El Dorado's first human West Nile case diagnosed

EL DORADO COUNTY - The county's first human case of West Nile virus has been confirmed, county public health and environmental management officials announced Monday.

They reported that a female under the age of 50 was diagnosed with the virus last week and is recovering from the illness. Greg Stanton, county environmental health manager, said the case occurred in the western part of the county, but he declined to be more specific.

Stanton said the county began trapping mosquitoes last month after confirming its first case of West Nile virus in a horse. Results of tests on the mosquitoes are expected any day, he said.

Depending on the results, Stanton said, truck-mounted spraying could be considered for areas most at risk. Since June, three staff members have been going door-to-door to educate residents about prevention efforts and monitor problem areas, he said.
