The discovery of chronic wasting disease in three wild deer taken during the 2012 hunting season here in south-central Pennsylvania will impact many hunters in our region during the upcoming hunting seasons, beginning with opening of archery season just two weeks from now. CWD is a disease that attacks the central nervous system of species in the deer family, including whitetails, mule deer, elk and moose. CWD is contagious, and when an animal becomes infected with CWD, the disease is always fatal. There is no way to test live animals for CWD, nor is there any vaccine or cure for it. Once CWD gains a foothold in a given area, the disease always gets worse and always spreads.
