Mosquitoes test positive for West Nile virus in Orange County

VECTOR CONTROL

The Orange County Mosquito and Vector Control District has confirmed that mosquitoes collected in the cities of Anaheim and Garden Grove have tested positive for West Nile virus. These are the first samples to test positive in the county this year. A dead bird recovered in Garden Grove has also tested positive for the virus.

West Nile virus is primarily transmitted to humans through the bite of infected mosquitoes, which acquire the virus when feeding on infected birds. As of publication, Orange County has not reported any human cases of West Nile virus.

District staff will continue to conduct surveillance, inspections, and control measures for mosquitoes in the area to prevent additional mosquito breeding. The district will also post West Nile virus advisory signs alerting residents of virus activity in affected areas.

“Everyone in Orange County should do their part to prevent mosquitoes,” district spokesperson Brian Brannon said. “Dumping and draining standing water is the most effective and environmentally friendly way to rid mosquitoes from our communities.”

To prevent mosquito bites and mosquito reproduction:

• Dump and drain containers holding water at least once a week.

• Clean and scrub bird baths and pet water bowls.

• Wear repellent containing DEET, Picaridin, IR3535, or oil of lemon eucalyptus.

• Close all unscreened doors and windows to prevent mosquitoes from entering; repair broken or damaged screens.

• Wear light-colored, loosefitting, long-sleeved shirts, and long pants while outside at dawn and dusk.

Symptoms of the virus include fever, headache, body aches, rash, swollen lymph nodes, joint pains, vomiting and diarrhea. Older adults are at greater risk of developing severe illness from the virus.
