Epidemic analysis of HFRS in Gongzhuling City from 2009-2012

目的探讨肾综合征出血热（HFRS）的流行规律与流行趋势，为制定防治措施提供科学依据。方法对公主岭市2009--2012年HFRS疫情资料进行分析。结果2009--2012年共发病117例，无死亡，各年发病率分别为3．5486／10万、2．7858／10万、2．7436／10万和1．7184／10万，年均发病率为2．6917／10万。发病男性多于女性，男女发病性别比为5．88：1；发病年龄集中在20～49岁，占发病总数的87．18％；从农民发病84例，占发病总数的71．79％；每年的1—6月为发病高峰，10—12月为发病小高峰，2个发病高峰期间共发病94例，占发病总数的80．34％。结论该市近几年HFRS发病率逐年下降，提高重点人群HFRS疫苗接种率和积极灭鼠是控制出血热疫情的关键。

[ Objective ] To explore the epidemic rules and trend of hemorrhagic fever with renal syndrome （HFRS） , and provide scientific basis for making control measures. [ Methods] The epidemic data of HFRS in Gongzhuling City from 2009-2012 were ana- lyzed. [ Results] A total of 117 cases of HFRS were reported from 2009-2012 , without death case, the annual incidence rate was 3. 548 6/100 000, 2.785 8/100 000 , 2. 743 6/100 000 and 1. 718 4/100 000, respectively ,with 6.87/100 000 in average. The incidence of male was more than female, the gender ratio of male to female was 5.88：1. Patients aged 15- 55 years accounted for 87.18% of total cases. Peasants accounted for 71.79% of total cases. The peak incidence appeared in January to June, and the smaller one in October-December, with 94 cases （80.34%） between 2 peaks.
