Brentwood remains high risk area; Antioch’s risk lowered.

The Contra Costa Mosquito & Vector Control District is reporting one horse, one group of mosquitoes and six dead birds that have tested positive this past week for West Nile virus in the county. The horse and the mosquitoes were from Brentwood. Two of the birds were from Brentwood, two from Antioch, one from Concord, and one was from Danville. Brentwood remains a high risk area for West Nile virus infection in Contra Costa County.

In Contra Costa County to date this year, four people, 79 dead birds, 27 groups of mosquitoes, nine squirrels, 14 chickens, and two horses have tested positive for West Nile virus.

HORSES:

“This case is an important reminder to horse owners to get their horses vaccinated,” said Deborah Bass, public affairs manager with the District. “Horses are highly susceptible to the virus and nearly half of the horses who get this disease die.”

POOLS:

The District is urging all residents to maintain water features in their yards and to report abandoned or neglected swimming pools. Abandoned or neglected swimming pools are a significant source of mosquitoes in Contra Costa and each one can produce hundreds of thousands of mosquitoes and affect residents up to a five-mile radius. Infected mosquitoes can transmit West Nile virus, a debilitating and potentially fatal disease.

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. Mosquitofish are also available at City of Antioch Corporation Yard, 1201 W. 4th Street, Antioch, CA, Monday through Friday (except holidays) from 7 a.m. to 4 p.m.

People wishing to be notified about adult mosquito fogging or spraying have several options. They may visit the District’s Web site at http://www.ccmvcd.dst.ca.us and opt to receive the notifications automatically by e-mail, they can view information on the District Web site, or they may phone the District for a recorded message at 925-771-6195.

    Did you know that the water channel under Clayton Rd & Diablo street in CONCORD (near Longs & Bart) is NOT moving/running! It is green with LARGE algae beds and a great mosquito growing bed.
    Why is it at a stand still? Where’s the M. Abatement clean up department?

    Diane:
    I’m passing this information along to the Mosquito and Vector Control District folks in Concord. They probably didn’t know about this. Thanks for the alert. /Gary
