I've got a side theory. Keep in mind that shedding doesn't necessarily equate to infectious. If true it could only be a problem if you're near someone continuously. We're that the case, if we managed to put Trump back in and get hold of the reigns, it's a legitimate public health threat. These people would be responsible for their actions and would have to go out of their way to avoid the healthy part of the population and frankly they would have to be legally segregated until some reversal treatment is developed and proven.
