[Ebola virus three years later (author's transl)]

Abstract

Sporadic cases and data from serologic surveys give evidence that Ebola virus is still active in Northern Zaïre after the first outbreak in 1976. It is also active in Southern Sudan where it is, from August 1979, responsible of a new epidemic focus. In addition, serological surveys demonstrate that its dispersion area comprises several other african countries. Physicians practising in central Africa must be aware of this fact. Serological test is necessary to confirm the diagnosis. This confirmation is necessary to obtain convalescent patient plasma, the only specific treatment. The clinical, epidemiological and virological aspects of Ebola virus disease are reviewed as well as precautionary measures to be taken by medical and nursing staff to avoid infection.
