It could be spread deliberately but there's no need, it's doing a great job by itself. Some was spread accidentally by people transferring different types of deer for deer farms, where people go to fenced in areas to hunt. CWD escaped the enclosure, either by deer escaping or by being eaten by a predator. Wolves and other predators can transmit it, supposedly without being affected by it.
It can be spread through feces and urine. It can persist in the ground and inside plants for 20 years or more (probably more if its out of the sunlight).
Finland (I think), had the problem with reindeer many years ago, and they seemingly solved the problem by killing every reindeer and not reintroducing them for about 20 years. The only way to really get rid of it would be to kill every animal that the prions can reproduce in, and not reintroduce them for 30 years.
It takes a long time for the disease to show up, and some people could possibly be affected by it.
