| 本文讨论了天台县流行性出血热(EHF)在平原、丘陵、山区等不同地形的宿主动物、疫源地类型与发病的关系。基本上明确了平原地区以黑线姬鼠和褐家鼠为主要宿主动物的混合型疫源地,其鼠肺EHF抗原阳性率高,是EHF发病严重地带,且健康人群隐性感染率亦高。随着海拔高度的升高,丘陵、山区逐渐形成以褐家鼠为主的疫源地,且鼠肺EHF抗原阳性率明显降低,EHF的发病及健康人群隐性感染水平都低。 |

| The data showed that there was acrrelation between EHF and host animals as well as types of natural foci in plains，hills and mountain areas of Tian Tai county.lt was clear that the main host animals were R.norvegicus and A. agrarius in plain area, so there are mixture foci of R.norvegicus and A.agrarius in the abore areas. The morbidity of EHF and the positive rate of mouse lung antigen as well as the inapparent infections rate of healthy population were high in plains. As the atitude elevated, it gradually formed a natural focus of R. norvegicus as the main host animal in hills and mountaim areas. The positive rate of the mouse lung antigen diminished sharply.Both the incidence rate of EHF and the inaPParent infection rate of healthy population were lower. |
