Given that the US COVID-19 death rate "so far" is approximately 190 per million head of population, that's not bad going, at least on the surface. Of course the wider figure won't be purely for those of working age, but it would still help if they were able to provide a valid comparison.
A 190 per million mortality rate depends on continuing to prevent the majority of the population from getting it. No one knows what proportion of people have had it, maybe 5% as a wild guess? If so, and it spread across 100% of the population, and they all only got it exactly once, then the mortality rate would be 3.8 deaths per thousand.
