SEOUL, May 8 (Yonhap) -- South Korea's health authorities are raising their guard against an increase in new virus cases, as the country reported yet another cluster infection Friday after easing social distancing.

The country detected 12 more cases of the new coronavirus Thursday, most of which came from overseas, bringing the nation's total infections to 10,822, according to the Korea Centers for Disease Control and Prevention (KCDC). The tally marked new daily cases of more than 10 for the first time in five days.

But health authorities said an additional 13 cases were reported Friday, marking yet another cluster infection.

All of Friday's new infections were linked to a virus patient who visited three clubs in Seoul's popular multicultural neighborhood of Itaewon on Saturday, just days before the country shifted toward 'everyday life quarantine.'
