A couple living in Incheon are suspected to be been confirmed with the Omicron variant of COVID-19.
They visited Nigeria from November 14th to 23rd and tested positive upon arrival in South Korea on November 25th.
The couple both received their second Moderna jabs in October.
Genome analysis is underway with the results expected to come out on the evening of Wednesday December 1st.
Two others who picked them up from the airport were also confirmed with the virus, and are suspected to have the new variant as well.
Health authorities are currently tracing the people who were on the same flight.
Not only that, but authorities are putting their fullest efforts in to checking whether or not the new Omicron variant has been detected elsewhere in South Korea by going through the genome analysis of the imported cases.
Starting from Friday November 26th, some 60 cases are being analyzed with results to come out before the end of the week.
As concerns over Omicron are rising, South Korea banned entry of foreigners from eight African countries and could add more to the list depending on the spread.
Following that, President Moon Jae-in on Tuesday urged the tightening of the country's entry procedures effective immediately.
Japan on Tuesday detected its first Omicron case after a diplomat from Namibia tested positive upon arrival on November 28th.
Genetic analysis has confirmed that it is Omicron.
