Since chronic wasting disease first turned up in the wild in 1981, about 100 cases have been reported in wild mule deer, white-tailed deer, and elk, and only eleven of those cases were in Wyoming.
At this point, chronic wasting disease remains rare in the wild, and it is confined to a few hunt areas in northcentral Colorado and southeastern Wyoming.
Chronic wasting disease can take several years to claim its victims, and the vets running the studies expect to continue them for as much as a decade.

 APHIS | News
Based on epidemiology, transmission of CWD is thought to be lateral or from animal to animal; although maternal transmission may occur, it appears to be relatively unimportant in maintaining epidemics.
CWD in free-ranging deer in Nebraska was detected in 2000/2001; more intensive surveillance to better define the prevalence and distribution of the disease in free-ranging deer in Nebraska is underway.
All of these agencies are committed to limiting the distribution of the disease in free-ranging deer and elk to the current localized area and decreasing its occurrence in both the free-ranging and farmed deer and elk populations.

 TPWD: Chronic Wasting Disease Fact Sheet
CWD is an untreatable, fatal neurological (brain and nervous system) disease found in deer and elk in some geographic locations in North America.
While CWD is similar to Bovine Spongiform Encephalopathy (BSE or "mad cow disease") in cattle and scrapie in sheep and goats, there is no known relationship between CWD and any other TSE of animals or people.
CWD is known to infect free-ranging deer and elk in areas of Colorado, Wyoming, Nebraska, South Dakota, Utah, New Mexico, Wisconsin, Illinois, New York, West Virginia, and Saskatchewan.

 Nebraska Game and Parks Commission - Chronic Wasting Disease Guide - Introduction
Chronic Wasting Disease, often referred to as CWD, appears to be a prion disease that attacks the central nervous system and causes fatal damage to the brain of white-tailed deer, mule deer, and Rocky Mountain elk.
CWD is similar to, but significantly different from, scrapie (documented in domestic sheep for over 400 years), Bovine Spongiform Encephalopathy (BSE and often referred to as mad cow disease) and variant Creutzfeldt-Jakob disease (vCJD), and Creutzfeldt-Jakob disease (CJD).
It was once thought that the disease occurs naturally in less than 5 percent of the wild deer population and in about 1 percent of the wild elk population, largely based on studies conducted in the infected areas of Colorado and Wyoming.

CWD causes a characteristic spongy degeneration of the brain leading to loss of body condition, altered behavior, and death.
CWD was first recognized as a clinical "wasting" syndrome in 1967 in mule deer at a wildlife research facility in northern Colorado.
The disease does not appear to limit free ranging elk or deer population numbers in the wild, though longer term studies are needed to evaluate long-term effects.

Chronic Wasting Disease (CWD), a disease of deer and elk, is one of the transmissible spongiform encephalopathy (TSE) diseases, i.e.
CWD is thought to be transmitted primarily orally through contaminated feed and water from CWD infected animals, particularly the end-stage clinical CWD animal.
Chronic wasting disease pathogenesis is not fully understood, although pathogenesis studies have shown when elk are infected orally with CWD-infected material, the tonsils and head lymph nodes will have PrPres present, by immunohistochemical (IHC) staining, two months after oral dosage.

Chronic Wasting Disease (CWD) is a rare, fatal, neurological disease found in cervids, members of the deer family.
It is a transmissible disease that slowly attacks the brain of infected deer and elk, causing the animals to progressively become emaciated, display abnormal behavior and invariably results in the death of the infected animal.
CWD is one of a group of transmissible spongiform encephalopathies (TSEs) that include scrapie in sheep and goats, transmissible mink encephalopathy of ranched mink, and bovine spongiform encephalopathy, known as "mad cow disease", in cattle.
