摘要
目的了解内蒙古自治区(内蒙古)肾综合征出血热(HFRS)的流行病学特征及宿主动物疫情动态,为制定相关防控策略和措施提供依据。方法采用描述性流行病学方法对2016-2020年中国疾病预防控制信息系统中内蒙古HFRS疫情资料进行分析,采用SPSS 22.0软件进行秩和检验、线性相关回归分析以及聚类分析。结果2016-2020年全区9个盟(市)累计报告HFRS病例572例,死亡5例,发病率为0.45/10万,死亡率为3.96×10^(-3)/10万。HFRS流行呈秋冬季发病高峰;发病年龄主要集中在25~54岁,农民占62.24%,男女性别比为3.43∶1;高发地区主要集中在东部地区的呼伦贝尔市,占全区病例数的67.66%。巴彦淖尔市人群中HFRS的隐性感染率平均为6.06%。莫力达瓦达斡尔族自治旗鼠带病毒率为10.34%。结论2016-2020年内蒙古地区HFRS疫情整体较上一个5年有所下降,而呼伦贝尔市的疫情仍然比较严重,应采取有效的预防控制策略和措施加强对该地区疫情的防控。
Objective To investigate the epidemiological characteristics of hemorrhagic fever with renal syndrome(HFRS)and the epizootic situation in host animals in the Inner Mongolia Autonomous Region(Inner Mongolia),China,and to provide a basis for formulating relevant prevention and control strategies and measures.Methods The descriptive epidemiological method was used to analyze the data of HFRS epidemics in Inner Mongolia from 2016 to 2020 from the National Infectious Disease Report Information Management System.SPSS 22.0 software was used to perform the rank sum test,linear correlation analysis,regression analysis,and cluster analysis.Results From 2016 to 2020,a total of 572 cases were reported in 9 leagues/cities of Inner Mongolia,including 5 deaths,with an incidence rate of 0.45/100000 and a mortality rate of 3.96×10-3/100000.The epidemics of HFRS peaked in autumn to winter,and mainly affected the population aged between 25 and 54 years.Farmers accounted for 62.24%of the total cases.The ratio of male to female was 3.43:1.High incidence areas were mainly concentrated in Hulun Buir in eastern Mongolia,where the cases accounted for 67.66%of the total number.The mean inapparent infection rate of HFRS was 6.06%amongpeople in Bayannur.The virus-carrying rate of rodents was 10.34%in Morin Dawa Daur Autonomous Banner.Conclusion The epidemic situation of HFRS in Inner Mongolia from 2016 to 2020 was generally milder than that in the last five years,but Hulun Buir is still in a relatively severe situation,requiring enhanced effective strategies and measures to control the epidemic.
