The 1st #COVID19 case in the US was diagnosed Jan 21.
It has since taken 53 days to do ~20,000 tests.
That's how many South Korea does in 1 day now.

That broad testing in South Korea (now >270,000 tests) was mounted early along with social distancing, closing of schools, tracing contacts. Total cases now 8162, curve flattened to lowest number of cases (76) since Feb 22; 75 deaths (0.9%). 
The broad testing of people w/exposure, no symptoms, picked up on the key asymptomatic group, now understood to be a major driver of spread, especially among the young (unlike Italy/US testing)

A Table that summarizes key differences between these 3 countries for #COVID19 at end of day March 14 (3/15 in Korea)
Updated my table with 1st date of diagnosis, data sources
Note that the start (1st dx) dates for South Korea and the US were within 1 day.
The difference in preparation and response has led to very different outcomes and new case curves, even with the paucity of US testing and detection
