They don't really know how it spreads. Here is a link from the WV DNR:
WV Chronic Wasting Disease. Saliva is one theory.
They have really locked down the rules around here, as the CWD keeps spreading. We can no longer take carcasses across the state line, either direction. The deer my Virginia friends shoot have to be butchered on the Virginia side.
If there is a good part to the CWD, it is that it allows us to thin the herds through a lot of special antler-less hunting days. Even so, we still have large herds of deer. We had 12 in the front yard the other morning. I'm sure that the high concentrations of deer in this area doesn't help the CWD.
