SEOUL, July 1 (Yonhap) -- The number of new virus cases in South Korea bounced back Wednesday as cluster infections continued to increase in areas beyond the Seoul metropolitan area amid a sustained rise in imported cases.
The country added 51 cases, including 36 local infections, raising the total caseload to 12,850, according to the Korea Centers for Disease Control and Prevention (KCDC).
The tally marked a rise from 43 new cases of COVID-19 reported Tuesday and 42 cases on Monday.
Densely populated Seoul and the surrounding area accounted for most of the locally transmitted cases last month, but the virus outbreaks have been constantly reported in other parts of the country.
Of local infections, 20 cases were reported in the greater Seoul area. Twelve cases were identified in the southwestern city of Gwangju, marking the first time that virus cases hit double-digit figures since the first outbreak in the city in February. Three cases were reported in the central city of Daejeon.
In yet another worrisome sign, two elementary students in Daejeon tested positive Tuesday, the first spread of the virus at a school in the country.
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.
School reopening, completed in early June, is a key feature of the eased social distancing rules.
Cluster infections traced to small religious gatherings have emerged as the main cause for the latest spike in local infections.
Cases traced to a major church in Seoul's southwestern ward of Gwanak reached 31 as of noon Tuesday, up three cases from the previous day. Those linked to a Buddhist temple in Gwangju rose by two to 14.
The country's health authorities remain jittery over a potential new wave of virus outbreaks in the summer amid sustained rises in local infections and cases coming in from overseas.
The country, meanwhile, reported 15 additional imported cases, raising the total of such cases to 1,598.
It marked the sixth straight day that imported cases rose by a double-digit number.
A rise in cases coming in from overseas put further strains on health authorities' virus fights, with some calling for the need to implement restrictive entry measures selectively. On Tuesday alone, 10 cases were traced to arrivals from Kazakhstan.
South Korea, meanwhile, reported no additional deaths, bringing the death toll to 282. The fatality rate was 2.19 percent.
The total number of people released from quarantine after full recoveries stood at 11,613, up 76 from the previous day.
The country has carried out 1,285,231 tests since Jan. 3.
