No, the point is, you probably don’t. Most anecdotal “reinfections” are from people who think they were infected, but never had it confirmed.

These stories are also typically second- or third-hand, and resemble whatever story was most recently in the news: “my ‘friend’ had a bad cold in March 2020, then got tested in July and had Covid. He was reinfected!” Stories that are heavy on hearsay, but light on details.

When we actually go and look for reinfections using rigorous standards, we find that they’re incredibly rare. It’s highly unlikely that there’s a huge wave of reinfections that we’re simply not seeing after hundreds of millions of infections and months of effort to find them.

Not sure what you mean by "confirmed", but this particular case had positive PCR results for both the first infection and the subsequent re-infection after 4 months.
