With the mosquito season underway and West Nile virus (WNV) once again a concern, King County residents are asked to contact Public Health with reports of dead birds. Crows in particular die quickly from West Nile virus and clusters of dead crows may indicate that West Nile virus is present in the community. Residents may call (206) 205-4394 or use the on-line reporting form at: www.metrokc.gov/health/westnile/deadbird.htm.

West Nile virus was not found in King County in 2007, though in past years birds and horses have died here from the virus, which is spread through the bite of an infected mosquito. The infection can be asymptomatic, but it can also cause symptoms ranging from mild to severe, including diseases of the brain and spinal column. In the United States in 2007, 3,630 cases of human WNV disease were reported from 44 states, and 124 people died. People of all ages can get WNV disease, but people over 50 are more likely to become seriously ill.
