The Contra Costa Mosquito & Vector Control District confirmed today that two groups of mosquitoes tested positive for West Nile virus. One group was found near Knightsen and another group was found in Antioch. Mosquitoes that carry West Nile virus can spread the disease when they bite people.
“It’s important to wear mosquito repellent,” said Deborah Bass, public affairs manager with the District. “Summertime and mosquito repellent go hand in hand.”
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.
