Coronavirus Poses Major Threat to North Korea's Fragile Health System Eunjung Cho North Korea is among a handful of countries in the world claiming to be free of COVID-19. The country is also among the most ill-prepared for a coronavirus outbreak. "I do think the North Korean government is very well aware of how weak their health care system is," said Katharina Zellweger, director of KorAid, a Hong-Kong-based non-governmental organization. "They're afraid they can't cope with an outbreak, and this is why all these measures were put into place so early." Zellweger, who has been providing humanitarian aid to North Korea since 1995, spoke during a conference call Monday hosted by the Wilson Center. She explained that North Korea sealed off its border with China at the end of January, quarantined foreigners and enforced domestic travel restrictions. Crumbling medical system North Korea ranked 193th out of 195 countries surveyed, followed by Somalia and Equatorial Guinea, in the Global Health Index, in a study released last October by Johns Hopkins Center for Health Security. .
