摘要

摘要:
目的了解山东省沂源县发热伴血小板减少综合征（severe fever with thrombocytopenia syndrom， SFTS）的流行病学特征，为制订科学防控措施提供依据。
方法采用描述性流行病学方法对2014—2019年沂源县SFTS疫情数据进行分析。
结果2014—2019年沂源县共报告SFTS病例130例，报告死亡4例，年平均报告发病率为3.79/10万，6年间的报告发病率整体呈上升趋势（ $χ_{T r e n d}^{2}$ =9.06， P=0.003）。SFTS报告病死率为3.08%。5~8月为发病高峰（88.46%），发病年龄集中在≥50岁人群（81.54%），职业以农民为主（94.62%），发病到确诊中位时间为5 d。
结论SFTS在沂源县分布范围广，病例分布有明显季节性，发病人群主要是农村中老年人，应加强对农村中老年高危人群防控工作。

Abstract:
ObjectiveTo understand the epidemiological characteristics of severe fever with thrombocytopenia syndrome （SFTS） in Yiyuan County， and provide scientific evidence for prevention and control strategies.
MethodsDescriptive epidemiological methods were used to analyze the incidence of SFTS in Yiyuan County during 2014—2019.
ResultsA total of 130 SFTS cases were documented in Yiyuan County during 2014—2019， of which four were death cases. The annual incidence was determined to be 3.79/10⁵ and the mortality was 3.08%， showing an upward trend in the incidence （ $χ_{T r e n d}^{2}$ =9.06， P=0.003）. Majority of the cases occurred between May and August （88.46%）， were more than 50 years old （81.54%）， and farmers （94.62%）. The median duration of time from onset to diagnosis was five days.
ConclusionSFTS was widely distributed in Yiyuan County with seasonal pattern. Middle aged and elderly farmers were mainly susceptible. It warrants strengthening prevention and control of SFTS and health education in elderly.
