We can never know how many people Covid killed in America, because the rubric in the US is to count as a Covid "death" any death where the deceased tested positive for covid. In that group might be someone who would have not died had they not had Covid, but it also includes many people who would have died regardless of Covid positivity.

It is also to count as a Covid hospitalization, anyone hospitalized who tests positive for Covid in the hospital.

In both cases, all we can say is that somewhere between none and all of them are actually in that condition because of Covid.
