>But where is South Korea going with its strategy

drawing the infections out so that the hospital system can stay stable and thus minimizing the amount of people who die from the disease. Not to mention that there will likely be a vaccine within 12-24 months and medication approved within the next few months.

Mind you this is in addition to South Korea having ~13 hospital beds per 1000 people, compared to ~8 in Germany and 2.5(!) in the UK. This strategy in the UK to let the virus eat through the population is insane.

Wuhan had the great majority of cases in the entire world. The other provinces of China are more analogous to individual European countries. They locked down for a few weeks and have already come back up.

The long term strategies for Korea and China are the same: carefully identify new cases as they come in from outside, find their contacts, and isolate them as soon as possible. Temporarily lock down small regions on an individual basis if necessary. They've already been doing that with some new cases coming in from Italy.

> Wuhan had the great majority of cases in the entire world.

That was true a day or two ago, but that's a bit outdated now: Wuhan at most has had a bare majority of total cases in the world now, and probably a minority. In any event, it'll be a minority in a few hours.

What I don't understand is... Won't this just flare up again in another city the size of Wuhan at some point?

Yes, but hopefully they'll identify the flare-up much more quickly and be able to contain it with more targeted measures, before things get to the level they reached in Wuhan in late January.

Once you remove community spread, you only need to deal with international travel, which can be dealt with much more cost-effectively.

Long term they are working on a vaccine and anti-virals.
