摘要
目的了解和掌握天津市2000-2011年肾综合征出血热(HFRS)的流行特征,为制定相关防控措施提供依据。方法对天津市2000-2011年HFRS疫情资料采用描述流行病学方法进行统计分析。结果 2000-2011年天津市共出现一波流行高峰,2002年发病数和发病率达到顶峰。2003年起发病率迅速下降。12年间累计报告HFRS病例1691例,死亡25例,每年平均发病率1.53/10万;城区发病率高于其他地区发病率(χ2=95.482,P=0.000),病例以男性青壮年为主,职业分布以农民和工人为主,发病时间集中在春季。鼠密度和鼠带病毒率指标自2004年出现明显下降趋势,近年稳定维持在较低水平,鼠带病毒指数与人群发病水平呈现正相关(r=0.886,P=0.000)。结论天津市HFRS疫情近年呈现持续平稳状态,但自然疫源性疾病的监测工作需要长期开展,积极掌握信息才能科学、及时、有效的指导防控工作。
Objective To understand the epidemiological characteristics of hemorrhagic fever with renal syndrome（HFRS） in Tianjin from 2000 to 2011 and provide scientific evidence for prevention and control for the disease.Methods Descriptive epidemiological analysis was conducted on the surveillance data of HFRS in Tianjin during this period.Results A total of 1691 HFRS cases,including 25 deaths,were reported with the average annual incidence being 1.53/lakh.The incidence peaked in 2002 and began to decline rapidly in 2003.The incidence in urban area was higher than other areas（χ2=95.482,P=0.000）.Most cases were young males and mainly distributed in framers and workers.The disease mainly occurred in spring.Rat density and rat infection rate began to decline obviously in 2004 and remained at low level in recent years.The rat infection rate was positively correlated with the incidence of the disease in human（r=0.886,P=0.000）.Conclusion Although the incidence of HFRS remained stable in Tianjin,it is still necessary to conduct the surveillance of this natural focus disease in the future.
