SEOUL, July 6 (Yonhap) -- South Korea saw its daily new virus cases slightly fall Monday, but a steady rise in both locally transmitted infections and imported cases continued to put a strain on the country's virus fight.
The country added 48 cases, including 24 local infections, raising the total caseload to 13,139, according to the Korea Centers for Disease Control and Prevention (KCDC).
The tally marked a slight decrease from 61 new cases of COVID-19 reported Sunday, as well as 63 new cases on both Friday and Saturday.
Of local infections, seven cases were reported in the southwestern city of Gwangju, followed by six each in Gyeonggi Province surrounding Seoul and the western port city of Incheon. Three cases were reported in Seoul, the KCDC said.
As of Sunday, 80 cases have been tied to Gwangneuk Temple in Gwangju, up 13 from a day earlier. The figure includes cases from a church, also in the city, as the two clusters were found to have connections.
The government of South Jeolla Province, which surrounds Gwangju, said earlier it will raise the region's social distancing to level 2 from the current level 1, which is equivalent to "distancing in daily life."
The upgrade calls for tougher virus prevention measures, including banning gatherings of 50 or more people indoors or 100 or more people outdoors, and making it mandatory to wear masks when using public transportation.
South Korea has been harried by rises in sporadic cluster infections in the greater Seoul area since it relaxed strict social distancing on May 6 on the flattened virus curve.
The country, meanwhile, reported 24 additional imported cases, raising the total of such cases to 1,690. Of the new cases, 15 were detected at quarantine checkpoints.
South Korea has posted a double-digit number of imported cases for 11 consecutive days.
As to a theory that the COVID-19 virus is airborne, local health authorities said more studies should be reviewed.
Earlier in the day, hundreds of scientists said there is evidence showing smaller particles of the virus can infect people in the air, contradicting reports that the coronavirus disease spreads from person to person through small droplets from the nose or mouth.
"More studies should be reviewed for further proof on whether the virus spread is airborne," Vice Health Minister Kim Ganglip said in a briefing.
South Korea, meanwhile, reported one more death, bringing the death toll to 284. The fatality rate was 2.16 percent.
The total number of people released from quarantine after full recoveries stood at 11,848, up 16 from the previous day.
The country has carried out 1,331,796 tests since Jan. 3.
