SEOUL, South Korea — South Korea’s new coronavirus daily tally has remained in two digits for a third straight day as authorities called for public vigilance during one of the country’s biggest holidays.

The Korea Disease Control and Prevention Agency said Saturday that the 75 virus cases added in the past 24 hours took the country’s total to 24,027 with 420 deaths.

South Korea’s caseload has recently displayed a downward trajectory following a spike in new infections between early August and mid-September. Stringent social distancing rules were credited with slowing the outbreak.

But worries about a rebound in new cases have grown again as South Korea is on the traditional autumn “Chuseok” holidays this week that would certainly increase public mobility.
