Bird Flu Spreads to Washington Wildlife: Cougars and Raccoons Infected
Bird flu is spreading rapidly, moving beyond domestic poultry to infect a growing number of wild animals in Washington state. Experts from the Washington Department of Fish and Wildlife (WDFW) have confirmed infected cases in cougars, raccoons, and a range of wild birds. This raises concerns about the potential for the virus to continue to evolve and spread.
What is Highly Pathogenic Avian Influenza (HPAI)?
Highly pathogenic avian influenza (HPAI) is a dangerous strain of bird flu that can cause severe illness and death in birds.
According to the United States Geological Survey, "highly pathogenic" identifies viruses with a higher potential to cause severe disease than "low pathogenic" strains. The H5N1 subtype is the predominant strain detected in recent outbreaks.
Widespread Wildlife Infections
Since 2023, WDFW has identified bird flu in various wild animals, including:
- Striped skunks
- Bobcats
- Harbor seals
- Raccoons
- Bald eagles
- Cackling geese
- Crows
- Great horned owls
- Green-winged teal
- Red-tailed hawks
- Snow geese
- Snowy plovers
- Trumpeter swans
Recent cases have included two cougars in Clallam County and a raccoon from Walla Walla, adding to the worrying trend.
Risk to Humans
While the risk of HPAI H5N1 infection in humans is considered low, the CDC emphasizes that the virus can continue to evolve.
They urge continued vigilance and encourage individuals to practice good hygiene and avoid contact with sick animals.
Staying Informed
For updates on HPAI detections in wild mammals, visit the U.S. Department of Agriculture’s website. The World Health Organization (WHO) provides comprehensive information and guidance regarding avian influenza.
It is crucial to monitor developments, stay informed, and practice preventive measures to safeguard both wildlife populations and human health. Remember to report any sightings of sick or deceased wildlife to your local wildlife agency.
