There's been talk that previous coronaviruses don't cause immunity and there already seems to have been cases with this one where a person got it twice. Does anyone have insight?
- baq 7y agoWe don’t know but it is expected that immunity lasts for at least 6 months. Time will tell, this thing hasn’t been out long enough.
- chrisweekly 7y agocitation please
- baq 7y agoNo reported reinfections and we’re 4-5 months in.
- DavidSJ 7y agoThere have only been a handful of such reports with COVID-19, and they’re probably false test results.
- vharuck 7y agoHave people actually been infected twice? I know people have been hospitalized for COVID-19, assessed as recovered, and released only to test positive later. But have they proven that's from a second infection, rather than a premature release or residual virus bits?
- hirundo 7y agoI've read that coronavirus is a near relation to the common cold virus. How significant is it that catching a cold doesn't seem to give you immunity from catching another?
- na85 7y agoThat's because the common cold mutates very quickly, so by the time you catch another cold it's effectively a new virus.
- hirundo 7y agoIs coronavirus different in that respect?
- AstralStorm 7y agoIf we can use data related to Human Coronavirus strains (HCov), which are responsible for many colds, then not that much different. Of course, SARS-CoV-2 could be different. For SARS-CoV and MERS-CoV, there was no data on this.
- DiogenesKynikos 7y agoThe "common cold" is a catch-all phrase for many different viruses, which are not all closely related to one another. The coronaviruses that circulate in humans (other than SARS-CoV-2) are common colds. My understanding is that they do not mutate quickly, but that for whatever reason, one infection does not confer lasting, complete immunity to later reinfection (though later infections may be less severe).
- rimliu 7y agoYou can get colds from different viruses.

- randomsearch 7y agoNot an expert, but this sounds like social media hysteria rather than science.
- coretx 7y agoThe second infection is likely about the virus reaching the lungs while it did not make it there previously. Meanwhile, asymptomatic carriers etc. are still being researched.
- coffeefirst 7y agoI have yet to hear this from a credible source. It appears to be a self perpetuating rumor. All it would take us a few people who catch Coronavirus in addition to one of the many things floating around with similar symptoms to think they caught it twice. It’s just too easy.

- shlant 7y ago> "there already seems to have been cases with this one where a person got it twice" Just so people know: this has not been confirmed and has been an unsubstantiated rumor for a while. It is pretty unlikely this will happen considering what we know about how things like this function on a physiological level. It is much more likely due to the changes is testing (mostly where on the body samples were taken), confusion about symptoms or false negatives.
