This has already infected humans in some places. Deer hunters ate deer meat from infected animals and got what appeared to be Creutzfeld-Jakob disease. https://www.neurology.org/doi/10.1212/WNL.0000000000204407
The plus side if there is one is that not too many people eat deer meat.
A large percentage of people in my area eat venison regularly for at least part of the year. We already have controls on place for CWD so I have to hope that would catch any similar cases before someone eats the meat.
