The Wisconsin Department of Health Services (DHS) has identified the first presumptive positive human case of Highly Pathogenic Avian Influenza A (H5N1), commonly referred to as bird flu, in Barron County. This follows the detection of an infected flock of commercial poultry in the same area. The individual had exposure to this flock and was tested at the Wisconsin State Lab of Hygiene. Confirmation is pending from the Centers for Disease Control and Prevention (CDC).

DHS, alongside Barron County Health and Human Services, is monitoring farm workers who might have been exposed to the virus. They are also providing these individuals with health protection information. Despite this case, DHS assures that "the risk to the general public in Wisconsin remains low." Individuals working closely with infected animals or having recreational contact with them face a higher risk.

The H5N1 virus has been present in both wild and domestic birds across North America since December 2021. Known for being highly contagious and often fatal to domestic poultry, it can lead to varying levels of illness depending on the strain and species affected. Transmission occurs through direct contact with infected birds or their droppings, or via contaminated equipment or clothing.

Human infection is rare but typically involves direct contact with infected animals. Symptoms in humans include flu-like symptoms or eye infections. In such cases, individuals are advised to stay home and consult healthcare providers before visiting medical facilities.

Consuming fully cooked eggs, poultry, meat, pasteurized milk products like cheese and yogurt remains safe. General precautions should be observed when handling raw meat or eggs to prevent germ spread.

Further updates will be available on Outbreaks, Recalls, and Investigations in Wisconsin. Prevention guidelines for those working closely with birds or other relevant animals can be found under Protective Actions for People.
