It's very hard to trust these low prevalance numbers when, for example, I know a few people who are close friends with people in medical fields who tested positive but they themselves didn't get tested but had mild symptoms. I myself had mild symptoms that I'm 99% sure is covid and didn't get tested.
Just because you and your friends weren't tested, doesn't mean the statistics are invalid. The link above was from random antibody testing and has a high confidence interval.
I've been sick twice during this time. Thought it had to be COVID, but two PCR tests and an antibody test all came back negative. Maybe the tests are flawed, sure, but it's far more likely I just had something else.
