    Avian Influenza Detected in Three Skunks in Stevens County

    Northeast Tri County Health District and the Washington Department of Fish and Wildlife (WDFW) ask the public to avoid contact with birds and other wild animals, especially sick or dead wild animals or their young, to prevent the spread of avian influenza, also known as bird flu. In February 2024, three skunks located in Stevens County tested positive for the highly pathogenic avian influenza (HPAI) H5N1 strain.

    Since May 2022, an outbreak of avian influenza has been impacting wild birds across Washington, the northwest, and globally. Avian influenza has been detected in cases of wild mammals in our state. These positive cases of HPAI in wild mammals include a bobcat in northeast Washington, several seals in Puget Sound, and three raccoons in various locations across the state.​..
