The West Nile virus was located in three separate samples of mosquitos taken from the Stockton area on Friday.
The San Joaquin County Mosquito and Vector Control District discovered evidence of the virus in the 95207 and 95209 zip codes.
District spokesman Aaron Devencenzi told The Mercury News that the surveillance system is designed for “the earliest possible detection of the West Nile virus positive mosquitos.”
But he assured that the district is taking all the necessary precautions and urges residents to avoid mosquito bites during this time.
Mosquitoes repopulate in standing water, so it is advised that residents remove all sources of standing water on their property. Residents are also advised to use insect repellent approved by the U.S. Environmental Protection Agency, wear protective clothing, and decrease their time spent outside at dawn and dusk when mosquitos are most active.
Devencenzi affirmed that “with this find, the district will be increasing mosquito control efforts to further reduce the mosquito population in these areas.”
All residents may report mosquito bites to the San Joaquin County Mosquito and Vector Control District at (209) 982-4675.
