[Epidemics of Ebola haemorrhagic fever in Gabon (1994-2002). Epidemiologic aspects and considerations on control measures]. / Les epidémies de fièvre hémorragique due au virus Ebola au Gabon (1994 - 2002): aspects epidémiologiques et réflexions sur les mesures de contrôle.

ABSTRACT

Based on the description of the four Ebola haemorrhagic fever epidemics (EHF) occurred in Gabon between 1994 and 2002, the authors are considering the cultural and psycho-sociological aspects accounting for the difficulty to implement control measures. On the whole, the result of these raging epidemics came up to 207 cases and 150 dead (lethality 72%). Analysing precisely the aspects of the third epidemic and pointing up the possible factors explaining its spreading far beyond its epicentre, the authors bring about the limits of measures not always understood by local populations. The discussion will deal with the possibilities of a better surveillance, a quick management of intervention means including a regional permanent pre-alert and taking into account the issue raised by the possible Ebola virus endemic.
