Pennsylvania Equine West Nile Virus Up-Date 2011
Posted: December 2, 2011
West Nile virus is a mosquito-borne disease that can cause encephalitis, a brain inflammation. Infected mosquitoes pass the virus onto birds, horse and people. West Nile virus cases in Pennsylvania occur primarily in the mid-summer or early fall, although mosquito season is usually April-October. State reports have shown that we have several hot spots located in Pennsylvania.
