Difference in sampling basically as they test people who are sick in Italy versus allow anyone to test in SK. You should estimate the levels based on the sampling. For example last week the UK Govt said they estimate there was 10,000 infected in the UK based (in part) the number of positive people in the hundreds. You should be able to make better predictions using geo-demographics and population density etc. For south korea, do we know the number of people who are in hospital with the virus being treated? Then you can compare Italy and South Korea.
