USDA: Detections of Highly Pathogenic Avian Influenza in Wild Birds

Captive wild birds, defined by the World Organisation for Animal Health (WOAH) as a wild animal that is captive or otherwise lives under or requires human supervision or control, are included in the numbers reported on this page. Captive wild birds, including sick wild birds that may have died after being found and taken to a rehabilitator or sanctuary, will have the designation of “captive wild bird” in the WOAH Classification column. To remain consistent with current reporting, information will continue to be broken down to the county level. To protect privacy, private or business names will not be released. This is consistent with current reporting of wild birds as well as commercial and backyard flocks.

APHIS is continuing to process samples collected over the past year from State and partner agencies and will continue to post this information on this page. The detection date is the date of National Veterinary Services Laboratories confirmatory testing. APHIS will provide updates below when there are significant differences between sample collection and detection dates.
