Chronic Wasting Disease
Chronic Wasting Disease is a progressive, fatal, neurological disease found in a small percentage of cervids (deer and elk). CWD belongs to the family of diseases known as transmissible spongiform encephalopathies (TSEs).
CWD was first described clinically as a wasting syndrome in captive deer held in a Colorado wildlife research facility in 1967. CWD was detected in free-ranging deer and elk in northern Colorado and adjacent sections of southeast Wyoming in the mid-1980s. Since then, CWD has also been found in captive herds in South Dakota, Nebraska, Oklahoma, Kansas, Colorado, Montana and Saskatchewan, Canada. CWD has also been found in free-ranging deer in South Dakota, New Mexico, Nebraska, Wisconsin, and Saskatchewan.
