Quoting The Diplomat:
For the first time, North Korea has confirmed a positive COVID-19 case within the country. The state-run Korean Central News Agency reported on May 12 that a “specimen from persons with fever” in Pyongyang had come back positive for the Omicron BA.2 variant, a particularly contagious strain of the virus. The phrasing of the announcement makes it unclear how many people are infected. KCNA called the development a “most serious emergency case of the state.”
