| 摘 要： | 目的 了解内蒙古呼伦贝尔市肾综合征出血热(hemorrhagic fever with renal syndrome,HFRS)流行现状,给制定预防决策提供依据。 方法 对2006-2011年全市疫情资料、鼠间监测资料和2001年以来疫苗接种效果进行分析。 结果 2006-2011年全市共报告HFRS病例520例,发病率波动在1.40/10万~5.59/10万之间,年平均发病率为3.17/10万,疫情总体呈逐年下降趋势。疫情主要分布于8个旗市,其中以莫旗和鄂伦春旗最高,分别占发病数的41.89％和36.68％,1月有个小高峰,秋冬季(9-12月)为发病最高峰,占全年总病例数的70.19%。发病年龄组主要集中在20~55岁青壮年组,占全年龄组的85.19%,男女性别比为3.12∶1。职业以农民最高,占69.81%;野外鼠类(带病毒率3.92%,带病毒指数0.05)以黑线仓鼠最高,居民区鼠类(带病毒率1.79%,带病毒指数0.05)以小家鼠最高;春季(带病毒率3.01%,带病毒指数0.05)以黑线仓鼠最高,秋季(带病毒率2.69%,带病毒指数0.06)以小家鼠最高。通过对高发病地区莫旗和鄂伦春旗接种疫苗前后发病率进行比较分析,莫旗年平均发病率下降了23.94%,鄂伦春旗年平均发病率下降了27.15%。 结论 初步证明了大面积应用疫苗接种作为控制和降低HFRS发病率和死亡率的防治策略是科学的和切实可行的。但近几年鼠密度和鼠带病毒率一直维持在较高水平, HFRS传播流行风险依然存在,应继续落实高流行区高危人群免疫等综合性防治措施。

| Abstract: | Objective To understand the incidence trend of hemorrhagic fever with renal syndrome(HFRS) in Hulunber and provide evidence for the disease prevention and control.Methods The analysis was conducted on the incidence data of HFRS from 2006 to 2011 and the surveillance data in rats,and the evaluation on vaccination effect since 2000 was made.Results A total of 520 HFRS cases were reported during this period.The incidence ranged from 1.40/lakh to 5.59/lakh(average annual incidence: 3.17/lakh) and declined gradually.The disease was mainly distributed in 8 flags and the case numbers in Moqi and Elunchunqi were highest,accounting for 41.89% and 36.68% respectively.The cases occurred in sub-peak period(January) and in peak period(September-December) accounted for 70.19% of the annual total.The cases were mainly distributed in age group 20-55 years,accounting for 85.19%.The male to female ratio of the cases was 3.12∶1.Farmers were the population affected mostly with the cases accounting for 69.81% of the total.For the rat in open field,the infection rate and index were highest in Cricetulus barabensis(3.92%,0.05),for the rats in residential area,the infection rate and index were highest in Mus musculus(1.79%,0.05).The rat infection rate and index were highest in spring in Cricetulus barabensis(3.01%,0.05) and highest in autumn in Mus musculus(2.69%,0.06).The comparison of incidences before and after vaccination in Moqi and Elunchunqi indicated that the incidence declined by 23.94% in Moqi and 27.15% in Elunchunqi.Conclusion It was demonstrated that mass vaccination was effective and feasible in reducing incidence and death of HFRS.Because the rat density and infection rate remain to be high in recent years,the risk of HFRS spread still exist.It is necessary to continue the vaccination in high risk population in high risk area. |
