2009—2018年河北省病毒性出血热流行态势分析

Epidemiological analysis of viral hemorrhagic fever in Hebei provinc,2009-2018

目的了解河北省病毒性出血热疫情的流行形势,为病毒性出血热的临床诊治和预防控制提供科学依据。方法收集整理2009—2018年河北省法定传染病疫情资料,筛选肾综合征出血热(HFRS)、登革热(DF)和发热伴血小板减少综合征(SFTS)病例的个案资料,基于描述性流行病学的分析方法开展回顾性研究。结果2009—2018年,河北省共报告病毒性出血热病例6105例,包括HFRS病例6050例,每年均有病例报道;DF病例54例,均为输入性病例;SFTS病例1例,为外省输入性病例。本地流行的HFRS有明显的地区和季节分布特征,病例主要集中于河北省东北部地区(82.55%),春季(3-5月)为流行高峰(占全年发病数的39.77%)。20~59岁年龄组和男性病例分别占71.15%和70.09%。结论HFRS是河北省发病率最高的病毒性出血热,需重点关注。应进一步加强包括DF和SFTS在内的病毒性出血热输入性病例的监测。
