> How long immunity lasts for following covid-19 infection is the biggest unknown. Comparison with other Coronaviridae suggests it may be relatively short-lived (i.e. months).
Anyone have sources for this?
I've been skeptical of the rumors about reinfection, because they seem to be based on tests coming back positive after recovery, but the tests are rt-PCR based, and your body will be shedding leftover bits of RNA as it flushes out viral remnants long after recovery, so this seems expected.
As far as I'm aware, immunity to most viruses is long-lasting or permanent, with the obvious exception being if the virus mutates enough to look different to your immune system. Is this assumption wildly off?
