A wild bird in Yolo County has tested positive for highly pathogenic avian influenza (HPAI), the county reported Tuesday.
HPAI is a viral disease that occurs naturally among wild aquatic birds such as ducks, geese, swans, gulls and terns, and shorebirds such as storks, plovers and sandpipers. HPAI can infect domestic poultry, other birds, animal species and humans.
As of Aug. 22, HPAI has been detected in commercial and domestic bird flocks in Sacramento, Butte, Contra Costa and Fresno counties.
Additionally, HPAI has been detected in wild birds in the following 12 counties: Butte, Colusa, Glenn, Mendocino, Placer, Plumas, Sacramento, Santa Clara, Siskiyou, Solano, Sonoma and Stanislaus, in addition to Yolo County.
According to a press release from the county, keepers of commercial and domestic flocks are advised to protect their birds by following these and other biosecurity guidelines:
- Prevent contact between domestic and wild birds by bringing your birds into an enclosure that is covered.
- Avoid attracting wild birds and keep your domestic birds away from potentially-contaminated water.
- Use sanitized well or city water an wash hands before and after handling birds.
- Prevent rodents, predators and pets from coming in contact with wild birds.
- Keep feed covered and spills cleaned up to avoid attracting wild birds and rodents.
- Wash and disinfect boots and equipment when moving between coops.
- Clean and disinfect equipment and other supplies between uses and do not share.
- Clean and disinfect your shoes and vehicle tires after visiting feedstores and other places frequented by other poultry owners or wild bird hunters.
- Avoid visiting places where wild birds congregate, such as lakes and ponds.
HPAI can also infect humans. The risk to the general public in Yolo County is very low at this time, the county advised, but residents are reminded to avoid direct contact with wild birds, particularly birds that appear ill or are dead.
