Highly Pathogenic Avian Influenza

Highly pathogenic avian influenza (HPAI) H5 infections have been reported in U.S. domestic poultry (backyard and commercial flocks), captive wild birds, and wild birds by the U.S. Department of Agriculture (USDA) and the U.S. Department of Interior (DOI). HPAI H5 detections began in December 2014 and continued into mid-June 2015. During that time H5 bird flu virus detections were reported in 21 U.S. states (15 states with outbreaks in domestic poultry or captive birds and 6 states with H5 detections in wild birds only). It is possible that H5 outbreaks in birds in the United States may recur in the fall and winter. Surveillance for H5 in U.S. birds is ongoing. There have been no human infections in the U.S. associated with H5 AI viruses.
