Abstract:
ObjectiveTo analyze the epidemiological characteristics and clinical symptoms of severe fever with thrombocytopenia syndrome (SFTS) cases in Xianju County, Zhejiang Province from 2017 to 2024, and to provide a scientific basis for prevention and control measures to reduce the incidence and mortality. MethodsSFTS cases reported in Xianju County from 2017 to 2024 were collected from the China Information System for Disease Prevention and Control. Case-related data were obtained through epidemiological investigations and medical record reviews. Data were organized and analyzed using WPS 2019 and SPSS 22.0, spatial maps were generated with ArcGIS 10.2, and multivariate logistic regression analyses were employed to explore the factors associated with mortality in SFTS cases. ResultsFrom 2017 to 2024, a total of 36 SFTS cases were reported in Xianju County, with an incidence rate of 1.15/100 000 and a case fatality rate of 27.78% (10/36). The majority of cases occurred in individuals aged 60 years old and above (55.56%, 20/36), with farmers being the most affected occupational group (86.11%, 31/36). The highest number of reported cases occurred in June and July. The local tick density was relatively high (1.25 ticks per host, 340/271). Multivariate logistic regression analyses indicated that thrombocytopenia was a related factor for patient mortality. ConclusionXianju County is an area with high incidence and case fatality rate of SFTS. It is essential to strengthen public awareness campaigns, emphasizing personal protection during outdoor activities to reduce infections and lower the incidence rate. In addition, comprehensive control measures such as environmental cleanup and pesticide application should be taken to reduce tick density. Local medical institutions should enhance professional training to improve diagnostic and report sensitivity for SFTS. Early symptomatic treatment should be prioritized for elderly patients and severe thrombocytopenia cases to reduce the case fatality rate.
