SEOUL, South Korea (AP) — North Korea’s recent admission of its first domestic COVID-19 cases has surprised many outsiders and prompted speculation about how bad the outbreak is and whether it could cause a major humanitarian crisis in a country where public medical infrastructure is terrible. Some experts say North Korea may face one of the world’s worst per-capita fatality and infection rates if it doesn’t get outside aid shipments soon. Others argue that North Korea may just want to use the outbreak to tighten public vigilance against the virus and boost its control of its people.
