West Nile virus detected in Seal Beach

VECTOR CONTROL

The Orange County Mosquito and Vector Control District has confirmed mosquito samples infected with West Nile virus (WNV) in the City of Seal Beach, the district announced Sept. 3. The surveillance traps were set in an area of Seal Beach Boulevard between the 405 Freeway and Westminster Boulevard.

Inspectors will check known sources of mosquito breeding in the Seal Beach area and to try to identify any unknown sources. West Nile virus advisory posters will be placed in the affected areas. If mosquito samples in the area continue to test positive, adult mosquito control may be conducted in the future.

On Aug. 28, the district announced that a Huntington Beach resident tested positive for West Nile virus, becoming the first human case of the virus in Orange County this year. In 2023, Orange County reported seven human West Nile virus infections.

The district advises residents to take precautions and wear mosquito repellent when mosquitoes are most active: dawn and dusk. LWers should check for standing water and protect themselves from mosquito bites. West Nile virus affects the central nervous system. Of those who are infected, approximately 80% show no symptoms.

The approximately 20% of people who do show symptoms may experience fever, headache, body aches, nausea, vomiting and sometimes swollen lymph glands or a skin rash.

People should take precautions at dawn and dusk, when mosquitos are most active.
