Abstract: The results of three years rodent infestation surveillance in some cities and counties in Hu-Bei province has been analysed. The rodent population consisted mainly of three species, that is Rattus norvegicns, Rattus flavipectus, and Mus musculus. The distribution regularity of Rat, having intimate contact with men and transmission of epidemic Hemorrhagic fever (EHF), has been basically found out. It was known that there are two peaks of Rat's density, namely in April-May and Sept. -Oct., which is identical with the peak of Human EHF. but the Rat's peaksis Usually ahead of Human EHF outbreak, These provided a scientific evidence for the disease prevention and rodent control. The density had defined through the rodent controlling and prevention of the disease rely on a large scale decline of Rat's density and decline of the incidence of Human EHF rely on the result of rodent and disease surveillance.
