Chronic wasting disease is a fatal, infectious nervous system disease of deer, moose, elk and reindeer/caribou. It belongs to the family of diseases known as transmissible spongiform encephalopathies (TSEs) or prion diseases. CWD occurs only in members of the cervid or deer family -- both wild and captive. The Wisconsin DNR began monitoring the state's wild white-tailed deer population for CWD in 1999. The first positives were found in 2002.
