Chronic Wasting Disease (CWD) is a disease of the nervous system that results in distinctive lesions in the brain. CWD affects elk, white-tailed deer, and mule deer, but has not been documented in livestock or humans. The cause is unknown and no treatment is available. Infected deer and elk can appear robust and healthy in the early stages of CWD; it may take several years before they show clinical signs, after which the disease is fatal. Direct contact between infected and non-infected animals is the most likely route of transmission, but other possibilities are under consideration, including contamination of soil by excreta from infected animals.
USGS is collaborating with federal, state, and private partners to address CWD issues. These joint efforts have addressed immediate needs – developing cooordinated plans, establishing diagnostic capabilities to identify the disease, modeling and analyzing effects of the disease, and Preparing to sample lymph nodes for CWD testing at the Park Falls, Wisconsin, sampling site.

New initiatives, based on the plans already developed, will seek to refine our information about the disease and identify effective management strategies for CWD control and eradication.
