Take a look at the “case” curves and the “death” curves at the Worldometer site:
https://www.worldometers.info/coronavirus/#countries
They look almost identical.
So much for the case data not meaning anything...despite its obvious flaws it turns out to be a proxy for the death rate...it predicts/shows the trend.
More importantly, it is a fair proxy for actual infections. It is probably off by a consistent factor, but since the known death rate is in the 1-2% rate with good care and higher with an overwhelmed health care system it is clear that it is not off by _that_ much, perhaps a factor of two or three at most.
That shows the lie of the “lots of people have mild cases and are now immune” FluBro meme that has infested parts of academe as well as the political world.
The numbers say that this drama is still just beginning—in the US substantially less than 1% would test positive even if everyone were tested.
If folks don’t like the real world, that is not the fault of the real world.
