the fever or not. Studies show that Jeju Province is recorded as the region showing the highest incidence of severe fever with thrombocytopenia syndrome (SFTS) in South Korea. Just like the scarlet fever, the goal of this study was to determine the epidemiological and clinical characteristics of SFTS patients in Jeju Province. The data that was collected on this situation were obtained by the Integrated Diseases and Health Control System of the Korea Centers for Disease Control and Prevention (KCDCIS). 55 residents of Jeju were selected to test the criteria at KCDCIS and confirm the cases of SFTS with a residence listed in Jeju Province at the time of diagnosis, between July 16, 2014, and November 30, 2018. Results show that of the 55 confirmed cases of SFTS, the case fatality rate was 10.9% (95% confidence interval [CI], 4.1 to 22.2). The most common symptoms of the SFTS were severe fever, myalgia, and diarrhea. There have been fatality rates of 83.6% (95% Cl, 71.2 to 92.2), 45.5% (95% Cl, 32.0 to 59.5), and 40.0% (95% CI, 27.0 to 54.1). This particular study from 2014 to 2018, has been proven to have a lower case fatality rate and a lower incidence of severe fever, myalgia, and confusion than that of the cases nationwide of 2013–2015.
