Re-infection is very rare, so the chance that it happened to two people in the same household is extremely rare. Are you certain you were infected with covid both times?

Not certain, but the second time we had a positive PCR test to confirm. The first time, there were no tests in NYC but close contacts had it and we had the same exact symptoms (which are not similar no any other flu/disease we have had).

People in the same household have high chances of infecting each other.

Please read that comment again, it's about RE-infection

I know it is, my point is that two spouses getting re-infected isn't two independent things.

It's not like bringing your bomb onto a plane decreases the odds of an attack, because what are the odds of two bombs.

The devil is in the details here. If natural immunity wears off after 6-9 months (as some studies suggest), and one spouse got infected again after that period, then the odds of the other one of getting re-infected too are pretty high.

Wow really? Do you have positive test results that document the sequence of events?

If so you should probably email these researchers or something. Bet they would be interested

There is already a decent understanding of documented reinfections. The first such cases came out a year ago, e.g.: https://en.yna.co.kr/view/AEN20200406006700320 , or https://www.jpost.com/health-science/israeli-doctor-reinfect... By the end of last summer there were clear documented cases with secondary infection from a different viral strain than the original one, e.g: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3681489 The original publication (and the reply that I cite that raises some concerns, but leaves the main argument in place) estimated that the protection from a past infection is about 83%, so significantly smaller than that from the 2-dose mRNA vaccines. https://www.bmj.com/content/372/bmj.n124/rr-0

While I agree reinfections are likely to exist in small numbers, the tests we're using are often not great so it's hard to say whether those were covid or something else.

This year I've been heavily sick several times (and the flu almost never caused me all this pain before in my life) and it was never covid.

If one of the test returned a false positive I would have been convinced it was covid. If I actually got covid again I would have believed I was one of the rare reinfections.

PCR tests are more likely to give you a false negative than a false positive.

The second time we had a positive PCR test to confirm. The first time, there were no tests in NYC but people I worked with had it confirmed and we had the same exact symptoms (which are not similar no any other flu/disease we have had).

You really shouldn't be saying this on public forums without proof. You have no proof that the first infection wasn't the flu or a bad cold. The odds of reinfection are very small, and the odds of both of you getting reinfected is vanishingly so. Without proof this is potentially fear mongering.
