Bird flu case confirmed in Dane County

Bird flu has been infecting wild birds around the world for decades, but the latest US outbreak started in January 2022 and has featured more spread among mammals than in past years.
MADISON, Wis. — A case of highly pathogenic avian influenza, also known as bird flu, was identified in a backyard poultry flock in Dane County, the Wisconsin Department of Agriculture, Trade and Consumer Protection announced on Monday.
The U.S. Department of Agriculture animal health officials and DATCP have been working together in a joint incident response. The affected premises has been quarantined to restrict movement of poultry and poultry products.
H5N1 HPAI viruses are highly contagious and often fatal to domestic poultry. Caused by influenza type A viruses, the disease varies in severity depending on the strain and species affected. Bird flu can be spread by contact with infected birds, commingling with wild birds or their droppings, equipment, or clothing worn by anyone working with the animals.
Officials confirmed that the birds on the property were depopulated to prevent the spread of the disease, preventing them from entering the food system.
DATCP encourages poultry owners to implement strong biosecurity measures to protect their animals from the disease. Poultry owners are asked, when possible, to keep their birds indoors.
Poultry owners are encouraged to continue monitoring their herd and flock health. To report signs of illness, follow the instructions on the DATCP Animal Disease Reporting website or contact DATCP at (608) 224-4872 (business hours) or (800) 943-0003 (after hours and weekends).
The HPAI H5N1 virus has continued to circulate in both wild and domestic birds in North America since December 2021. Since that time, the H5N1 virus has also affected other species, including mammals.
