The next 32 days will be the most intense.
The number of positive cases reported will double every two to three days.
Multiply these positive confirmed test cases by 20
to get “real number” of infections.

“Herd Immunity” starts when about forty percent of people have recovered and have immunity.

Forty percent of 330 million is 132 million.
Divide 132 million by 20 to get
6.6 million positive test cases.

USA at 0.2 million now.

6.4

Five doubles to get from 0.2 to 6.4
Two to four days for each doubling.

Big urban areas will get there faster.
More isolated rural areas will be considerably slower.

Total deaths will depend on finding a drug ( maybe Colchicine,maybe the statin drug Crestor)
to moderate the “Cytokine Storm” that is fatally damaging lungs.

If the recovered would donate plasma twice a week that has a high chance of working,
same for if we could make artificial antibodies quickly.
