  1. CWDChronic Wasting Disease By Kevin Moran

  2. Name • CWD or chronic wasting disease which is a transmissible disease caused by a spongiform encephalopathy of the cervid family.

  3. First Discovery • First discovered in 1967 in a herd of mule deer in Colorado. • Was discovered when these mule deer died off within hours of each other. 48 to be exact.

  4. What Causes it? • CWD is caused by prions which are infectious proteins without associated nucleic acids. • Most deer pick the disease up from wetland areas and then have the capability of transmitting it to other deer from their saliva.

  5. Effects • Poor body condition • Extreme salivation • Lesions on the brain • Wide based stances

  6. Pictures of infected cervids

  7. Control Factors • There is no known cure and really no way to completely prevent it all together. • The best practice is to kill and get rid of any infected animals as quick as possible once detected.

  8. How dangerous is it • It has been determined that deer can pass this disease on to other deer at extraordinary rates, making it very deadly. If one deer gets infected in a herd, the others are vulnerable to exposure. • This means that total herds can get wiped out just like the one in Colorado.

  9. Preventions • The disease cannot be carried over to humans as of right now, but there is a warning out to hunters to always wear safety gloves when field dressing a deer because of the risk factor. • For captivity deer, when petting them always wash your hands after words to prevent spreading the disease
