The Orange County Mosquito and Vector Control District (OCMVCD) has confirmed mosquito samples infected with West Nile virus (WNV) in the City of Fullerton.

The West Nile Virus can cause serious symptoms for humans, though in most cases is more mild and flu-like. According to the Centers for Disease Control and Prevention, “About 1 in 5 people who are infected develop a fever with other symptoms such as headache, body aches, joint pains, vomiting, diarrhea, or rash. Most people with febrile illness due to West Nile virus recover completely, but fatigue and weakness can last for weeks or months.” It is primarily transmitted to humans through the bite of infected mosquitoes, which acquire the virus when feeding on infected birds.

OCMVCD inspectors will be out in the area to check known sources of mosquito breeding and to try to identify any unknown sources. West Nile virus advisory posters will be placed in the affected areas, and if there are continued positive mosquito samples, adult mosquito control may be conducted in the future.

At this time, OCMVCD asks to please take precautions and wear mosquito repellent when mosquitoes are most active (dawn or dusk). Additionally, regularly drain containers filled with water, clean and scrub bird baths and pet water bowls and dump water from potted plant saucers.
