Seoul, February 01, 2021, SPA -- South Korea has confirmed seven more cases of contagious variants of the new coronavirus, bringing the total caseload to 34, according to health authorities on Monday. The Korea Disease Control and Prevention Agency (KDCA) said the seven people were confirmed to have been infected with three kinds of variants that are known to be more transmissible over the past week. Of them, four variants were from Britain, followed by one from South Africa and two from Brazil, the KDCA said, according to Yonhap News Agency. The authorities have said they remain vigilant against the possibility that highly transmissible new variants could spark another uptick in virus cases. South Korea has extended the ban on passenger flights arriving from Britain, which has been in place since Dec. 23, until Feb. 11 to block the new virus variant that was first identified in Britain. The KDCA has conducted further tests, known as next-generation sequencing, on arrivals from Britain and South Africa. The method provides an effective way to identify coronavirus strains and other pathogens without prior knowledge of the organisms. Also, all foreign entrants must present papers showing negative PCR tests taken within 72 hours of their departure for South Korea. The country added 305 more COVID-19 cases on Monday, the smallest number in over two months, to stay in the 300s for the second straight day, according to the KDCA. --SPA 12:02 LOCAL TIME 09:02 GMT 0003 www.spa.gov.sa/w1496600
