The most obvious sign of CWD is progressive weight loss. Numerous behavioral changes also have been reported, including decreased social interaction, loss of What causes chronic wasting disease?

Chronic wasting disease is caused by a misfolded protein called a prion. All mammals produce normal prions that are used by cells, then degraded and eliminated, or recycled, within the body. When disease-associated prions contact normal prions, they cause them to refold into their own abnormal shape.

These disease-associated prions are not readily Filter Total Items: Year Published: Chronic wasting disease—Research by the U.

Carlson, Christina M. Camille ; Nguyen, Natalie T. Carlson, C. Geological Survey: U. CWD is fatal to animals and there are no treatments or vaccines. To date, there have been no reported cases of CWD infection in people.

However, some animal studies suggest CWD poses a risk to certain types of non-human primates, like monkeys, that eat meat from CWD-infected animals or come in contact with brain or body fluids from infected deer or elk.

These studies raise concerns that there may also be a risk to people. Since , the World Health Organization has recommended that it is important to keep the agents of all known prion diseases from entering the human food chain. Error processing SSI file.
