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 .
