I got pericarditis bad enough that I thought it was going to kill me but not bad enough to show up in any test. Thankfully the cardiologist accepted my description of what I felt and prescribed me colchicine which worked. I guess it would be called subclinical pericarditis and it would be good to have some stats on how often that happens.

I suspect many people commit the grave sin of mixing data sources to derive percentages, which seems almost impossible not to do in this case. I also strongly suspect that rates of infection (the denominator in question) were inflated to some extent during the pandemic as insurers and hmo were incentivized to detect covid even when it may not have been the primary reason for presenting. There were also disincentives or at least a lack of incentive to detect teratogenic effects of the lipid nanoparticle based preventative, and unfortunately likely personal biases as the preventative was highly politicized. But I’m not thinking about it much deeper than that, so you may be right.
