South Korea on Thursday reported 14-thousand 5-hundred 18 new infections.
This is roughly 8-thousand cases higher than the same time last week, and double the amount reported on Monday.
South Korea's total number of cases has now topped 7-hundred 77-thousand.
But the number of critically ill patients is down by 35 to 3-hundred 50.
Thursday's record-high comes from the spread of the Omicron variant, which is milder but at least twice as transmissible as the Delta variant.
To efficiently use limited medical and virus prevention resources against the surge authorities have decided to only use PCR tests on people over 60, those at high-risk or those who had close contact with confirmed cases.
Everyone else will have to use a rapid antigen test kit at testing sites instead.
This measure will take effect nationwide from February 3rd.
The Ministry of Education is also considering using rapid antigen test kits at schools.
Currently, schools only provide PCR tests to students.
Under-18s make up more than 30 percent of all cases and the Education Ministry is pushing through its plans for in-person classes from March.
Already 1-thousand 1-hundred 89 schools in the nation have opened up which is 10 percent of all the schools in the country.
The Ministry of Education will release a new set of guidelines for Omicron after the holidays.
