It was first identified in wild elk and mule deer and white-tailed deer in the early 1980s in Colorado and Wyoming, and in farmed elk in 1997. CWD belongs to a group of diseases known as Transmissible Spongiform Encephalopathies (TSEs), in which the infectious agents are known to be the prion protein, a normal protein that misfolds and destroys the brain. Chronic Wasting Disease: Novel Type of Chronic Wasting Disease Detected in European Moose (Alces alces), Norway. Chronic wasting disease (CWD), more commonly referred to as Zombie deer disease is a transmissible spongiform encephalopathy (TSE) affecting deer.TSEs are a family of diseases thought to be caused by misfolded proteins called prions and includes similar diseases such as BSE (mad cow disease) in cattle, Creutzfeldt-Jakob disease (CJD) in humans and scrapie in sheep. Surveillance efforts began in 1996 and, to date, 27,863 cervids have been sampled and tested for CWD. The EU then decided on a general surveillance in six Member States, including Sweden.

While both North America and Europe have detected chronic wasting disease (CWD) in cervids such as deer, the two continental strains are distinct, reports a study yesterday in Proceedings of the National Academy of Sciences ( PNAS ). It is widely accepted that feeding the cattle, which are normally herbivores, with the remains of other cattle in the form of meat and bone meal, caused the bovine spongiform encephalopathy, probably from the contamination of the meal from sheep with scrapie that was processed in the same slaughterhouse. The disease spread to South Korea when a shipment of live elk carrying presumably the infection was brought into the country for farming in the late 1990s. It is the first time that CWD is detected in Europe, and the first time it is detected in this species since previously it was thought to be restricted to mule deer (Odocoileus hemionus), white-tailed deer (O. virginianus), elk (Cervus elaphus nelsoni) and moose (Alces alces shirashi).
