title: [Tick-borne viruses in tropical area (author's transl)].
abstract: Arboviruses, transmitted by ticks and pathogenic to man in tropical areas, are discussed. They are considered according to, first the faunal region in which they can be found, then the type of syndrome they cause. The greater part is of little medical importance, some are noxious but of a rare occurrence (Thogoto, Wanowrie, Langat) or geographically restrained (Kyasanur forest disease), so the Crimean-Congo hemorrhagic fever is the only infection to show a notorius importance. As severe in the tropics of the oriental faunal region (Pakistan, India) as it is Europe, it seems to be of little importance in the afrotropical faunal region. Nevertheless, its severity remains to be ascertained by the means of extensive serological surveys and by taking in account this virus in presence of every hemorrhagic syndrome.
