(Wisconsin) Over the past 30 days, the U.S. Department of Agriculture National Veterinary Services Laboratories has confirmed the presence of Highly Pathogenic Avian Influenza or H5N1 in 22 dairy herds in five states including Michigan and South Dakota.
To date there have not been any Aviation Influenza detections in Wisconsin cattle, poultry, or wildlife with the genotype associated with dairy cattle detections in other states. Four human cases have been reported in the United States following exposure to dairy in cattle.
The Wisconsin Department of Health Services continues to encourage those who work with animals or materials that could be potentially infected with novel influenza A viruses to take appropriate precautions and wear personal protection equipment according to CDC guidance.
