The daily COVID-19 caseload in South Korea has surpassed 5-thousand for the first time.
The country on Wednesday reported an all-time high of 5,123 new cases.
This is a steep hike from the latest peak, which stood at around 4,100 last Wednesday.
Critical cases also hit new highs, with 723 critically ill patients reported.
An expert said that if South Korea keeps current measures in place, there could be 10-thousand cases a day by the end of January.
Health authorities in response to the latest surge have said that they'll look into imposing extra measures.
"The government will discuss extra prevention measures on the size of private gatherings in the capital area, limiting unvaccinated guests in cafes, and expanding vaccine passes, and will announce our conclusion sometime this week."
Meanwhile, South Korea has found its first suspected cases of Omicron.
Health authorities said Tuesday that a couple that had visited Nigeria tested positive for COVID-19 and officials are checking if they have the Omicron strain.
Both Canada and Hong Kong have also seen Omicron infections in travelers from Nigeria.
Health authorities confirmed the couple transmitted the virus to their teenage child and one of their acquaintances,.. so currently there are four people in South Korea suspected of carrying the Omicron strain.
The test results that tell if they have the Omicron strain are expected on Wednesday night, sometime around 9 PM.
Concerns are mounting following news of a confirmed Omicron case passing through South Korea.
A Namibian diplomat who was confirmed as being infected with Omicron in Japan, had a stopover at Incheon International Airport.
Health authorities are scrambling to investigate whether the virus has been transmitted locally.
