South Korea reported two-thousand 80 cases of COVID-19 on Wednesday.
The daily tally jumped by more than 580 cases from the day before,… which saw low numbers as fewer tests were done over the weekend.
All but 23 were locally transmitted cases with 80-percent coming from the capital region.
804 cases were reported in Seoul alone, and this is the highest figure ever witnessed in the city.
Authorities said 60-percent of Wednesday's cases were from people in their 20s to 40s.
Infections might be concentrated in the capital region right now, but authorities are concerned that they could spread nationwide with the upcoming Chuseok holiday.
"We strongly ask that people only visit hometowns if their parents are fully vaccinated, and that they keep to small groups and that those who aren't vaccinated take PCR tests.
Researchers also confirmed that it is crucial to ventilate rooms frequently and reduce gatherings as much as possible,… as these measures are proven to reduce the risk of infection.
More than 92-percent of the adults who contracted the virus over the past two weeks were either unvaccinated or had not been fully vaccinated.
There are also growing concerns over increasing numbers of Delta variant cases, as it accounted for 99.5-percent of all newly confirmed mutant cases over the past week.
So far, South Korea has reported a total of 47-hundred breakthrough infections,.. with eight in ten found to be linked to variant cases.
