[Epidemiology and prophylaxis of viral hemorrhagic fevers]

A review of virus hemorrhagic fevers has been carried out. The different etiological agents belong either to arboviruses, either to related genera. The authors recall the main epidemiological aspects, in particular the transmission ways and means. Prophylaxis is to be taught of which behaviour can be taken in regard to a questionable case as well as permanent measures of control on the field. Although an extreme carefulness is necessary, the experience of the recent past years indicate that classical measures of isolation are generally adequate to prevent any emergence of secondary cases.
