If we believe the population of infected to double ever 3 day

and the current number of infected is 50,000 in 45 days(a

month and a half) the number of infected becomes terrifying.

50000 * 2^15 = 1,638,400,000. Three days after that 3 billion.

6 days after that, everybody on earth.

Now, the above calculation is wrong.

The R0 will shrink as there are fewer people to infect.

So the growth will grow at some kind of logistic rate and it will take longer then 2 months to progress to the final conclusion.
