Viral hemorrhagic fever (VHF) is defined as virus infections that usually cause pyrexia and hemorrhagic symptoms with multiple organ failure. VHF includes following viral infections: Ebola hemorrhagic fever (EHF), Marburg hemorrhagic fever (MHF), Crimean-Congo hemorrhagic fever (CCHF) and Lassa fever. In particular, the causative agents of EHF, MHF, CCHF, and Lassa fever are Ebola, Marburg, CCHF, Lassa viruses, respectively, and regarded as biosafety level-4 pathogens because of their high virulence to humans. Recently, relatively large outbreaks of EHF and MHF have occurred in Africa, and areas of EHF- and MHF-outbreaks seem to be expanding. Although outbreaks of VHF have not been reported in Japan, there is a possibility that the deadly hemorrhagic fever viruses would be introduced to Japan in future. Therefore, preparedness for possible future outbreaks of VHF is necessary in areas without VHF outbreaks.
