South Korea on Wednesday reported 1-thousand 7-hundred 25 new COVID-19 cases, up by more than 5-hundred from the day before.
Non-capital regions reported almost 6-hundred-30 cases, the highest number since the fourth wave broke out.
Daegu saw 113 cases as of Wednesday afternoon., surpassing the hundred mark for the first time in 17 months.
With cases surging outside the capital, health authorities are on alert with more people traveling across the nation during the summer vacation period.
"The amount of people moving in the metropolitan area increased by 0.8% from the previous week, so there is no significant change. However, it is serious outside the capital as the number of people moving increased by 6.4%. These areas have been seeing an increase for the third week in a row."
Authorities are also voicing concerns over the highly transmissble Delta variant.
In the last week of July, the Delta variant was detected in 62-percent of all cases.
This is a huge jump compared to the last week of June when it only accounted for 10-percent of cases.
The Delta Plus variant has also been detected in two cases in the country so far.
In light of this, the government on Friday will be announcing any changes to social distancing restrictions which will be effective from next week.
Prime Minister Kim Boo-kyum on Wednesday said the government will monitor the situation closely for the next two days before deciding on whether to readjust the current restriction levels.
The government added there is no plan to change the ban on gatherings of more than two people after 6 pm under the highest level four.
Currently, the greater Seoul area is under the strictest level, while most areas outside the capital are under level 3.
