This is the same data APHIS has previously made available about HPAI in the United States, but in a new format that is more visual and easier to navigate.

The new page displays high-level information about the outbreak including the number of confirmed flocks, affected states, and total birds affected. Visitors to the page may view a map of birds affected by state and can change the map to view total flocks affected by state, or commercial or backyard flocks by state. A new feature in the data table on the page allows users to see when control areas and surveillance zones have been released for affected counties.

APHIS will continue to announce the first case of HPAI in commercial and backyard flocks detected in a State but will not announce subsequent detections in the State. All cases in commercial and backyard flocks will be listed on this new page, which will be updated by noon Eastern each weekday.

APHIS continues to urge all bird owners to practice good biosecurity, prevent contact between their birds and wild birds, and report sick birds or unusual bird deaths to State/Federal officials, either through their state veterinarian or through APHIS’ toll-free number at 1-866-536-7593. APHIS urges producers to consider bringing birds indoors when possible to further prevent exposures. Additional information on biosecurity for backyard flocks can be found at
