Point of origin in lots of states has been deer enclosures. In fact, the very first case on record was inside an enclosure.
Way back in 1967, CWD was first identified in captive mule deer at the Colorado Division of Wildlife, Foothills Wildlife Research Facility in Fort Collins, Colorado. It wasn’t until 1981 that CWD was found in a wild animal, an elk also in Colorado, marking the first documented case of CWD in a wild cervid. All cervids (antlered ruminants) (elk, moose, caribou, whitetails, blacktails, mule deer, etc.) are susceptible to it.
The first documented case in whitetails occurred in 2001 when South Dakota discovered CWD in wild whitetail deer. The Wisconsin Department of Natural Resources detected CWD in wild whitetail deer, the state's first documented case of CWD in 2002. That same year CWD was identified in New Mexico (wild mule deer), Minnesota (captive elk), Illinois (wild whitetail), and Alberta (captive whitetail).
Today, 21 states and two Canadian provinces have confirmed cases of CWD. At least 19 have cases in wild cervid populations.
