A case of coronavirus reinfection exhibits the complexities of the pandemic

The scary factor lastly occurred: somebody caught the coronavirus twice and obtained sicker the second time round. A 25-year-old man in Nevada obtained COVID-19 in March, obtained higher in April, and obtained sick once more in Might. He had worse signs on the second bout, unhealthy sufficient that he needed to be hospitalized.

Three different instances of confirmed reinfection have been additionally reported this week: one in Hong Kong (the primary documented case) and two in Europe. These don’t essentially make me any more worried about our vaccine prospects, although, they usually don’t imply the pandemic will go on without end. Now we have 4 documented instances of reinfection. However that’s out of the 24 million instances of this illness to this point, and uncommon shit occurs. Most specialists anticipated that we’d see at the least a number of.

For months, there have been occasional, anecdotal stories of individuals testing optimistic for COVID-19 twice. None of these have been confirmed to be reinfections. For many of these individuals, the second check in all probability picked up residual, lifeless virus that was nonetheless floating round in individuals’s noses and throats after their first an infection.

In these reinfection instances, although, researchers truly analyzed the virus from the primary time the individuals obtained sick and in contrast it to the virus from the second time they obtained sick. In every case, the 2 viruses had barely totally different genetic sequences, displaying that the second optimistic checks weren’t simply leftover virus.

Right here’s the opposite vital factor: within the Hong Kong case, the second an infection induced no signs in any respect. Which means his immune system in all probability acknowledged the virus from the primary an infection and stored it in verify. We don’t know why that didn’t occur for the person in Nevada. He wasn’t examined for antibodies the primary time he obtained sick, so it’s potential that he simply didn’t make any. That’s the extra encouraging choice. The opposite chance is that he had antibodies, however they made the an infection worse (it occurs with different viruses, like dengue).

Case research solely reply one query: are you able to catch COVID-19 twice? However that’s about all they do. Largely, they elevate questions reasonably than reply them. How widespread is reinfection? How infectious are individuals in the event that they get sick a second time? Are individuals who don’t generate many antibodies the primary time they contract the virus the one individuals who can catch it once more?
