Public Health – Seattle & King County (Public Health) is the lead agency for West Nile virus (WNV) response in King County. Public Health conducts surveillance for WNV in people, animals, and mosquitoes; provides educational materials and resources; conducts outreach and public education; coordinates mosquito control activities throughout the county; and provides cities and partner agencies with training and technical assistance. Adult mosquito control activities (e.g., spraying) would also be coordinated through Public Health if deemed necessary in the event of a human outbreak.

Public Health works closely with King County agencies and local jurisdictions to provide technical assistance and educational materials to meet the needs of their communities. Public Health coordinates an interagency work group (IAWG) for cities and agencies. This group meets periodically during the WNV season. For more information on the IAWG and agency coordination contact the Public Health Environmental Health Services office at 206-205-4394.
