They're still talking about reinfection. If that's the case, we are pretty screwed. Might just as well let natural selection run its course. I haven't looked at the evidence for that, but I was digging into the evidence for asymptomatic transmission.
The headlines say "studies" suggest, but they don't say the claim is based on case studies, which are barely more than anecdotal evidence. The one study (of which there were only two done according to the article) I read was pretty weak. The suspected carrier for a family cluster actually tested negative until everyone else started showing symptoms. They tested her again and she tested positive, but never developed symptoms. She was reportedly the only tie to the Wuhan area for that cluster.
Considering the source of the study, I'm skeptical. I'd like to see a better study done, and more clear numbers and explanations of how the transmission is supposed to occur.
