I was looking at the map that was on the article Jake posted. Almost all of the hot areas have expanded and are all tightly connected with no gaps. There are a few isolated spots but suspect they came from a game farm in the area that imported infected animals. It is clear that as time goes on this disease will spread and eventually consume the whole country. This thing has been around and documented since the 1960's when it started at a game farm in Colorado. If this were a human disease it would have to be stopped through whatever methods science can come up with. What is hard for me to understand is why no universal things have happened to stop it. States still allow canned hunting facilities to remain open when it has shown that they often contribute to the spread of CWD. People, in some locations are still able to hunt in infected areas and bring the whole carcasses back to a home state thus transporting the prions from one place to another. They discard the carcass after butchering which transfers those prions into the earth and later gets into the native animals through plant growth. Once there is a documented crossover to humans it will be a whole new ballgame. Perhaps then a solution will happen on a national level.
