CFR of 0.6% is a very optimistic figure. It is a naive calculation based on current # deaths / # infections.
1) But # infections were growing exponentially, we need to use numbers from the same cohort, which implies much lower # infections & higher CFR. Naive CFR will go up once infections grow more slowly. (It already is higher than 0.6%).
2) South Korean confirmed cases are much younger than their median age, mainly between 20-29 years old (perhaps because of where superspreading events happen—that church). This age group has a much lower fatality rate from Covid-19.
3) # hospital beds per capita in South Korea is second highest among OECD countries (1st is Japan) and ~4 times that of the US. They already have patients waiting for beds. Most countries will do much worse if they reach the same # infections per capita.
