South Korea’s capital Seoul on Monday mandated the wearing of face masks in both indoor and outdoor public places for the first time, as the country battles a surge in coronavirus cases centred in the densely populated city region.

In May, Seoul’s government had ordered that face masks be worn on public transport and taxis, but the latest spike in cases has health officials worried that the country may need to impose its highest level of social distancing.

The Korea Centres for Disease Control and Prevention reported 266 new cases as of midnight on Sunday, a drop from the 397 new infections reported a day earlier but a continuation of more than a week of triple-digit daily increases.

In Seoul, people will now be required to wear face masks in public indoor places, as well as crowded outdoor areas, except while eating or drinking, the city announced on Sunday.
