Mosquitoes collected in Fullerton have tested positive for the West Nile Virus, the OC Mosquito and Vector Control District has reported.

The West Nile Virus can cause serious symptoms for humans, even death, though in most cases is more mild and flu-like. It is primarily transmitted to humans through the bite of infected mosquitoes, which acquire the virus when feeding on infected birds.

Orange County has not reported any human cases of the virus as of July 31. The sample mosquitoes that tested positive were found near the cross streets of Rosecrans Avenue and North Gilbert Street.

“Mosquitoes testing positive for West Nile virus is an indication that the virus is circulating in the community,” Amber Semrow, director of scientific and technical services for Vector Control, said. “Fullerton is historically a high-risk area for West Nile virus activity.”

Wearing mosquito repellent is important, Heather Hyland, director of communications at the district, said. “That’s the best way to protect yourself, is to wear something that’s going to deter them from biting you.”

Folks who don’t like using repellent can opt for wearing loose, long-sleeve clothing, she said.

To protect one’s home from mosquitoes, Vector Control officials recommend people regularly drain containers filled with water, clean and scrub bird baths and pet water bowls and dump water from potted plant saucers.

“Residents really need to take that responsibility to take charge of their yard, look around for any form of water,” Hyland said, “If they feel like they’re still seeing mosquito activity around their homes, they can always call us for an inspection.”

Vector Control staff will continue to conduct surveillance, inspections, and control measures for mosquitoes in the area to prevent additional mosquito breeding.
