West Nile Virus
What was expected has arrived...

West Nile virus West Nile virus, which has been steadily spreading across the United States, has reached Washington. A raven from Pend Oreille County and a crow from Snohomish County collected as part of a statewide dead bird surveillance effort tested positive for the virus. The disease has also been confirmed in two horses, one from Island County and the other from Whatcom County. These are the first detections of West Nile virus in our state. Currently, we have received no reports of human cases. Transmitted by mosquito bites to humans, the virus has proven itself a public health threat. As of March 12, 4,161 cases of the illness have been reported to the Centers for Disease Control and Prevention for the past season, including 277 fatalities. The Washington State Department of Health coordinates surveillance throughout the state for the virus and mosquitoes that potentially carry the virus. However, all of Washington residents can help prevent outbreaks. Below are tools, resources, and information for the general public, health care providers, veterinarians, local health departments, and mosquito control districts.
