Abstract excerpt

BACKGROUND: From late March through April 2021, we experienced a cluster of patients with COVID-19, named "Cluster K", with rapid severe illness compared with those who were infected before. METHODS: Patients with COVID-19 who were enrolled in this study were divided into two groups: 66 patients from November 2020 to March 2021 (group A) and 37 patients whose infection links were traced from Cluster K (group B)....
