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。
Objective To analyze the epidemiological features and trends of hemorrhagic fever with renal syndrome (HFRS) in Fuyang City from 2006 to 2010, and provide basis for making prevention and control strategies. Methods The epidemic data of HFRS from 2006 to 2010 were collected and their epidemiological characteristics were described. The specimens were tested for HFRS antigen and antibody. Results A total of 170 HFRS cases were reported in the city from 2006 to 2010, with an average annual incidence of 0.40 / 100,000. Each reported a disease, the peak incidence in November, accounting for 27.65% of the total incidence. The oldest was 79 years old, the youngest was 11 years old. The incidence mainly distributed in the 30-60 age group, accounting for 74.71% of the total. More men than women, the ratio of men to women is 3.36: 1. Occupation of peasants, accounting for 79.41% of the total number of cases. The indoor density of rats was 4.96% on average, and the species of Mus musculus was dominated by Mus musculus. The average density of mice in the field was 6.83%. The main species was Apodemus agrarius. Indoor rat lung poisoning rate was 2.36%; field was 6.58%. Conclusions The incidence of hemorrhagic fever with renal syndrome in Fuyang is stable at a low level. The main source of infection is Apodemus agratius, mainly in the late autumn and early winter, and good anti-rodent control and vaccination of key populations are effective in reducing the incidence. means.
