Covid has already been proven to be a contributor as well: https://onlinelibrary.wiley.com/doi/10.1111/apa.16966

Imagine someone was stopping a police car with a gun and robbed them. Would he get just two years? And he would not abuse any given power or authority.

It’s not that surprising. “Only” about 0.2 % - 2 % get infected per week (depending on where you are), so there got to be some people who don’t know anyone who got it recently.

A few countries still have somewhat precise numbers. UK has the ZOE health study, which found over 1 million people currently being infected out of roughly 50 million (from memory; I don’t know how many people live in UK). Germany has the SentiSurv study, indicating incidences approaching 1000 again. While the latter is only a survey in a few major cities, it allows calculation of a dark figure when put in relation to officially registered cases, which can then be applied to all regions that have the same criteria for when to test.

Overall, not great that millions will miss a chance to get the upcoming vaccine that would provide very decent protection against the most common strains.
