South Korea has extended level 2 social distancing for a week until September 27 and may tighten limits for the Chuseok holiday when people traditionally reunite with families.
Prime Minister Chung Sye-kyun said the level 2 restrictions - which limits indoor gatherings to below 50 and outdoor to less than 100 - need to be kept ahead of Chuseok as "cases with untraceable origins are steadily increasing and fewer tests being carried out on weekends means we should be on high alert".
Social distancing policies for the September 30-October 2 holiday will be announced in the coming days.
