Orange County health officials have reported the detection of mosquitoes carrying the West Nile virus in Santa Ana. The Orange County Mosquito and Vector Control District identified the affected area as being bordered by Garden Grove Boulevard, the Santa Ana River, Trask Avenue, and Fairview Street.

Inspectors are actively investigating known mosquito breeding grounds and seeking out any potential new sources in the area.

This detection follows recent reports of West Nile virus in Ventura, Los Angeles, and Riverside counties. Although no human cases have been confirmed in Orange County, symptoms can develop days after being bitten by an infected mosquito. Symptoms may include fever, headaches, and body aches, although many people may remain asymptomatic.

To minimize the risk of infection, officials advise residents to limit outdoor activity at dusk and dawn, wear long sleeves and pants, apply insect repellant, and ensure windows and doors are properly screened. Mosquito season in Southern California typically runs from May through October.
