The figures in China are declining as expected. This means that the biggest difficulties in China will probably be of an economic nature and that in some areas people are experiencing or already have problems of various kinds (monetary, ...) due to the quarantine.
Numbers in SK seem to peak or maybe even go down, which is great news again.
You have to remember that R0 for COVID-19 is probably around 3, which means that theoretically every infected person infects three new people. Without successful containment, numbers in China or SK should double or even triple daily and within a few days you would be in the four-digit range of newly infected people. Ultimately, we are now actually in a situation in which each country can prevent the spread of COVID-19 with appropriate measures, which should be rather strict. If one or two countries fail to do so, a snowball effect may occur, which is certainly the greatest risk at present.
The sporadic reports of new infected people all over the world were completely to be expected (even the WHO said so). It would be an alarm signal if the numbers in a country suddenly tripled daily. Currently this is not happening anywhere, which is good news.
Instead of a major global pandemic with 500,000 or even several million infected people, it looks more like the economy will end up being the biggest problem for many when it is all over.
