SEOUL, Oct. 6 (Yonhap) -- South Korea's new coronavirus cases stayed below 100 for the sixth straight day Tuesday, but the country is bracing for a possible resurgence in new infections after a long holiday as a slew of clusters was reported.
The country added 75 more COVID-19 cases, including 66 local infections, raising the total caseload to 24,239, according to the Korea Disease Control and Prevention Agency (KDCA).
It marked a slight rise from 73 posted on Monday and 64 cases reported on Sunday.
After daily infections hit 133 on Wednesday last week, they have been in double-digit figures. The drop was in part attributed to fewer tests carried out over the five-day Chuseok holiday that ran through Sunday.
Health authorities had advised people to refrain from visiting their family members and relatives this year over the Korean equivalent of Thanksgiving.
They also allowed public transportation to sell only window seats in line with efforts to prevent the spread of the virus over Chuseok, when millions normally travel across the country.
Nevertheless, around 30 million people traveled across the nation over the holiday, down 3.1 percent from the previous year. The number of people traveling by trains and buses decreased 57 percent and 55 percent.
Health authorities are concerned that there could have been a number of asymptomatic patients who spread the virus during the Chuseok holiday.
Considering the incubation period, health authorities said there could be another wave of the pandemic soon despite the latest slowdown in the daily new cases.
As the country will enjoy another three-day break from Friday to Sunday to celebrate the Korean alphabet, South Korea earlier designated a special two-week period for toughened virus curbs until the end of the holiday.
The special ant-virus scheme centers on maintaining most of the Level 2 social distancing policy nationwide, under which indoor gatherings of more than 50 people are banned.
Facilities more prone to virus infections, such as clubs and bars, will stay shuttered until the deadline in the greater Seoul area, which houses around half of the nation's population. Those in other regions, however, were allowed to resume business starting Monday.
South Korea operates a three-tier social distancing system. The government has not yet issued the highest alert, which bans gatherings of 10 or more people, as it will come at a significant consequence in terms of the economy.
Over the past two weeks, 18.2 percent of newly added patients had unknown infection routes. Although the ratio is still worrisome for the authorities, it still marked a sharp drop from 28.1 percent posted in mid-September.
According to the latest data, 26.5 percent of cases were grouped as cluster infections as well.
The country's new virus cases had been in the triple digits for more than a month since Aug. 14, due mainly to cases tied to a church in northern Seoul and an anti-government rally. Daily infections soared to 441 on Aug. 27.
Of the newly identified local infections, 13 cases were reported in Seoul and 34 cases in Gyeonggi Province that surrounds the capital. Incheon, west of Seoul, reported four more cases.
The southern port city of Busan added three cases, and North Jeolla Province reported nine more patients.
A church in northern Seoul reported four patients as of noon Monday, after reporting its first confirmed case Saturday.
A military base in Pocheon, north of Seoul, reported 36 virus cases, sparking concerns over yet another major group infection. Health authorities are currently working to identify the infection route.
Imported cases came to nine. The Philippines and Britain accounted for two cases each. There were also infections from India, Syria, Ethiopia, the Czech Republic and the United States.
So far, South Korean nationals accounted for 60 percent of the imported infections.
South Korea added no additional deaths, keeping the death toll at 422.
The fatality rate came to 1.74 percent.
The number of patients in serious or critical condition came to 105, down two from the previous day.
The total number of people released from quarantine after making full recoveries stood at 22,083, up 197 from the previous day. Some 91 percent of the patients reported here have been cured.
South Korea has carried out 2,365,433 COVID-19 tests since Jan. 3, including 13,055 from the previous day. The number of daily tests fell below 10,000 over the holiday.
