【Abstract】 Objective] To provide scientific gist for prevention and control of epidemic hemorrhagic fever (EHF) by etiological studies. [Methods] Kinds of reservoir hosts of EHF, transmission route, geographic epidemiology, types of pestilential area of EHF and new-type EHF virus were studied by etiological methods, serological, RT-PCR and sequencial determinations. [Results] 32 strains of EHFV were isolated from 9 kinds of hosts. Aerosol could transmit EHF in experimental animals. New-type of EHF virus was detected in mountainous areas. [Conclusion] Our province is an epidemic area of EHF with multiple-hosts, among which rattus type of EHF is predominant.更多还原
