Avian Influenza Cases Confirmed in Multiple States

The highly pathogenic avian influenza (HPAI) has been detected in multiple locations across the U.S., including a backyard flock in Oakland County, Michigan, marking the second case since 2022. The Michigan Department of Agriculture and Rural Development has quarantined the affected property and plans to euthanize the infected birds to prevent further spread. In California, two mute swans tested positive for the virus at Mather Regional Park, while Texas confirmed HPAI in wild birds found in Austin. A human case of H5N1 was reported in Stanislaus County, California, linked to contact with infected dairy cattle, bringing the total number of human cases in the U.S. to 66. Health officials emphasize that the public health risk remains low, advising people to avoid contact with sick or dead animals and to adhere to biosecurity measures. The CDC continues to monitor the situation as outbreaks persist in both poultry and dairy herds nationwide.
