摘要
目的了解河南省肾综合征出血热的流行特征和流行因素,为全省防治策略提供科学依据。方法采用描述性统计方法对2006～2010年河南省疫情资料进行流行病学分析;在全省设立3个固定监测点,采用夹夜法捕鼠,调查鼠密度、鼠带毒率和带病毒鼠毒指数。结果 2006～2010年全省报告病例1044例,平均发病率为0.22/10万。病例以男性青壮年农民发病居多。春季和冬季各有一个发病高峰,冬峰峰值高于春峰。病例主要分布在豫南的驻马店、南阳、周口和信阳等地,占发病总数的54.70%。混合鼠密度在6.21%～20.43%之间波动,混合带病毒鼠指数在0～0.104之间波动。健康人群平均抗体阳性率为9.50%。结论河南省2006～2010年肾综合征出血热疫情维持在较低水平,但近年有上升趋势,流行因素仍然存在。
Objective The aim of this article is to study the epidemic characters and risk factors of Hemorrhagic fever with renal syndmme（HFRS） in Henan province and provide preventive measures against HFRS.Methods Data on the incidence of HFRS collected from the whole province were analyzed by using the methods of descriptive epidemiology;Data on the density of rats,proportion of rats with virus,index of rats with virus and the human unapparent infcetion rate were collected and analyzed.Results Total 1044 HFRS cases were reported in whole province from 2006 to 2010,with an average in cidence of 2.2 cases per million.Young and middle-aged male farmers were the main victims of these cases.Two peak seasons of affect rate were observed in spring and winter.The value of spring peak is higher than the one of winter peak.The cases are distributed mainly in the Zhumdian,Nanyang,Zhoukou and Xinyang,making up 54.70 percent of the total.The density of mixed species of rats ranged from 6.21～20.43% and the index of mixed species with virus varied from 0 to 0.104.The average human unapparent infection rate was 9.50%in the past five years.Conclusion A lower incidence rate of HFRS in Henan was maintained from 2006 to 2010.However,the rates in some cities were trend to increase and the risk factors still existed.
