摘要
目的分析江苏省发热伴血小板减少综合征(severe fever with thrombocytopenia syndrome,SFTS)聚集性疫情病例的流行病学特点,为防控工作提供科学依据。方法搜索聚集性疫情相关病例,开展病例及其共同暴露者、密切接触者的流行病学调查。描述病例的基本情况和发病经过,分析感染来源和传播途径。使用Fisher确切概率法和独立样本t检验来比较首发病例和续发病例之间的差异。结果2018—2024年江苏省共报告9起聚集性疫情,涉及SFTS病例32例,死亡12例。聚集性疫情有7起发生在农村社区,2起发生在医疗机构。聚集性疫情发生的主要原因为直接接触确诊病例。结论近年来江苏省SFTS发生多起聚集性疫情,高发地区应开展针对性健康宣传,增强个人防护意识;医疗机构需规范确诊病例管理,并告知家属防控知识,同时应该加强医护人员的培训,做好院内感染控制。
Objective This study analyzed the epidemiological characteristics of the clustered cases of severe fever with thrombocytopenia syndrome(SFTS)in Jiangsu province,so as to provide a scientific basis for prevention and control efforts.Methods In this study we searched for cases related to clustered outbreaks and conducted epidemiological investigations of the cases,their co-exposed individuals,and close contacts.The basic information of the cases and their disease progression were collected and documented.The source of infection and transmission routes were analyzed.Fisher’s exact probability test and independent samples t-test were used to compare the differences between index and secondary cases.Results From 2018 and 2024,a total of nine cluster outbreaks were reported in Jiangsu province,involving 32 cases of SFTS with 12 fatalities.Seven clustered outbreaks occurred in rural communities,while two occurred in medical institutions.The primary cause of these outbreaks was direct contact with confirmed cases.Conclusions In recent years,Jiangsu province has experienced multiple clustered outbreaks of SFTS.Targeted health education should be implemented in high-risk areas to increase awareness of personal protective measures.Medical institutions should standardize the management of confirmed cases,educate patients′families about prevention and control measures,and strengthen training for healthcare workers to ensure effective infection control within hospitals.
