Given a large enough sample size, you're also going to get people who recover, test negative due to a false negative, then get influenza two weeks later, then test positive due to dead SARS-COV-2 RNA.
And various other edge case permutations like that.
I always suspected those were mostly due to false negatives from PCR tests. Probably only a tiny minority of people had not enough immune response for them to become reinfected.
