Abstract

After reopening the border, North Korea was experiencing community transmission of SARS-CoV-2 and implemented a nationwide lockdown. We estimated that the mean transmissibility declined to <1 within 5 days after the lockdown and that the lockdown was associated with a moderate decrease in transmissibility by 11% (95% confidence interval, 6–17%).

Keywords: North Korea; SARS-CoV-2; lockdown; outbreak; transmissibility.
