Orange County Faces West Nile Surge as Mosquito Sprays Roll Out
A dangerous West Nile virus surge is sweeping 13 Orange County cities, with 38 positive mosquito samples this season and Fullerton accounting for about 40% of cases. Officials have begun overnight spraying in a 4.5-square-mile area of Fullerton, while residents are urged to eliminate standing water, clean bird baths and pet bowls, fix screens, and use DEET- or picaridin-based repellents. West Nile is spread by mosquitoes; most people recover or have mild symptoms, but severe infections can cause encephalitis or meningitis, particularly in older adults or those with weakened immune systems.
