You were talking about NY, not South Korea,
The thread is about NY.
gas_dr was pointing out that the case mortality rate is only 0.5 times there and decreasing. 0.5% is still 5 times worse than the flu, but better than the 1$-3% many have been expecting.
I used S.Korea to point out that the rate has risen over time in S.Korea not decreased.
But NYC is using Chloroquine some, so maybe their rate will go down. Lets hope so.
