South Korea's daily new virus cases fell back to the 400s on Monday as fewer people took new virus tests over the weekend with concerns over another round of the pandemic still worrisome amid a low vaccine supply.
The country reported 488 more COVID-19 cases, including 465 local infections, raising the total caseload to 123,728, the Korea Disease Control and Prevention Agency (KDCA) said.
The country added one more death, raising the death toll to 1,834.
The daily caseload has been in the 600s for the past six days. Due to worries over a potential rise in new cases amid warm weather, health authorities extend social distancing rules and a ban on private gatherings of five or more people for three more weeks until May 23.
The greater Seoul area, home to more than half of the country's 52 million people, is under Level 2 social distancing, the third highest in the five-tier scheme, with non-capital regions under Level 1.5.
The authorities will adopt new distancing rules in 22 counties and cities in South Jeolla Province, which have posted an average of 2.3 new cases a day over the past week, starting Monday.
The revamped social distancing system will go into effect across the country in July if daily virus cases remain under 1,000 by end-June.
Under the revamped Level 1 distancing, private gatherings of six or fewer people are allowed and up to 300 people can gather for events.
A total of 3,396,864 people have received at least their first shots of COVID-19 vaccines since the country started its vaccination program on Feb. 26.
AstraZeneca's vaccine has been given to 1.83 million people, while 1.57 million have received that of Pfizer.
A total of 16,627 cases of side effects after vaccinations have been reported, up 121 from a day earlier, but 98.1 percent were mild symptoms, including muscle pain and fever.
The KDCA said 82 deaths after vaccinations have been reported, up three from the previous day. They said the exact causes of the deaths remain unknown as they could not determine causality.
The country aims to vaccinate 12 million people by the end of June in a bid to achieve herd immunity by November.
On Sunday, acting Prime Minister Hong Nam-ki said about 5 million more doses will be shipped in phases by the end of June and the government has been consulting with the U.S. drugmaker to speed up the delivery date.
Of the locally transmitted cases, Seoul reported 123 new cases, and Gyeonggi Province that surrounds the capital city identified 129 new patients.
South Gyeongsang Province registered 44 additional cases, and Busan and Ulsan, major cities in the southeastern region, reported 16 and 21 new cases, respectively, becoming a new hot spot for infections.
There were 23 new imported cases, up two from Sunday.
The number of patients with serious symptoms across the country reached 164, down six compared with the previous day.
The total number of people released from quarantine after making full recoveries was 113,356, up 491 from a day earlier. (Yonhap)
