Chronic Wasting Disease (CWD)
Chronic Wasting Disease (CWD) is a neurological disease in deer, elk and moose that attacks the brain, causing weight loss, abnormal behavior, and, eventually, death. CWD belongs to a group of diseases called transmissible spongiform encephalopathies (TSEs). CWD is similar to scrapie in sheep and bovine spongiform encephalopathy (BSE) in cattle, but CWD is a distinct disease known only to affect members of the deer family.
Scientists think CWD is transferred from one animal to another through contact with saliva, feces, and urine, but the disease may also be spread indirectly from the environment to susceptible animals.
