2.1 SFTS patients
We performed a retrospective study on eligible patients with SFTS from May 2013 to April 2022. During the study period, 84 patients were confirmed to be positive for partial small (S) and large (L) segments of SFTSV RNA using real-time PCR.[16]
Of these patients, 65 confirmed patients were analysed in the present study (Supplemental table 1 ). The study was approved by the Institutional Review Board (IRB) at the Jeju National University Hospital (IRB file no. 2021-03-012) and the study design and baseline characteristics of SFTS patients are available in theSupplemental Data 1 .
