The Contra Costa Mosquito & Vector Control District confirmed today that three dead birds and two groups of mosquitoes tested positive for West Nile virus. Two dead birds were from Concord and one was from Antioch. The mosquitoes were trapped in Byron and Brentwood.
“We had several days of hot weather over the past week and saw a bit of a resurgence of West Nile virus activity,” said the District’s Scientific Program Manager Steve Schutz, Ph.D. “This is a good reminder that even though Labor Day has passed, the mosquito season is not quite over yet, and we need to continue to take precautions to prevent mosquitoes and mosquito bites.”
Visit the District’s website to learn of all West Nile virus activity in Contra Costa County this year, or to receive automatic adult mosquito fogging notifications should they be scheduled.
Residents are urged to help reduce their risk of contracting mosquito-borne diseases by following these guidelines:
- Dump or drain standing water. Mosquitoes can’t begin their lives without water.
- Defend yourself – use repellents containing DEET, Picaridin, or Oil of Lemon Eucalyptus.
- Avoid being outdoors when mosquitoes are present, typically dawn and dusk.
- Maintain neglected swimming pools . Just one can produce more than 1 million mosquitoes and affect people up to five miles away.
- Report dead birds to the state hotline: 1-877-968-2473. All reports are crucial.
Since 2005, 55 people in Contra Costa County have been diagnosed with West Nile virus. In 2006, two people died from the disease.
