[Analysis on distribution of epidemic hemorrhagic fever in different area].
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. It was clear that the main host animals were R. norvegicus and A. agrarius in plain areas, so there are mixture foci of R. norvegicus and A. agrarius in the above 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 attitude 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.
