West Nile virus infection has been confirmed in several birds in Washington and Multnomah counties. There have been no confirmed infections in humans in western Oregon. Human illness from West Nile virus is rare, even in areas where the virus has been reported. The chance that any one person is going to become ill from a mosquito bite is low. However, concern for one's personal health has many asking questions about how best to prepare and protect themselves from West Nile virus.
In response to public concern Tigard's staff has initiated the Mosquito Sampling & Monitoring Program in which staff members inspect storm water ponds, local wetlands and streams, and the public drainage system for mosquito larva. In addition, Tigard has contracted with Washington County Mosquito Control to perform larvicide mosquito control at city owned wetlands; and maintains relationships with the Department of Health and Human Services, Washington County and other local cities to track possible cases of West Nile virus. Please note, the city does NOT perform mosquito control on private properties.
