Analysis on epidemiological features of severe fever with thrombocytopenia syndrome,Shandong province,2013-2015

目的了解山东省2013~2015年发热伴血小板减少综合征(SFTS)的流行病学特征,为更好地预防和控制SFTS提供科学依据。方法采用描述流行病学方法对山东省SFTS病例资料进行分析,应用Excel 2007进行资料整理,SPSS13.0进行数据统计分析。结果 2013年以来,山东省SFTS报告病例数、发病率总体呈上升趋势(P<0.01)。3年间除菏泽市尚无SFTS病例报告外,其余各市均有病例报告,病例主要集中于胶东半岛和鲁中地区,占报告病例总数的65.93%(842/1277)。发病呈现较明显的季节性,5~8月为发病高峰,75.56%(965/1277)。病例以40~79岁居多,占88.25%(1127/1277)。农民为主,占84.10%(1074/1277)。山东省的三级医疗机构为主要的报告单位,占47.14%(602/1277)。结论山东省SFTS病例主要发生在丘陵山区的中老年人,呈现明显的季节分布特征,不同地区发病存在差异。

Objective To understand the epidemiological characteristics of severe fever with thrombocytopenia syndrome （SFTS） in Shandong province,2013-2015,so as to provide scientific basis for its control and prevention. Methods The descriptive epidemiological method was used to analyze the data of SFTS cases. Microsoft Office Excel 2007 and SPSS 13.0 software were used for statistical analysis. Results There was an increasing trend for the numbers and the inci- dence rates of SFTS cases since 2013（ P 〈0.01）. SFTS cases were reported in all the other cities except Heze city during 2013-2015. Cases mainly occurred in the Jiaodong Peninsula and the central regions of Shandong province, accounting for 65.93% （842/1 277） of the total reported. SFTS cases showed a significant seasonal distribution each year with peaks during May-August,accounting for 75.56% （965/1 277）;40-79 year-old age group was the highest,accounting for 88.25 （1 127/1 277）. Most cases were farmers,accounting for 84.10%（1 074/1 277）. Tertiary medical institutions were the main reporting units in Shandong province,accounting for 47.14%（602/1 277）.
