West Nile virus activity confirmed in Concord, Danville, and Byron

CONCORD, CALIFORNIA - -  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." 

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 or by visiting the California Department of Public Health's website. All reports are crucial.
Since 2005, 56 people in Contra Costa County have been diagnosed with West Nile virus. In 200 6, two people died from the disease. For a current list of West Nile virus activity this year, visit this page on the District's website.   For human case information, please contact Contra Costa Health Services at 888-959-9911.
