Can you get coronavirus twice? Doctors are unsure, even as anecdotal reports mount.

They disagree over whether the evidence is convincing and what the implications might be for vaccines.

Iran appears to be the only country making a concerted effort to assess #SARS2 #Reinfection. They are suggesting it is happening. They seem to be unclear on whether it is a product of mutation or more general immune response decline.

I get that only the really bad anecdotes of potential #Reinfection of #SARSCoV2 might get reported. Again, when will we study #Reinfections in earnest and, if it is a phenomena we have to deal with in the shorter term, what are the population level risks?

Thus, for persons recovered from SARS-CoV-2 infection, a positive PCR during the 90 days after illness onset more likely represents persistent shedding of viral RNA than reinfection. So >90 days could mean reinfection? Another tone change?
