SEOUL, South Korea — South Korean officials are moving to limit travel and gatherings during next week’s Lunar New Year’s holidays by allowing train operators to sell only window seats and passenger vessels to operate at half capacity.

The Health Ministry announced the steps Wednesday while repeating a plea for people to stay home amid a steady rise in coronavirus infections.

Officials also plan to strengthen sanitization and install more thermal cameras at train stations, bus terminals and airports. Travelers will be required to be masked at all times and will be prohibited from eating food at highway rest areas.

Officials have also extended a clampdown on private social gatherings of five or more people, which they enforce by fining restaurants and other businesses if they accept large groups.
