Napkin math time.
Population of the USA (+10mil illegals)
~= 340,000,000 ppl
Virus expected to infect about 60% of population over the course of the next year (x0.6)
=204,000,000 sick
One in four cases requires hospital care for roughly 3 weeks (x0.25)
=51,000,000 deathly ill
Number of licensed hospital beds in the USA (+ 100,000 to assume emergency measures)
~=1,000,000 beds
Adjust for time in bed per patient, complete with extremely optimistic idea that cases will be spread out evenly over the course of the year and med staff doesn't collapse (x52/3)
=17,333,333 people able to get care
Difference of 51m and 17.3m = 33,666,666 dead / 204,000,000 sick = 16.5% fatality rate.
Better hope someone figures out a cure. Barring that, get sick first, before the healthcare system comes crashing down.
