阜阳市2006～2010年肾综合征出血热监测结果分析

目的分析阜阳市2006～2010年肾综合征出血热（HFRS）的流行特点和趋势,为制定防制策略提供依据。方法收集2006～2010年HFRS疫情资料,描述其流行病学特征。对标本进行HFRS抗原、抗体检测。结果 2006～2010年全市共报告HFRS病例170例,年平均发病率0.40/10万。各月均有报病,发病高峰为11月份,占发病总数的27.65%。最大年龄79岁,最小年龄11岁,发病主要分布在30～60岁年龄段,占总数的74.71%。男多于女,男女之比为3.36：1。职业以农民为主,占总发病数的79.41%。室内鼠密度平均为4.96%,鼠种构成以小家鼠为主;野外鼠密度平均为6.83%,鼠种构成以黑线姬鼠为主。室内鼠肺带毒率为2.36%;野外为6.58%。结论阜阳市肾综合征出血热发病率稳定在低发水平;传染源以姬鼠型为主;以秋末冬初为主;做好防鼠灭鼠及重点人群的疫苗接种工作是降低发病的有效手段。

Analysis On The Surveillance Of Hemorrhagic Fever With Renal Syndrome In Fuyang City From 2006 To 2010

Objective To analyze the epidemiological characteristics and the trends of hemorrhagic fever with renal syndrome（HFRS） in Fuyang from 2006 to 2010,and provide theoretic basis for formulating the control measures.Methods Epidemiological data of HFRS from 2006 to 2010 were collected to describe the epidemiologic characteristics of HFRS.The specimens were used for HFRS antigen and antibody detection.Results The disease presented sporadic feature,a total of 170 HFRS cases was reported in whole city from 2006 to 2010,and the annual average incidence was 0.4/lakh.Cases were reported in each month,and the peak incidence occurred in November which accounted for 27.65% of the total cases.Onset age of the cases ranged from 11 to 79,and predominated within the 30~60 age groups which accounted for 74.71%.The number of cases was more in male than in female,and the ratio of male to female was 3.36：1.Of all the HFRS infections,79.41% were peasants.The indoor rat density was 4.96% on average,and most of them were mus musculus.The outdoor rat density was 6.83%,and most of them were apodemus agrarius.The virulence carriage rate of indoor rat lungs was 2.36%,and that of outdoor rat lungs was 6.58%.Conclusion The HFRS incidence rate in Fuyang maintained at a low level.The main source of infection was apodemus agrarius.The epidemic season was mainly in late autumn and early winter.Doing well in rats prevention and killing and vaccination among key population were the effective measures to decrease the incidence.
