摘　　要：目的:分析内蒙古自治区(内蒙古)实施以接种疫苗为主的防治策略10年以来,肾综合征出血热(HFRS)的流行特征,为内蒙古今后HFRS的防治工作提供科学依据。方法:应用Excel软件对2001—2010年HFRS监测资料进行描述流行病学分析。结果:2001—2010年内蒙古累计发病2 640例,年均发病率为1.10/10万,死亡35例,病死率为1.33%,较上个10年发病人数下降了34%。HFRS流行地区有所扩大,但多以散发为主,高发地区仍集中在呼伦贝尔市和巴彦淖尔市。发病集中在秋冬季,11月份一直为高发月份,青壮年仍是发病主体,各年龄组男性发病多于女性,农民发病最多。HFRS发病率呈逐年下降趋势,2007年后维持在1/10万以下的低水平。实施扩大免疫规划的3年较2005—2007年发病人数减少了543例,平均发病率由1.19/10万下降到0.43/10万。结论:自2001年实施以疫苗注射为主的防治策略以来,内蒙古HFRS的发病率和死亡率显著降低。Objective To analyze the epidemiological features of hemorrhagic fever with renal syndrome（HFRS）in Inner Mongolia from 2001 to 2010,where vaccination-based control strategies were carried out,and to provide a scientific basis for prevention and control of HFRS in the future.Methods The monitoring data of HFRS in Inner Mongolia from 2001 to 2010 was statristically analyzed with Excel software.Results A total of 2 640 HFRS cases and 35 deaths reported in Inner Mongolia with case fatality rate 1.33%,the average annual incidence was 1.10/100 000 from 2001 to 2010.The incidence numbers declined by 34%.The epidemics areas of HFRS had expanded,but there was general sporadic distribution,the HFRS cases mainly concentrated in the Hulunbeier City and Bayannaoer City.The most infections concentrated in the autumn-winter season,the peak was still in November.The cases mainly distributed in the young and adult.The incidence reported in males was more than that in the females at all groups.Farmer had the highest incidence in all occupations.The incidence of the HFRS began to show descending trend year by year,the annual incidence of the HFRS basically maintained at the low level of less then 1/100 000 after 2007,after three years of implementing expanded program on immunization（EPI）,the incidence numbers declined by 543,the average annual incidence declined to 0.43/100 000 from 1.19/100 000,compared with last three years.Conclusion Implement vaccination-based control strategies had been performed since 2001,and the incidence and mortality of HFRS have greatly decreased in Inner Mongolia.
