SEOUL, South Korea – Authorities in the North Korean capital Pyongyang have ordered a five-day lockdown due to rising cases of an unspecified respiratory illness, the Russian Embassy and Seoul-based NK News reported on Wednesday. Seoul, citing a government notice.

The notice, shared by the embassy on its Facebook page, said that «a special anti-epidemic period has been established» and called on foreign delegations to keep employees inside. The order also called for people to take their temperatures four times a day and report the results to a hospital by phone.

The notice did not mention covid-19, though it did cite an «increase in winter cases of recurring flu and other respiratory illnesses.»

The blockades were first reported by South Korea’s NK News, which monitors secretive North Korea.

North Korea acknowledged its first outbreak of covid-19 last year, but had declared victory over the virus in August.

It has never confirmed how many people have contracted covid, apparently because it lacks the means for widespread testing.
