摘　　要：目的调查2010年1月—2013年12月皖北地区肾综合征出血热(hemorrhagic fever with renal syndrome,HFRS)疫情的流行趋势,为部队制定野外驻训HFRS防治对策提供依据。方法采用现场流行病学调查、病史及检验结果分析、文献复习等方法调查2010年1月—2013年12月皖北6个地级市的HFRS人群发病率、发病季节和性别等流行病学资料,并对当地健康居民和常驻疫区健康官兵检测病毒Ig G抗体,进行血清流行病学调查。结果 2010年1月—2013年12月,皖北地区累计报告HFRS病例642例,死亡14例;2010、2011和2012年监测点健康人群隐性感染率分别为6.42%、7.14%和7.69%,常驻疫区官兵隐性感染率分别为1.03%、0.93%和1.82%,低于当地人群(P均<0.05),但2013年二者隐性感染率无明显差异,分别为7.02%和5.77%(P>0.05),而同年该驻军野外训练频次有明显增加。结论皖北地区近4年来HFRS疫情基本平稳,但健康人群隐性感染率仍处在较高水平,而2013年驻地部队隐性感染率上升明显,应强化对野外作业官兵保护教育。Objective To investigate the epidemiological features of hemorrhagic fever with renal syndrome（HFRS） epidemic in the northern region of Anhui Province from Jan. 2010 to Dec. 2013, so as to provide evidence for making out prevention countermea-sures of HFRS for troops stationed and training in wild fields. Methods On-spot investigation, analysis of illness history and laboratory findings and reviewing of literatures were used to collect and analyze the epidemiological features, including the occurrence rate, the season of the onset and gender, etc. in HFRS patients in 6 cities of the northern region of Anhui Province from Jan. 2010 to Dec. 2013.An investigation on serological epidemiology was carried by detecting HFRS Ig G antibody using ELISA in healthy residents and healthy armymen stationed in the epidemic areas. Results The cumulative number of HFRS patients reported in the northern region of Anhui Province from Jan. 2010 to Dec. 2013 was 642, and the cumulative death toll was 14. Inapparent infection rates in healthy residents in2010, 2011 and 2012 were 6.42%, 7.14% and 7.69%, respectively, significantly higher than those in healthy armymen stationed（1.03%,0. 93 % and 1. 82 %）（P〈0.05）. However, the inapparent infection rate was not significantly different between the two populations in 2013（7.02% vs. 5.77%）, when the armymen took increasing number of field trainings. Conclusions The occurrence of HFRS remains stable in the northern region of Anhui Province from Jan. 2010 to Dec. 2013, while the inapparent infection rates in healthy residents are higher and the rate increased in the armymen stationed in the region in 2013. Therefore, precaution education should be enhanced among the armymen training in wild fields.
