Abstract: The factors of transmission of epidemic heamorrhagic fever (EHF)among mice were investigated in wild-rodent-type focus of EHF in Jiangsu province in December 1987. The antigenic components of EHF virus isolated from mice and mites in the same litter were analyzed bY immunoblotting technique, the results were identical. Analysing the data with multiple regression mode, significant regression relationship were found between four independent variables including the number of mice each litter, the percentage of skin damage, the positive rate of antigen in remained food of litter andthe number of mite and each of the following dependend variables including the positive rates of antigen/antibody and the total infected rate of EHF in mice. Further analysis showed that skin damage was the first factor of transmission in wild-rodent-type focus of EHF among mice, contacting closely among mice and biting by mites were the second, there were no relationship between the transmission and consuming the food polluted by EHF antigen.
