The Berks County Conservation District is warning residents after West Nile virus was detected in Shillington and Reading, Pennsylvania.

GRAND JUNCTION, Colo. (KKCO) - Officials have detected the West Nile Virus in Garfield County. Certain mosquito species found in the county — especially in the western portion near Parachute, Battlement Mesa, Silt, and Rifle — can carry and transmit the virus.
