August 19, 2011
OLYMPIA–A mosquito sample collected in Yakima County on Tuesday tested positive for West Nile virus providing the first sign that the virus is present in Washington this year. Monitoring and testing dead birds and mosquitoes has been ongoing around the state since June.
In 2009, 38 people in Washington became sick from West Nile virus infections. Last year we had two human cases in the state. Although there have been no human cases identified this year, people should be aware that the virus is here and can cause very serious illness.
