title: [Viral haemorrhagic fever].
abstract: Viral haemorrhagic fever denotes various kinds of febrile illness caused by certain viruses which often presents with bleeding tendency and occasionally shock. Out of these, the four maladies, Lassa fever, Ebola haemorrhagic fever, Marburg haemorrhagic fever and Crimean-Congo haemorrhagic fever which are endemically present in Africa or eastern Europe, are known to be such diseases with high man-to-man communicability. These four haemorrhagic fevers are, therefore, designated as special conditions requiring isolation during the period when the infected patients are shedding the viruses, not only in Japan but also in many other countries. We have so far only one such case of Lassa fever who returned to Japan from Sierra Leone in 1987. Some haemorrhagic fevers including dengue (haemorrhagic) fever and hantavirus infections (e.g. haemorrhagic fever with renal syndrome) are not known to be man-to-man transmissible and requiring no isolation. We have a number of dengue and dengue haemorrhagic fevers here in Japan today among imported febrile cases from tropical or subtropical countries. Every physician should take viral haemorrhagic fevers into consideration as one of the possibilities in diagnosing patients returning from overseas travel.
