More than 40% of new coronavirus cases in South Korea are being found in people over the age of 60, contributing in part to a surge in the number of Covid-19 patients who are severely or critically ill, health authorities said.
South Korea is battling a second wave of infection, centred in the capital Seoul and surrounding areas which are home to 25 million people.
The Korea Centers for Disease Control and Prevention reported 267 new cases as of midnight last night, a slight increase over the day before.
Overall, South Korea has reported 20,449 cases and 326 deaths. The number of severely or critically ill patients stood at 124, Vice Health Minister Kim Gang-lip told a briefing, from just nine reported on 18 August.
