New West Nile Virus Infections Reported in Contra Costa Co.

CONTRA COSTA CO. (BCN)–West Nile virus activity has continued throughout Contra Costa County this month with new reports of infected people, mosquitoes, and birds, according to the Contra Costa Mosquito and Vector Control District.

The district reported Friday that a new group of mosquitoes from an agricultural area west of Discovery Bay tested positive for West Nile virus.

A dead bird found in Alamo also tested positive for the virus, along with three people from undisclosed locations within Contra Costa County.

“These people were most likely infected in August or September, with symptoms presenting themselves usually three to 14 days later,” Dr. Steve Schutz, the district’s scientific program manager, said in a statement.

“That, combined with doctor’s visits, a thorough investigation including travel history, testing and notification to the various agencies, takes time and is why cases are announced at a later date,” Schutz said.

Since 2005, 52 people have been diagnosed with West Nile virus in Contra Costa County, with two people dying from the disease in 2006.

The Contra Costa Mosquito and Vector Control District advises residents to help reduce the risk of contracting mosquito-borne diseases by dumping or draining standing water, using bug repellents and avoiding the outdoors when mosquitoes are present.

Neglected swimming pools, which can breed millions of mosquitoes and affect people for up to a five-mile radius, can be reported by calling (925) 771-6195.

Dead birds can be reported to the state hotline at (877) 968-2473.
