This is nonsense. You completely disregard that the entire world's medical community has become vastly better at treating infectious people. In the early days, when NE states, Spain, Italy, etc. were hit hard, people who had to go to the hospital died at alarming rates. Since then, we have learned that prone position, dexamethasone, supplemental (non-intubated) oxygen, convalescent plasma, etc. contribute to vastly lower death rates. Of course per capita death rates are high in the NE states. We had no effective treatments then.
