摘　　要：目的分析2011—2022年安徽省发热伴血小板减少综合征(SFTS)的流行病学特征,为SFTS的防控工作提供科学依据。方法通过中国疾病预防控制信息系统获取SFTS数据资料,采用描述性流行病学方法、Joinpoint回归模型等分析其三间分布特征。结果2011—2022年安徽省累计报告SFTS病例4298例,年均发病率为0.58/10万,年均死亡率为0.02/10万,SFTS发病率及死亡率整体呈上升趋势[平均年度变化百分比(AAPC)=19.08%,P<0.001;AAPC=15.30%,P<0.01]。病例发病时间集中在4—10月,占病例总数的94.97%。男、女性发病率分别为0.55/10万、0.62/10万,女性发病率高于男性(χ^(2)=13.872,P<0.001)。病例发病年龄集中在60~75岁(46.21%),职业以农民为主(85.06%)。病例报告地区数由2011年的6个地市23个县(区)增加至2022年的12个地市62个县(区),报告发病率居前3位的县(区)为滁州市南谯区(9.40/10万)、六安市金寨县(6.67/10万)和滁州市明光市(4.50/10万);报告死亡率居前3位的县(区)为马鞍山市含山县(0.44/10万)、滁州市全椒县(0.17/10万)、合肥市肥东县(0.12/10万)。2011—2022年共报告23起SFTS突发公共卫生事件,其中聚集性疫情20起,以家庭聚集为主(75.00%)。结论安徽省SFTS发病率呈上升态势,病例分布呈扩散趋势,具有明显时空聚集性,应在流行季节对山区/丘陵地区中老年人重点开展宣传教育并加强监测管理工作力度。Objective To analyze the epidemiological characteristics of severe fever with thrombocytopenia syndrome(SFTS)in Anhui province from 2011 to 2022,and provide evidence for the prevention and control of SFTS.Methods The incidence data of SFTS in Anhui during this period were obtained from China Information System for Disease Control and Prevention for a descriptive epidemiological analysis,and Joinpoint regression models were used to analyze the distribution of the disease.Results From 2011 to 2022,a total of 4298 SFTS cases were reported in Anhui.The average annual incidence rate was 0.58/100000 and the average annual mortality rate was 0.02/100000 with overall increasing trends[average annual percent change(AAPC)=19.08%,P<0.001;AAPC=15.30%,P<0.01].The cases mainly occurred during April-October,accounting for 94.97%of the annual total.The incidence rate was 0.55/100000 in men and 0.62/100000 in women,with a higher incidence rate in women than in men(χ^(2)=13.872,P<0.001).The cases were mainly distributed in age group 60-75 years(46.21%).Most cases were farmers(85.06%).SFTS cases were reported in 23 counties(district)of 6 prefectures(municipality)in 2011,but in 62 counties of 12 prefectures(municipality)in 2022.The top 3 counties reporting high incidence rate were Nanqiao of Chuzhou(9.40/100000),Jinzhai of Liu'an(6.67/100000)and Mingguang of Chuzhou(4.50/100000).The top 3 counties reporting high mortality rate were Hanshan of Ma'anshan(0.44/100000),Quanjiao of Chuzhou(0.17/100000)and Feidong of Hefei(0.12/100000).Twenty-three SFTS public health emergencies were reported,of which 20 had case clustering,mainly in families(75.00%).Conclusion The incidence of SFTS showed an increasing trend in Anhui with a wide distribution of the cases and obvious spatial and temporal case clustering.In the disease epidemic season,it is necessary to strengthen the health education about SFTS in middle-aged and elderly people in local mountainous/hilly areas and improve SFTS surveillance.
