First report of an endemic area of EHF in Baoding prefecture

35 sporadic Epidemic Hemorrhagic Fever (EHF) cases were identified and confirmed by means of IFA serologic test in Baoding prefecture from May 1984 to May 1986. The data indicated that the Positive rates of EHF-antigen in R.norvegicus was 4.85%; in A.agrarius it was 1.92%; in C.triton, 0.79%; and in M.musculus was 0.51% respectively in the focus of EHF. It was suggested thought that R.norvegicus might be the main reservoir in Baoding prefecture. No EHF antigen was detected in rodents of the villages where no EHF cases was confirmed. The Positive rate of EHF antibody was 1.37% in healthy population in endemic area of EHF. The Positive rate of female was higher than that of male. No serologically positive serum was found in the nonendemic areas for EHF.
The above results showed that Baoding prefecture was an endemic area of EHF.
