福建省肾综合征出血热疫情及宿主动物监测分析

Surveillance and analysis on HFRS epidemic situation and the host animals in Fujian Province

目的掌握福建省肾综合征出血热(HFRS)疫情动态,为防治工作提供科学依据。方法对全省疫情报告进行统计分析;计算各地鼠密度及鼠种构成,应用免疫荧光法(IFA)对样本进行病毒抗原抗体检测。结果 2009年全省报告203例HFRS,发病率0.56/10万。疫情分布在54个县、市(区),松溪、泰宁和周宁县发病率位居前3位,云霄、南靖和华安县为新增发病地区。监测显示室内平均鼠密度5.8%,褐家鼠为主要鼠种;首次从安溪、龙海、沙县及漳浦褐家鼠中检出病毒抗原。结论 2009年福建省HFRS疫情明显上升,疫区有扩大趋势;主要宿主动物仍为褐家鼠,应切实做好灭鼠工作,推广使用双价疫苗。

Objective To study the epidemic situation of hemorrhagic fever with renal syndrome（HFRS） in Fujian for the disease control and prevention.Methods The data of HFRS were collected and analyzed.Rats density and specie composition were investigated.IFA method was used to detect the antigen and antibody for the samples.Results Totally 203 cases of HFRS were reported in 2009 in Fujian.The incidence of HFRS was 0.56/100000.The cases were mainly in Songxi,Taining,Zhouning County.The new epidemic areas were observed in Yunxiao,Nanjin and Huaan County.Surveillance of rodents showed that mean rodent density was 5.8% for indoor areas,and the dominant species was Rattus norvegicus.The antigen was found out firstly from Anxi,Longhair,Shaxian and Zhangpu County.ConclusionThe epidemic situation and areas of HFRS was significantly increased and enlarged in 2009.Rattus norvegicus was still the main host.The rat control and immunization of bivalent vaccine should be promoted for the disease control.
