South Korea reported 635 new cases of COVID-19 on Wednesday of which 613 were local transmissions.
Wednesdays are usually higher than other days as testing from weekdays starts to show and today's numbers are slightly down from recent Wednesdays over the past few weeks.
In addition, the R number, which shows the rate of transmission, has been slowly declining since four weeks ago.
"Recently, the spread has been declining, but the rate of decline is very slow and the threat of cases rising again still exists."
Adding to the threat is the recent spike in variant cases.
Nearly 25 percent of local transmissions were shown to be a variant case twice what the percentage of variants was last week.
They are known to be more transmissible, and vaccines are not as effective against variant cases.
On the other hand, the government is looking into adjusting the virus prevention measures from this July when most of the people over 60 would have received their first shot of the vaccine.
"We are doing our best with our goal of first consistently pulling new daily cases below 500. If these figures continue, we'll review distancing measures, including operating hour restrictions and the limit on the number of people at private gatherings."
More South Koreans landed at Incheon International Airport on Wednesday morning aboard a special flight arranged by Asiana Airlines which departed from New Delhi.
This is the fourth group this month and more than 700 Koreans have returned so far.
Of those who have returned, 16 have been confirmed to have the virus so far and one of them is known to have the new Indian variant.
