It is worth noting that a number of other research projects regarding CWD in cervids are in progress. TSE is the whole group of diseases, of which CWD is one. All TSE diseases have the characteristic of creating holes in the brain'making the brain look like a sponge. Clinical signs of CWD include loss of body condition, behavioral changes, excessive salivation, changes in facial expression, and hyperaesthesia. CWD was first recognized at a Colorado Department of Wildlife facility in 1967 and was diagnosed in free-ranging elk in 1981.
Prions are a newly recognized group of disease- causing agents.
Anyone can put information on the Internet. Unfortunately, in the case of CWD, a lot of the information on the Internet is false. At this time, it is not known how CWD is spread. At this time, it is not known when, in the course of the disease, it can be spread to other animals. At this time, it is unknown how long the agent persists in the environment.
