West Nile virus activity confirmed in Concord, Danville, and Byron
The Contra Costa Mosquito & Vector Control District confirmed today that four dead birds and one group of mosquitoes tested positive for West Nile virus. Two dead birds were found in Concord and two dead birds were found in Danville. The mosquitoes were trapped in Byron.
“It’s common to get dead birds that test positive for the virus in the 680 Corridor at this time of the year,” said the District’s Scientific Program Manager Steve Schutz, Ph.D. “However, the risk of West Nile virus should decrease county-wide as the overnight temperatures drop.”
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.
