Wild Rivers Whitetails said:EHD is far more deadly to deer than CWD! They can document losses to EHD every year and there are usually plenty. Anthrax in Texas also gets a lot of deer, but CWD has been made the boogie man of whitetails. My guess is that it has been around a lot longer than anyone realizes but it takes a long time to kill an animal and deer, especially bucks in the wild don't live that long.
