It's also easier to leave Italy and spread the disease because it doesn't have a DMZ in the North and lots of migrant workers and other EU nationals, free to leave at any time. Some have fled the lockdown using ferries through Croatia or Greece and then on to their home countries. When the North was quarantined, many Italians irresponsibly fled to the South, prompting the authorities to issue a country wide lockdown. Good luck trying to escape by ferry from Korea to Japan, Russia or China in the middle of a pandemic. North Korea is out of the question. Also Koreans are likely to obey the rules imposed during a healty emergency crisis (they also has a MERS epidemic in 2015), while Italians are more likely dismiss them as nonsense.
