@spudmato. I agree, I think at this point even scientists and doctors do not know the whole spectrum of this virus because it happens so quickly and spreads even faster. We don't know why some elderly patients recovered and yet young patients die from it. I can only guess, and I stress the word guess, that immunity has alot to do with it. Until there's a vaccine, or a drug that we are positive would work, we have to continue to be vigilant not to put ourselves and everyone around us in danger of exposure.
