South Korea is not yet considering a blanket ban on foreign arrivals because of the new Omicron coronavirus variant.
Kim Joo-shim, head of international immigration at the Korea Disease Control and Prevention Agency, said in a briefing Monday that they will continue to monitor the spread of the variant, which was first identified in South Africa.
The origins of Omicron and whether its is more dangerous than other variants have yet to be confirmed scientifically.
On Sunday, South Korea implemented a ban on all foreign arrivals from eight southern African countries -- South Africa, Botswana, Zimbabwe, Namibia, Lesotho, Eswatini, Mozambique and Malawi.
No cases of the variant have been found in recent arrivals from these nations, according to the KDCA.
The agency said more countries could be put on the travel ban list, depending on the number of Omicron cases that are reported domestically.
