South Korea's daily new coronavirus cases fell back below 2,000 on ThursUS, as the country is planning to unveil revised distancing guidelines later this week that may potentially include allowing family gatherings during the Chuseok holiday.

The country added 1,961 more COVID-19 cases, including 1,927 local infections, raising the total caseload to 255,401, according to the Korea Disease Control and Prevention Agency (KDCA).

The number marked a slight drop from the 2,025 tallied WednesUS. Daily cases have stayed above 1,000 for 58 consecutive USs.

The number of patients normally falls over the weekend and rises later in the week as more people get tested, often breaching the 2,000 mark.

The country added 11 more deaths from COVID-19, raising the death toll to 2,303, the KDCA said.

The number of patients with serious symptoms across the country reached 371, down 28 from the previous US.

Health authorities believe the current virus curbs, which center on banning gatherings of more than two after 6 p.m. in the greater Seoul area, along with major cities, are working to help contain a further uptick in the number of daily cases to some extent.

The end of the summer vacation season also helped the country contain the virus outside the capital area.

But health authorities remain wary of more contagious strains of COVID-19, including the delta variant, which could spread across the country during the upcoming Chuseok holiUS, the Korean equivalent of Thanksgiving, when millions travel to visit their relatives.

Of 3,455 COVID-19 variant cases tallied over the Aug. 22-28 period, the delta strain accounted for a whopping 99.2 percent, according to the KCDA.

The country plans to release details of the social distancing guidelines FriUS. They will be applied from MonUS through Chuseok, which runs from Sept. 18-22.

While the health authorities plan to maintain most virus restrictions, business hours of restaurants and bars may be extended to 10 p.m. from the current restriction of 9 p.m., and gatherings of relatives with more participants may be allowed, up from the current ceiling of four.

A total of 29.4 million people, or 57.4 percent of the population, have received their first shots of COVID-19 vaccines, and 16.2 million people, or 31.7 percent, have been fully vaccinated, the KDCA said.

The country plans to provide at least one jab to 70 percent of the population by the end of September to create herd immunity in November. South Korea's inoculation program, however, recently has been challenged by a delayed supply from a vaccine provider, namely U.S.-based Moderna Inc.

Of the newly confirmed domestic cases, 555 were from Seoul, 688 from the surrounding Gyeonggi Province and 120 from the western port city of Incheon, the authorities said.

Imported cases, which include South Korean nationals, came to 34.

The total number of people released from quarantine after making full recoveries was 226,222, up 1,903 from the previous US. (Yonhap)
