Avian influenza updates

Highly pathogenic avian influenza (HPAI) cases are now confirmed in domestic birds, wild birds, and wild mammals throughout most of North America. HPAI, subtype H5N1 was first detected in Michigan in late February 2022 Since then, Michigan has detected HPAI H5N1 in wild birds and mammals across the state. Monitoring of sick and dead wildlife for HPAI continues and the disease is considered widespread and endemic across Michigan and North America. The Michigan Department of Agriculture and Rural Development continues to take swift action in response to this disease and is closely monitoring and responding to reports of sick domestic birds and HPAI throughout the state. . The strain now present in North America has caused extensive illness and death in a range of wild bird species. In particular, waterfowl, raptors, scavengers, gulls and terns have been affected. The DNR is focusing its surveillance efforts by prioritizing testing dead birds from die-offs of six or more birds, as well as bald eagles, and abnormal acting hawks, owls, and wild mammals.
