The Wayne County case involves a backyard poultry flock, the press release said. That case was confirmed after an investigation by the Michigan Department of Agriculture and Rural Development and the Michigan State University Veterinary Diagnostic Library.

For the first time, birds in a Wayne County backyard flock have been sickened by the highly pathogenic H5N1 avian influenza virus, MDARD reported.

Georgia has confirmed the first positive case of the highly pathogenic avian influenza, also known as bird flu, in a commercial poultry operation, according to Georgia Agriculture Commissioner Tyler Harper.
