目的 探讨肾综合征出血热 (HFRS)流行趋势及其发病因素 ,为今后科学地指导防治工作、有效地预防控制HFRS的发生与流行 ,提供科学依据。方法 应用流行病学调查、血清流行病学、动物流行病学方法研究HFRS人间疫情、鼠间疫情 ,阐明流行特点和流行因素。结果 黑线姬鼠、大仓鼠、褐家鼠、黄胸鼠为主要传染源 ,鼠类有 1目 2科 8种 ,另有食虫目鼠句鼠青科的臭鼠句鼠青、麝鼠句 2种 ,社鼠和中华姬鼠为本市首次捕获。重疫区多发生海拔 2 0～ 40m平原低洼潮湿地带 ,有明显沿水系分布特点 ,且疫情稳定而局限 ;流行季节11月至翌年 2月为主 ,以农村男性青壮年为高危人群 ;动物监测、人群监测可作为疫情预测预报的指标 ,干支流交汇处潮湿低洼易发生爆发流行是今后指导防治工作的重点 ;爆发流行控制措施以灭鼠为主 ,稳定的重疫区高发人群接种HFRS双价疫苗。结论 疫情处于相对稳定低发时期 ,且具有潜在流行趋势 ,应继续对重点地区做好监测与控制工作。
Objective To investigate the epidemic trend of hemorrhagic fever with renal syndrome (HFRS) and its etiological factors and provide a scientific basis for the future scientific guidance and prevention of HFRS and the effective prevention and control of the occurrence and prevalence of HFRS. Methods Epidemiological investigation, serological epidemiology and animal epidemiology were used to study the epidemic situation of HFRS and the outbreak of epidemic in mice. The epidemic characteristics and epidemic factors were clarified. Results Apodemus agrarius, hamster, Rattus norvegicus and Rattus flavipectus were the major infectious agents. There were 8 species of 1 family, 2 families and 2 families of rats. Two species, community rats and Apodemus for the first time capture the city. In the heavy epidemic area, there are many low-lying wetlands with altitude of 20-40m, which are obviously distributed along the river system, and the epidemic situation is stable and limited; the epidemic season is mainly from November to February next year, and the young men and women in rural areas are at high risk; animal monitoring , Crowd monitoring can be used as an indicator of the epidemic forecast and forecast, epidemic of dry branches and tributaries prone to outbreak epidemic is the focus of future guidance and prevention work; outbreak of epidemic control measures to rodent control-based, vaccine. Conclusion The outbreak is in a period of relatively stable and low incidence, with potential epidemic trends. Monitoring and control of key areas should continue to be conducted.
