流行性出血热(EHF)是一种以鼠类为主要传染源的自然疫源性疾病。本病的流行强度与宿主动物的种群密度、带毒动态以及人群接触宿主动物的频率等有关。牡丹江市是EHF老疫区。自1984—1986年,我们对不同地形疫区的鼠种分布、鼠带毒率等情况进行了调查,现将结果报告如下。1 方法1.1 收集我市各地鼠情监测资料 Epidemic haemorrhagic fever (EHF) is a naturally foci of disease with murine as the main source of infection. The prevalence of the disease and host population density of the virus, dynamic and infected population exposure to host the frequency of the host. Mudanjiang is the EHF old epidemic area. From 1984 to 1986, we investigated the distribution of murine species and the virulence rate in different endemic areas. The results are reported as follows. 1 Methods 1.1 Collect rodent surveillance data throughout the city
