近年的研究证实,多种鼠和其它小兽是流行性出血热(EHF)的宿主动物和传染源,其中最为主要的是黑线姬鼠、褐家鼠和大林姬鼠。张云等人在控制EHF疫源地的五项指标中指出,鼠密度和鼠EHF抗原阳性率,可代表EHF的传播力,在疫源地中起主导作用,而发病率则反映鼠间的EHF已构成鼠——人传播。考虑到发病率直接受
In recent years, studies have confirmed that many kinds of mice and other small animals are host animals and source of infection of epidemic hemorrhagic fever (EHF). The most important ones are Apodemus agrarius, Rattus norvegicus and Apodemus agrarius. Zhang Yun et al. Pointed out in the five indicators for controlling EHF foci that rat density and the positive rate of murine EHF antigen could represent the transmitting force of EHF and play a leading role in the foci while the incidence reflects the inter-mouse EHF has formed a rat-to-human transmission. Taking into account the incidence directly affected
