SEOUL, Nov. 14 (Yonhap) -- South Korea's new coronavirus cases exceeded 200 for the first time in 73 days Saturday amid lingering cluster infections across the nation, with health authorities considering raising the social distancing scheme by a notch in the five-tier system.
The country added 205 more COVID-19 cases, including 166 local infections, raising the total caseload to 28,338, according to the Korea Disease Control and Prevention Agency (KDCA).
The number of new infections stayed in triple digits for the seventh consecutive day. The daily new cases reached 191 on Friday and 143 on Thursday.
It marked the first time for the daily figure to surpass 200 since 267 cases added on Sept. 2.
The KDCA reported four additional deaths, raising the total at 492. The fatality rate came to 1.74 percent.
Health authorities attributed the sharp growth to chains of cluster infections from private gatherings and public facilities, which made it more complicated for them to identify the transmission routes.
South Korea saw its number of daily new infections peaked at 909 in late February, after a minor church sect in Daegu reported major cluster infections.
The country faced another wave of pandemic in August, with the figure reaching 441 on Aug. 27 due to cases traced to another church in northern Seoul, coupled with an anti-government demonstration.
With signs of a possible slowdown, however, South Korea has kept the Level 1 social distancing scheme under a new five-tier system nationwide since earlier this month, although some cities and provincial governments upped their virus infection preventive measures.
Asan and Cheonan, both located in central South Chungcheong Province, adopted tougher measures last week. Wonju in Gangwon Province and Gwangyang and Suncheon in South Jeolla Province also raised their social distancing schemes to Level 1.5 this week.
Yeosu, located 455 kilometers south of Seoul, is also among the regions that enhanced their guidelines.
Under Level 1, people are required to follow basic guidelines, such as wearing masks, and gatherings of over 500 people are not recommended.
People are still allowed to carry on with most of their daily routines under Level 1.5, but gatherings of 100 or more people will be regulated, though not completely banned.
In line with efforts to curb the spread of the virus, South Korea started slapping fines of up to 100,000 won (US$90) on people who fail to wear masks in public places. Operators of those facilities and rally organizers will be fined up to 3 million won if they fail to ensure that users or participants stick to the requirement.
Among the locally transmitted cases, the capital city of Seoul accounted for 63 cases, and Gyeonggi Province that surrounds Seoul reported 46. The greater Seoul area houses around half of the nation's population.
Gangwon Province added 18 more infections, followed by South Jeolla Province with 13. South Chungcheon Province added 11 new cases.
As of Saturday noon, a sauna in western Seoul reported eight more patients, raising the total to nine. A hospital in the area also reported nine patients.
A nursing home in northern Seoul added nine more patients, raising the tally to 10.
In eastern Seoul, another nursing home added six more cases, with a total of 59 cases being traced to the facility.
A bank in Suncheon, 415 kilometers south of Seoul, added two new patients. A total of 10 patients have been reported there.
"As small-sized, sporadic group infections are rising outside the Seoul metropolitan area, there's a possibility that the country will raise the level of social distancing in some areas, should the current trend continue," a health official said during a regular briefing.
Health authorities said the average daily new cases of COVID-19 came to 122.4 over the past week.
President Moon Jae-in expressed concerns about spikes in new cases.
"Although the current situation is within a manageable level for our medical system, it is worrisome that it may spread further," Moon said in a Facebook post.
Moon called for citizens to strictly follow mask guidelines, especially as the annual college entrance exam is only 20 days ahead.
The country added 39 imported cases.
Among the imported cases, the United States accounted for 10 cases, followed by Russia with six and Poland with five.
There were also cases from the Philippines, Bangladesh, Myanmar and Japan.
South Korean nationals accounted for 55 percent of imported cases.
The number of seriously or critically ill patients came to 54, up four from Friday.
The number of people released from quarantine after making full recoveries came to 25,636, up 99 from the previous day. This indicates 90.4 percent of the patients reported here being cured.
South Korea has carried out 2,777,289 COVID-19 tests, including 15,878 from Friday.
Over the past two weeks, around 13.4 percent of the additional cases had unknown infection routes. Nearly 35 percent of the newly added cases were traced to cluster infections.
Health authorities, meanwhile, said its studies on 1,301 COVID-19 cases showed that the S and V strains of the new coronavirus were dominant through April, but mostly the GH strain has since been detected from a series of cluster infections.
Two cases were also infected with the GV strain, which has recently been categorized by the World Health Organization, they added.
