South Korea has reported 49 new domestic coronavirus cases, the smallest number of locally transmitted cases in 44 days in a sign that tighter social distancing rules are paying off.

Health officials reiterated calls on people to refrain from visiting their hometowns and meeting with relatives during the Chuseok holiday, worrying that the holiday, which runs from September 30 to October 2, may lead to another spike, Reuters reported.

On Friday, South Korea said it would further tighten restrictions during the Chuseok holiday weeks when people traditionally reunite with families in the densely populated Seoul metropolitan area.

The rules include the closure of nightclubs and bars in the Seoul area and keeping at least a 1-metre distance between tables at restaurants and cafes with more than 20 seats.
