South Korea has reported 73 new cases of the coronavirus, its fifth straight day of below 100, although officials expressed concern that could rise because of increased travel during a five-day holiday period that ended on Sunday.

The figures released by the Korea Disease Control and Prevention Agency brought the national caseload to 24,164, including 422 deaths.

According to AP, 51 of the new cases were reported from the greater capital area, where health workers have scrambled to stem transmissions tied to various places, including churches, hospitals, schools, restaurants and workplaces.

The newest cluster of infections in the region is an army unit in Pocheon, north of capital Seoul, where more than 30 troops have so far tested positive.
