Abstract: The surveillance was based on the large scale of inverstigation and reseach in Guizhou,by means of combining the steady spots(1984-94; five counties) with the movable spots(1990-95;twenty nine counties). The results showed that:Apodemus agrarius and Rattus norvegicus Berkenhout were extensively prevalent in Guizhou.The former occupied a dominant position in agrarian fields in sixty two counties norih to twenty six degree north latitude and divided into two subspecies:A.a.Mantchuricus in the majority areas as Zunyi etc. and A.a.Ningpoensis in the minority areas of Guizhou as Liping etc. Rattus norvegicus was predominant in residencial areas in Guizhou.Both were main host animals and infectious sources:Apodemus agrarius in the middle, north and east-north part, while Rattus norvegicus in the east-south part of the province. Their density and virus carring rates varied in certain seasons and certain years. HFRS could be effectively controlled by wiping out the host animals and infectious sources.
