…Do the math?
572,000÷26,300=0.04597 or 4.60%.
So if 4.60% of active cases die, then as a first-order approximation would this be correct?:
418,000 (still-active cases worldwide)*0.04597=19,219 more deaths worldwide after 27 Mar?
94,091 (still-active US cases)*0.04597=4,326 more US deaths after 27 Mar?
Or will the number of deaths be even larger before the curves flatten out?
A more sophisticated model currently predicts 81,114 US deaths by 01 Aug (range 38,242–162,106).
