And maybe even millions of tests performed worldwide, it’s hard to believe that the experts don’t have some sort of idea of the actual prevalence in the population. It only takes reserving a few thousand tests to test randomly to at least get a ballpark idea of the ratio of asymptomatic to symptomatic carriers, after which you can extrapolate so that you aren’t off by a factor 100 or 1000.

The closest thing I have seen to this is in South Korea, where more than 50% of cases were in people under 50 years old, and iirc something like 80% were asymptomatic.

I would imagine the experts have much more data available than the public does so it’s hard to be overly critical of them, but I still have the urge to do so.
