SEOUL - South Korea has reported yet another record daily high in Covid-19 cases, with new clusters found all over the country, including a popular ski resort, as the authorities expand testing capability to track down asymptomatic cases in the third and most severe wave of infections. A total of 1,078 new cases were added on Wednesday (Dec 16), beating Sunday's record of 1,030 and raising the tally to 45,442. Health authorities admitted that the current Level 2.5 social distancing, in place since Dec 7 in Seoul and greater Seoul where most of the clusters are, have failed to flatten the infection curve, and that the weekly average of 832.6 cases a day now calls for the highest Level 3.
