York County officials are warning residents to use insect repellent and cover exposed skin while outdoors after a mosquito pool tested positive for West Nile virus recently.
York County Mosquito Control found West Nile virus in a sample in the Penniman area of the upper county, York County spokeswoman Gail Whittaker said in an email.
Mosquito Control regularly tests mosquito samples collected from various areas of the county. There have been no reported cases of West Nile in humans or other animals.
To prevent the spread of mosquito-borne illness, the county conducts mosquito spraying between late spring and early autumn.
