According to the website worldometers.info, South Korea has 8,236 total cases at the time of this post, 10:12 p.m on 3/15. That comes out to .016 of 1% of their population.
And according to the principle of Farr's Law, all epidemics and pandemics follow a predictable and symmetrical bell curve. The increase in the number of cases in South Korea peaked on March 3, 13 days after the first recorded case. The number of active cases peaked on March 11, 21 days after the first recorded case. Assuming the first person in South Korea got the disease 14 days prior to March 3, that means, at least according to Farr's Law, South Korea will be virus free 35 days after March 11, or April 15, with well under 1% of their population being afflicted.
Cole put up a link featuring Stanford professor and Nobel Laureate Michael Levitt, who said China will have no cases by the end of March. This seems to bolster that South Korea will be done by April 15 as the timelines are similar.
As I asked earlier, what am I missing here?
