The country's daily COVID-19 caseload has surpassed 7-thousand for the first time.
On Wednesday, the daily tally reached 7-thousand 1-hundred 75.
The number of critically ill patients also went up by 66 to reach 840 going above the 8-hundred mark for the first time since the pandemic began.
Amid record-high figures, there have also reportedly been long lines of people waiting to get tested.
The number of ICU beds left for critically ill patients is quickly running low.
More than 84 percent of all beds in the greater capital area were being used, and nearly 70 percent of beds in other regions were occupied.
Health authorities said the number of critically ill patients has outpaced their expectations.
They said bringing this number down within the next two weeks is critical.
"Our medical capacity can withstand up to 10-thousand people getting infected. But, we would have to make major medical adjustments if we see this number go higher."
President Moon Jae-in also reportedly viewed the situation as severe.
In a briefing on Wednesday, the Blue House spokesperson Park Kyung-mee shared how the President had asked authorities to use all available resources and commit their fullest efforts to keeping the pandemic under control.
Authorities stressed they would make treating patients at home an easier and more convenient option to make sure they have enough hospital beds for critically ill patients.
The mandatory quarantine period for family members or those living with virus patients opting for self-treatment at home will be reduced from 10 days to 7 days as long as they're fully vaccinated.
They also said they would give out financial aid based on the number of people in each household.
Oral COVID-19 medication will also be given to those in the high-risk category being treated at home, from early next year.
