South Korea officials are imposing more social distancing rules in the greater Seoul area starting Wednesday amid a new coronavirus outbreak.
Under the stiffer rules, only two-thirds of students will be allowed in school classrooms, while clubs and karaoke bars will be required to ensure there is more distance between patrons.
The defence ministry held a meeting of senior commanders and notched up distancing for troops and officers for the next two weeks and cut travel and entertainment events, after more than two dozen cases have recently been linked to a military welfare support facility and an air force unit.
The tougher restrictions came as the daily case tally hovered above 200 for a fourth consecutive day, with a series of cluster outbreaks emerging from offices, medical facilities and small gatherings in Seoul and surrounding regions where around half of the country's 52 million population live.
"The heightened curbs would cause greater inconvenience in our daily lives ... but we all know from our experiences that there would be an even bigger crisis if we don't act now".
Chung noted an increase in R-naught, which represents the number of other people each patient is likely to infect and is now at 1.12, according to Yonhap.
Of the new cases, 193 were locally transmitted and 30 imported, according to the KDCA.
Of them, 202 were locally transmitted and 28 imported, and almost 68 per cent of the domestic infections came from the greater Seoul area, KDCA data showed.
The Korea Disease Control and Prevention Agency (KDCA) posted 223 cases as of Sunday midnight, marking the eighth straight day of triple-digit increases and the highest since early September. Authorities have warned previously that the transmission route for such clusters can be hard to trace.
South Korea has now reported a cumulative total of 28,998 confirmed cases of coronavirus, with 494 deaths.
