Starting Monday, people will only be required to wear a mask outdoors when participating in gatherings of more than 50 people or attending sports and cultural events with potentially large crowds, health authorities said in a briefing Friday. The mask mandate for indoors and public transport will also remain in place.

Health workers had diagnosed a daily average of around 63,000 new cases in the past seven days, including 50,568 in the latest 24 hours — a drop-off from mid-March when the country reported hundreds of thousands of infections each day at the height of an omicron-driven surge. As hospitalizations and deaths slow, less than 30% of the country's 2,800 intensive care units designated for COVID-19 patients are occupied. South Korea had already removed much of its pandemic restrictions earlier this month, including a 10-person limit on private social gatherings, a midnight curfew at restaurants, coffee shops, and bars, and a ban on food consumption at movie theaters, concert halls, and indoor sports venues.

Jeong Eun-kyeong, the Korea Disease Control and Prevention Agency commissioner, said the weeks-long decline in infections, even with the easing of social distancing, suggests that the country's outbreak is stabilizing. She said health authorities concluded it was safe to relax the mask mandate because the risk of transmissions is much lower outdoors. Other countries didn't see a meaningful increase in infections after easing similar restrictions. Jeong recommended that people still wear masks outdoors if they have symptoms like coughs or fever or are in crowded spaces like theme parks where it's hard for them to maintain at least a meter (3-foot) distance from others.

However, the office of President-elect Yoon Suk Yeol, who took office on May 10, raised concern that the move to ease the mask mandate could be premature. Hong Kyung-hee, the spokesperson of Yoon's presidential transition committee, said the committee had recommended the government monitor virus trends for at least another month before deciding whether to relax the mask mandate.
