摘　　要：目的分析宝鸡市2005-2013年肾综合征出血热（HFRS）疫情流行病学特征,评估阶段性防控效果,为进一步制定防制措施提供依据。方法对2005年1月1日至2013年12月31日全市HFRS病例进行流行病学分析,计算HFRS疫苗累计接种率。结果 2005-2013年共报告HFRS病例2233例,死亡15例,年平均报告发病率为4.22/10万,2012年为HFRS高发年;男女性别比为3.02∶1,病例主要集中在40~59岁农民;10月至次年1月为高发季节,夏收季节为一流行小高峰;发病年龄构成后移,表现为〉60岁人群发病数增加。监测点鼠密度波动在0.24%~15.17%之间;全市双价HFRS疫苗累计接种率为82.49%。结论全市控制HFRS取得显著进展,发病年龄后移为宝鸡市HFRS防控提出新的课题。Objective To analyze the epidemiological characteristics of hemorrhagic fever with renal syndrome（HFRS）and to assess its periodic prevention and control effects in Baoji, Shaanxi province, from 2005 to 2013, and to provide reference data for further developing prevention strategies.MethodsAn epidemiological analysis was performed on HFRS patients throughout the city from January 1, 2005 to December 31, 2013. The cumulative vaccination rate for HFRS was calculated.ResultsThere were 2233 cases of HFRS reported in Baoji during 2005-2013, including 15 deaths. The average annual reported incidence of HFRS was 4.22/100 000, and 2012 was identified as a high-incidence year. Among the HFRS patients, the male-to-female ratio was 3.02∶1, and most were 40-59-year-old peasants. Peak season lasted from October to January in the next year, and a small prevalence peak occurred in the summer harvest season. The age composition of HFRS onset shifted towards an older age, with an increasing proportion of those older than 60 years. The density of rodents at the monitoring points fluctuated between 0.24% and 15.17%. The cumulative vaccination rate with bivalent HFRS vaccine in the whole city was 82.49%.ConclusionBaoji has achieved significant effects in prevention and control of HFRS. However, the increasing proportion of HFRS patients towards an older age prompts a new challenge for prevention and control of this disease in the city.
