It is a transmissible spongiform encephalopathy (TSE) of mule deer, white-tailed deer, elk (or wapiti), and moose (elk in Europe).
Abstract. Chronic wasting disease (CWD) of deer and elk is endemic in a tri-corner area of Colorado, Wyoming, and Nebraska, and new foci of CWD have been detected in other parts of the United States.  AIDS wasting is the involuntary loss of more than 10% of body weight, plus more than 30 days of either diarrhea, or weakness and fever. Wasting is linked to disease progression and death.  Chronic Wasting Disease (CWD). Chronic wasting disease (CWD) is a disease of the nervous system in deer and elk that results in distinctive brain lesions. It continues to be a major issue for wildlife scientists throughout the Nation, and a key focus for research at the USGS National Wildlife Health Center (NWHC).  CWD is a disease found in some deer, elk and moose populations. CWD damages portions of the brain and typically causes progressive loss of body condition, behavioral changes, excessive salivation and death. The cause of the disease is suspected to be a type of prion (protein infectious particle) that is found in some tissues of infected animals. Wasting Syndrome: Introduction. Wasting Syndrome: AIDS related wasting syndrome is the involuntary loss of more than 10% of the body weight plus more than 30 days of either diarrhoea or weakness and fever. It is linked to disease progression and death.  From Wikipedia, the free encyclopedia. Chronic wasting disease (CWD) is a transmissible spongiform encephalopathy (TSE) of mule deer, white-tailed deer, elk (or wapiti), and moose (elk in Europe). To date, CWD has only been found in members of the deer family. First recognized as a clinical wasting syndrome in 1967 in mule deer in a wildlife research facility in northern Colorado, USA, it was identified as a TSE in 1978 and has spread to free-ranging and captive populations in 23 US states and two Canadian provinces. Chronic wasting disease is a fatal neurological disease found in cervids (deer and elk). It belongs to the family of diseases known as transmissible spongiform encephalopathies (TSEs) or prion diseases.  A. A. A. AIDS wasting syndrome occurs when you have AIDS and lose at least 10% of your body weight -- especially muscle. You may also have at least 30 days of diarrhea or extreme weakness and fever that's not related to an infection. Not a specific disease, AIDS wasting syndrome is a poorly understood condition of AIDS (acquired immunodeficiency syndrome). Chronic wasting disease (CWD) is a prion disease that affects North American cervids (hoofed ruminant mammals, with males characteristically having antlers). The known natural hosts of CWD are mule deer, white-tailed deer, elk, and moose.
