目的掌握湖南省肾综合征出血热(HFRS)疫情动态以及宿主动物种类、带病毒率等情况,为防制HFRS提供科学依据。方法按照2007年《湖南HFRS监测实施方案》,在全省4个常规监测点和环洞庭湖区5个应急监测点系统开展HFRS流行病学和病原学监测。采用直接免疫荧光法(DFA)检测宿主动物肺组织汉坦病毒(HV)抗原。结果2007年共报告病例705例,发病率1.11/10万,较2006年升高24.72%。4个常规监测点共捕获517只宿主动物,总鼠密度为5.20%,鼠带毒率为0.39%,其中双峰县的黑线姬鼠、小家鼠各1只阳性。5个应急监测点共检测261只宿主动物,总阳性率为2.68%,其中君山区2只东方田鼠、汉寿县3只黄毛鼠和2只黑线姬鼠的肺组织HV抗原阳性。结论湖南省HFRS疫情较2006年有一定程度升高,宿主动物的带毒率较高,需要高度重视,综合防制HFRS。
Objective To investigate the epidemic situation of hemorrhagic fever with renal syndrome (HFRS) and the host animal species and virus rate in Hunan province and provide a scientific basis for the prevention of HFRS. Methods According to the 2007 Hunan HFRS Monitoring Implementation Plan, HFRS epidemiology and etiology monitoring were carried out in 4 routine monitoring points in the province and 5 emergency monitoring points around the Dongting Lake area. Hantavirus (HV) antigen in the lungs of host animals was detected by direct immunofluorescence (DFA). Results A total of 705 cases were reported in 2007, with an incidence of 1.11 / 100 000, up 24.72% from 2006. A total of 517 host animals were captured at 4 routine monitoring points with a total rat density of 5.20% and a rat virulence of 0.39%. One of them, Apodemus agrarius and Mus musculus, was positive in Shuangfeng county. A total of 261 host animals were detected in the five emergency monitoring sites, with a total positive rate of 2.68%. Among them, the HV antigen was positive for lung tissue of two Volendamia vole (Microtus Fortis), three Hamster (Hanshou County) and two Apodemus agrarius. Conclusion The epidemic situation of HFRS in Hunan Province increased to a certain extent compared with that of 2006, and the host animals had a high rate of virulence. Therefore, HFRS needs to be highly valued and comprehensively controlled.
