RISK GROWS AS BIRDS, MOSQUITOES TEST POSITIVE FOR WEST NILE VIRUS 
Take Important Steps Now to Avoid Mosquito Bites
CONCORD, CALIFORNIA - The Contra Costa Mosquito & Vector Control District is reporting mosquitoes from Oakley and Discovery Bay and two dead birds from Discovery Bay have tested positive for West Nile virus. This is the fifth group of mosquitoes and the third  dead bird from Contra Costa County so far this year to test positive for the virus.  

According to the District's Scientific Programs Manager Steve Schutz, Ph.D., "West Nile virus activity typically peaks in August and September, when baby birds have left their nests and mosquitoes begin to feed on humans more often. This puts people at higher risk of virus transmission and so it's important for Contra County residents to take steps now to avoid mosquito bites."

Mosquitoes that can transmit West Nile virus are active at dawn and dusk. 

Steps to take now to avoid mosquito bites:
  • Stay indoors in the evening when mosquitoes can be present 
  • Wear mosquito repellent when outside

Repellents containing DEET, Picaridin, or Oil of Lemon Eucalyptus are most effective and are recommended by the Centers for Disease Control and Prevention (CDC).


In addition to staying indoors and wearing repellent when outdoors, the District encourages residents to reduce the risk of contracting West Nile virus and other mosquito-borne diseases by:
  • Dumping or draining standing water to prevent mosquitoes. Most mosquitoes can't start their lives without water.
  • Reporting  dead birds to the state hotline: 1-877-968-2473. Birds are often the first sign of disease transmission in a particular area. Ravens, jays, crows, and magpies can be susceptible to the virus, and may die if infected. 
Even if the birds are not tested, the reports alone yield crucial information to protect public health.
