The government on Friday announced that people visiting restaurants, cinemas and other public spaces will have to show vaccine passes.

South Korea has also confirmed three additional Omicron cases, bringing the total to nine after a fully vaccinated couple tested positive for the variant after travelling from Nigeria last week. To fend off the new variant, authorities on Friday announced a 10-day mandatory quarantine requirement for all inbound travellers for two weeks, halting exemptions given earlier to fully vaccinated people. read more South Korea has been battling the worst wave of infections since July, when the daily cases stood below 2,000 until the government switched to "living with COVID-19".

The country, which has fully inoculated 91.7% of its adult population, has so far reported a total of 467,907 COVID-19 infections, with 3,809 deaths since the start of the pandemic.
