The Rockland County Department of Health says for the first time this season a group of mosquitoes has tested positive for West Nile Virus. The infected mosquitoes came from a trap in Ramapo earlier this month. No human cases have been reported thus far. A bite from a West Nile Virus-infected mosquito can cause serious illness, and in some cases, death. Although a person’s chances of getting sick are small, those over age 50 are at the highest risk. If you think you have symptoms of West Nile Virus, see your doctor right away.
