First Evidence Found Of West Nile Virus In Contra Costa County

MARTINEZ, CA -- Three chickens from the Contra Costa Mosquito & Vector Control District's sentinel chicken flock in Martinez have tested positive for antibodies against West Nile virus, the district reported Friday.

"This is the first evidence of West Nile virus activity in the central part of our county this summer," Steve Schutz, the district's scientific programs manager, said in a statement.

Schutz suggests residents county-wide take precautions against mosquitoes, such as removing areas of standing water where the insects flourish, using repellents and avoiding the outdoors during dawn and dusk hours when mosquitoes are prevalent.

The district also urges people to report dead birds. Ravens, jays, crows and magpies are highly susceptible to the virus and may die if infected. Residents who find a dead bird may call (877) WNV-BIRD or (877) 968-2473.

Since 2005, 63 Contra Costa County residents have been diagnosed with West Nile virus. In 2006, two people died from the disease.
