The South Korean government has reintroduced stricter anti-virus measures to tackle the latest surge.
Starting Monday, for four weeks, the social gathering capacity in the capital region will be limited to six people - down from 10, and eight in other regions, reduced from 12.
Vaccine passes will also now be required in restaurants and cafes.
From February, the use of passes will be further expanded to teenagers.
To prevent additional Omicron variant cases in the country, for the next 2 weeks, all travelers arriving in South Korea have to quarantine for ten days.
