Utilizing the state’s virus-modeling program, the Contra Costa Mosquito & Vector Control District has identified southeast Brentwood as a high risk area for West Nile virus (WNV) infection. The area is Central Boulevard to the north, Guthrie Lane to the east, Creek Road and Claremont Drive to the west, and Payne Avenue to the south. Antioch remains at high risk for WNV infection as well.

In addition, virus-positive dead birds from Antioch and Walnut Creek, as well as two virus-positive squirrels from Antioch are being reported.

“Utilizing a modeling system to predict where human cases may occur is a huge advantage,” said Deborah Bass, public affairs manager with the Contra Costa Mosquito & Vector Control District. “It allows our District to put forth a concentrated effort into the high risk areas in our county in order to protect our residents’ health.”

In Contra Costa County to date this year, there have been eight dead birds (one from Alamo, one from Knightsen, one from Walnut Creek, and five from Antioch), six groups of mosquitoes (one from Holland Tract and five from Antioch), and two squirrels from Antioch that have tested positive for West Nile virus. So far this year, no human cases have been reported.

District officials continue to urge property owners to routinely check their yards, to dump mosquito water sources, and to properly maintain their water features. Abandoned or neglected swimming pools are especially worrisome as they can produce hundreds of thousands of mosquitoes and affect residents up to a five-mile radius.

Contra Costa Mosquito & Vector Control District is located at 155 Mason Circle in Concord. Call the District to report mosquito problems at 925-771-6195, or visit their office between 8 a.m. and 4:30 p.m. to get FREE mosquitofish for ornamental ponds or horse troughs.

TO ALL:
Please report dead birds or dead squirrels to 877-968-2473. This will help them to pinpoint problem areas for the virus so they can focus their control efforts on those spots. That will help a lot to control the virus. Thanks. /Gary
