本文应用描述流行病学、地理流行病学血清学和病源学等方法,明晰了呼盟地区55年以来EHF疫情发展的总趋势是疫区逐渐扩大,80年代后期发病不断上升,由于人群免疫力极低易形成暴发疫情。该地区啮齿动物种群构成为4目6科15种,其优势种野外为黑线姬鼠,居民区为小家鼠。传染源和宿主动物构成为1目2科5种,主要宿主动物和传染源为黑线姬鼠。疫区的分布具有相对集中性,与地形、地势、地表植被,川溪河谷分布、气温及降水等自然地理因素有关。疫区分布占地区总面积的50％,重疫区比较局限和稳定,疫源地和疫区按流行病学方法可划分为野鼠型。
In this paper, epidemiology, epidemiology, epidemiology and etiology were used to clarify the general trend of EHF epidemics in Huemeng area since 55 years. The epidemic area gradually expanded and the incidence gradually increased in the late 1980s. Due to the population immunity Very easy to form an outbreak. The rodent population in the area is composed of 4 orders, 6 families and 15 species. The dominant species is Apodemus agrarius in the field and the Mus musculus is the residential area. Infectious sources and host animals are composed of 1 order, 2 families and 5 species, and the main host animal and infection source are Apodemus agrarius. The distribution of the epidemic area is relatively concentrated, with the topography, topography, surface vegetation, distribution of Chuanxi River valley, temperature and precipitation and other natural and geographical factors. Epidemic area accounted for 50% of the total area, heavy endemic areas more limited and stable, epidemic areas and epidemic areas can be divided into wild-type epidemic.
