What Is CWD? CWD is a transmissible spongiform encephalopathy (TSE) that is found in deer and elk. It is believed to be caused by a mutated protein, called a prion that attaches to, and transforms healthy brain proteins into disfigured mutations that lead to a deterioration of the brain, and ultimately death of the animal. CWD is similar but different from scrapie ( a disease found in domestic sheep), Bovine Sponfigorm Encephalitis (also referred to as "mad cow" disease) and Creutzfeld-Jakob disease (a TSE found in humans.) While similar to these diseases, there is no known causal link between CWD and other TSEs of animals or people. There is currently no evidence to indicate that CWD can be transmitted from elk and deer to livestock or humans.
Signs of an Infected Game Animal Clinical signs of CWD include stumbling, poor body condition, excessive drinking and salivation and difficulty running. If you observe such signs, please report the sighting to your nearest NDOW office. Learn how you can help. Sampling Efforts and Check Stations CWD has not been detected in Nevada, yet sampling efforts in the state are ongoing. As of August 2004, the closest state to detect CWD in wild deer herds is Utah. Nevada began routine testing for CWD in 1998. Through 2003, a total of 725 deer and 251 elk samples were tested and found negative for the disease. Samples were collected from a variety of methods, including contacts in field between NDOW biologists and hunters, check stations, road kills, and inspection at meat processing facilities. The majority of the samples came from hunter-harvested animals. Biologists are keeping a close eye on population numbers and will continue to analyze samples by deer and elk game management units. In 2004, targeted mailings were sent to hunters with tags in management units where increased samples were needed by NDOW. Test results of deer and elk samples collected through December 2004 will be publicly available by April 2005.
Your observations of animals showing possible signs of CWD are extremely valuable to NDOW biologists in the effort to monitor CWD status in Nevada. Clinical signs of CWD include stumbling, poor body condition, excessive drinking and salivation and difficulty running. If you observe such signs, please report the sighting to your nearest NDOW office or to the Operation Game Thief number listed below. Hunters who would like to donate a sample from their deer or elk for Nevada’s CWD sampling effort may do so by bringing the head of the animal to one of the locations listed below during normal business hours. Hunters who are having taxidermy work done on trophy animals may not want to donate a sample since the process may damage the cape. Carcass Disposal:
