There are a few reports of people in China being released having overcome the virus being readmitted and then dying. Possible that they were just released too early, but also possible that they recaught the disease as it mutated. Unclear to me which from the twitter chatter I've seen on it, but I'm hopeful it's the former and not the later.I wish that were true. You only need 60 or 70% infected to get enough herd immunity to drastically slow it down.
