Your covid cases
do not represent the entire population of a country where there could be 80/90% of it real positives, but without being sick. So it would, on the contrary, decrease the real lethality, outside of hospitals. We also see that they are very happy to find a few cases "younger" than the old (funny wording moreover, vague as much as possible) the 8 million vaccinated current being cases that have become positive by the vaccine.
This would mean that in France there were not 4.7 million covid cases but 470000. It considerably increases the case fatality rate.
Your theory is a little anxiety-provoking.

This is the difference between apparent lethality (CFR) and actual lethality (IFR) already explained time and time again. I think everyone's been ok with this for a long time.
Insofar as these are only
theoretical models and not based on the real situation where many aspects escape theorists
These methods allowed researchers to calculate, as of March 2020, the case fatality rate linked to the COVID-19 epidemic for the first time in a country other than China, France. They calculated a case fatality rate of 0,5% based on hospital data and a rate of 0,8% integrating data from nursing homes.So based on elderly people hospitalized and in nursing homes, that is to say a tiny part of the population and I talked about
the total population of the country.
