The Environmental Health Division often gets questions about animal pests and diseases spread by them. The Washington State Department of Health and the U.S. Centers of Disease Control (CDC) are good sources of information about these diseases.
West Nile virus has been found in animals in western Washington. Clallam County Environmental Health participates in the Washington Department of Health´s testing program to monitor the spread of the virus. Please read our West Nile page for more information.
Rabies is a life threatening viral infection which can spread by contact with the saliva and urine of infected animals. While all mammals can potentially be infected with the rabies virus, only bats are a significant carrier of this infection in Washington State. Rabies is extremely rare in domestic dogs and cats in Washington State.
If someone has been exposed to a bat or bitten by an animal that may be rabid, please read our rabies page and contact the Environmental Health Division at (360) 417-2258 to begin the testing process.
