The fourth wave of the pandemic is not showing any signs of slowing as the daily new coronavirus cases bounced back above 1,5-hundred mark.
The country reported 1,5-hundred-9 cases on Tuesday, up 91 from the previous day's figure.
Of them, one,4-hundred-70 were local infections with 65 percent of them from the capital area.
39 cases were from overseas.
Health authorities say there could be a further surge in infections due to the highly contagious Delta variant.
The number of Delta variant infections in the last seven days in South Korea amounted to 3,33, taking up some 99 percent of infections from the four major variants.
Authorities said the Delta variant spreads much more than the original COVID-19 virus.
"Currently the Delta variant emits up to 300 times more virus on the very first day of the infection than the non-variant strain that was prevalent during the first wave of pandemic."
In order to curb the spread of the Delta variant, health authorities urge people to get vaccinated.
Inoculation for those aged 18 to 49 starts on Friday.
The authorities said some people who have reserved their shots for after the Chuseok holiday will be able to move up their appointments as more doses of Moderna vaccines are supplied.
The government said they will stabilize the 4th wave and that students going back to school to take in-person classes is needed for society.
Meanwhile, another 1.5-9 million doses of the Pfizer vaccine purchased directly from the company, will arrive at Incheon International Airport on Wednesday.
