You know it always gets worse before it gets better. I'm afraid you might have to shoot a lot of deer and dispose of the meat, unless you can avoid the diseased stuff.
I heard the similar CJD in England was NOT XMIT'd by eating bad meat. The stomach acids should kill any proteins before they ever get to the blood stream.
We need more study and a solution that will get the herds back to health.
Remember the clowns who sold billions of drugs a year to treat ulcers, caused by a bacteria -- something you could see with any good microscope. We need somebody who can treat this and eliminate it.
Seriously though, last I checked (last season), the demand for elk permits in Colorado, Wyoming, and Idaho was very high. If somebody had contracted the human version of CWD, that would have made big news throughout the hunting world because of the number of guides operating in those states.
