According to the Missouri Department of Conservation, Chronic Wasting Disease could affect 520,000 hunters and 12,000 jobs in the state. CWD is 100-percent fatal.
Epizootic Hemorrhagic Disease is also deadly in deer, though not all are affected by it. EHD is more prevalent during droughts in the summer and fall.
Dave Carlisle of the MDC discusses the differences between CWD and EHD in the video above.
