updated reporting cadences to reflect the current public health situation. As such, the following changes were made to this page: Data on the number of people monitored and tested for bird flu are available at A(H5) Bird Flu Surveillance and Human Monitoring | Bird Flu | CDC and are reported monthly. USDA data on highly pathogenic avian influenza (HPAI) detections in animals will no longer be reported on the CDC website. These data can be found on USDA's website. CDC will continue to report any additional human cases of A(H5) bird flu here and in FluView.
