Nearly one year after North Korea closed its borders to protect itself from COVID-19, the country once again claims to have zero confirmed cases of the virus as of Jan. 14.

According to a new report from the World Health Organization, surveillance for the virus is still ongoing in the DPRK, with 15 laboratories conducting COVID-19 tests throughout the country. The latest report does not include total testing numbers or the number of people in quarantine, but a previous WHO update stated that North Korea had tested a total of 26,244 samples from 13,259 people as of Dec. 31, 2020.
