摘　　要：目的了解2017—2022年浙江省东阳市发热伴血小板减少综合征(SFTS)的流行特征,为SFTS防控工作提供依据。方法通过中国疾病预防控制信息系统监测报告管理系统收集2017—2022年东阳市SFTS病例资料,描述性分析SFTS病例的流行特征及临床特征;采用年度变化百分比(APC)分析SFTS发病趋势。结果2017—2022年东阳市报告SFTS病例32例,发病率为0.63/10万;死亡8例,病死率为25.00%;2017—2022年发病率呈上升趋势(APC=40.697%,P<0.05)。SFTS病例男女性别比为0.78∶1;职业以农民为主,31例占96.88%;发病年龄以51~<70岁为主,20例占62.50%。SFTS发病高峰期为3—5月和7—8月,28例占87.50%。病例分布于全市18个乡镇(街道)中的11个,佐村镇病例数最多,9例占28.13%。血小板计数最低值为(41.46±5.19)×10^(9)/L,最低值范围为(3.00~67.00)×10^(9)/L。32例SFTS病例发病前2周均有山林、农田活动史;5例有明确的蜱叮咬史,占15.63%。结论2017—2022年东阳市SFTS发病率呈上升趋势,春夏季高发,农民为主要发病人群。应加强重点地区居民SFTS健康教育。Objective To investigate the epidemiological characteristics of severe fever with thrombocytopenia syndrome(SFTS)in Dongyang City,Zhejiang Province from 2017 to 2022,so as to provide insights into SFTS prevention and control.Methods Data pertaining to patients with SFTS in Dongyang City from 2017 to 2022 were collected from Notifiable Infectious Disease Reporting System of Chinese Disease Prevention and Control Information System.The epidemiological and clinical characteristics of patients with SFTS were descriptively analyzed,and the trends in incidence of SFTS was evaluated using annual percent change(APC).Results A total of 32 SFTS cases were reported in Dongyang City from 2017 to 2022,with mean annual incidence of 0.63/105,and 8 cases died,with a fatality rate of 25.00%.The incidence of SFTS appeared a tendency towards a rise from 2017 to 2022(APC=40.697%,P<0.05).The male to female ratio of SFTS cases was 0.78∶1,and farmer was the predominant occupation(31 cases,96.88%).SFTS predominantly occurred among individuals at ages of 51 to 69 years(20 cases,62.50%),and the incidence peaked during the period between March and May and between July and August(28 cases,87.50%).SFTS cases were reported in 11 out of the 18 townships(streets)in Dongyang City,with the highest number found in Zuocun Township(8 cases,28.13%),and had the lowest platelet count of(41.46±5.19)×10^(9) platelets/L,with the lowest count of(3.00 to 67.00)×10^(9) platelets/L.All the SFTS cases had a history of mountain forest and farmland activities 2 weeks prior to onset of the disease,and 5 cases(15.63%)had a history of tick bites.Conclusions The incidence of SFTS appeared a tendency towards a rise in Dongyang City from 2017 to 2022,and SFTS was highly prevalent in spring and summer,with high incidence among farmers.Intensified health education of SFTS is recommended among residents in high-incidence areas.
