According to the Hawai Public Radio, South Korea appears to be a relative success story when it comes to dealing with COVID-19. On Friday, the number of the cases in the country passed 10,000. But even though South Korea has “flattened the curve” of the spread of the virus, authorities are still increasing their prevention measures.

Anyone who gets off an international flight landing in Seoul and who wants to stay in the city will need to get tested for the novel coronavirus. Right away — and even if they are not showing any symptoms.

Last Wednesday, the central government started mandatory quarantines for all arriving passengers to South Korea — and officials quickly demonstrated they are serious about the rules. At least eight foreign nationals from six countries have been deported after refusing to self-isolate for two weeks.
