RE-INFECTION TRACKER—now 11: There has now been 11 documented cases of #SARSCoV2 infection. @BNONews has been tracking such clinical reinfections of #COVID19. By BNO unofficial tabulation, there are now 11, 4 of which suffered more severe 2nd infection. https://abs.twimg.com/emoji/v2/... draggable="false" alt="🧵" title="Thread" aria-label="Emoji: Thread"> https://bnonews.com/index.php/2020/08/covid-19-reinfection-tracker/">https://bnonews.com/index.php...

2) The most recent reinfection was reported yesterday in a 42 year old military healthcare worker in a Virginia military hospital. 2nd infection was worse than the first, 51 days after initial. But recovered. https://twitter.com/drericding/status/1308724605234880514">https://twitter.com/drericdin...

3) The first ever officially documented reinfection case was from Hong Kong on August 24th. In that case, the patient had a milder 2nd #COVID19 illness. They always verify reinfection with a second genome https://abs.twimg.com/emoji/v2/... draggable="false" alt="🧬" title="DNA" aria-label="Emoji: DNA"> sequence and compare with the first infection gene https://abs.twimg.com/emoji/v2/... draggable="false" alt="🧬" title="DNA" aria-label="Emoji: DNA"> sequence. https://twitter.com/drericding/status/1297854438221197313">https://twitter.com/drericdin...

4) The second major documented reinfection was from Reno Nevada on August 28th. But this time, the second infection was more severe requiring hospitalization. https://twitter.com/drericding/status/1299362114373648385">https://twitter.com/drericdin...

5) as pointed out before, reinfections are rare (we think), but clearly do happen— out of millions of cases, you’re bound to find some. But @VincentRK says it should be rare enough that immunocompromised people should be okay.

6) that said ”In order to provide herd immunity, a potent vaccine is needed to induce immunity that prevents both reinfection & disease” according to experts. This has implications also for herd immunity too. https://twitter.com/drericding/status/1297987970453184512">https://twitter.com/drericdin...

7) That said, expert admit it is hard to “confirm” a reinfection per se. Because it requires having full virus samples from both infections to run full genome https://abs.twimg.com/emoji/v2/... draggable="false" alt="🧬" title="DNA" aria-label="Emoji: DNA"> sequences on both. That’s harder to come by, more expensive to run, and more rare since it’s usually needs researchers
