EBOLA - Le bilan de l'épidémie de fièvre hémorragique en grande partie due au virus Ebola en Afrique de l'Ouest ne cesse de s'aggraver avec plus de 1300 cas et 729 morts au 27 juillet, dont 57 en 4 jours, a indiqué jeudi 31 juillet l'OMS. "Entre les 24 et 27 juillet, un total de 122 nouveaux cas (confirmés, probables et suspects) ainsi que 57 décès ont été notifiés en Guinée, au Liberia, au Nigeria et en Sierra Leone", a précisé l'OMS dans un communiqué.
Ces chiffres font apparaître une augmentation en 4 jours de 8,5% du nombre des décès et de 10,1% du nombre des cas depuis le précédent bilan de l'OMS. "La tendance (...) reste incertaine" alors que l'épidémie continue de se propager au sein des communautés et touche aussi désormais les soignants, avertit l'OMS.
Hémorragies, vomissements et diarrhées
Au total, à la date du 27 juillet, l'OMS a comptabilisé 1323 cas de fièvre hémorragique (909 confirmés Ebola) dont 729 se sont soldés par un décès (485 confirmés Ebola). La Guinée, d'où l'épidémie est partie, compte 460 cas de fièvre hémorragique (336 confirmés Ebola) dont 339 morts (218 confirmés Ebola). Le Liberia a dénombré 329 cas (100 confirmés) dont 156 mortels (72 confirmés). La Sierra Leone a enregistré pour sa part 533 cas (473 confirmés) dont 233 morts (195 confirmés). Au Nigeria, pour l'instant seul un cas mortel a été enregistré.

L'OMS ne recommande toujours pas que des restrictions aux voyages ou aux échanges commerciaux soient imposées à la Guinée, au Libéria, à la Sierra Leone ou au Nigeria sur la base des informations actuellement disponibles concernant cette épidémie qui commence à inquiéter la France et le reste du monde. Le virus Ebola se manifeste notamment par des hémorragies, des vomissements et des diarrhées. Son taux de mortalité peut aller de 25 à 90% et il n'existe pas de vaccin homologué. Il se transmet par contact direct avec le sang, les liquides biologiques ou les tissus de personnes ou d'animaux infectés.

The World Health Organization has warned that Ebola could spread beyond hard-hit Guinea, Liberia and Sierra Leone to neighbouring nations, but insisted that travel bans were not the answer. To date, there have been 635 cases of haemorrhagic fever in Guinea, Liberia and Sierra Leone, most confirmed as Ebola. A total of 399 people have died, 280 of them in Guinea.

The death toll in West Africa\'s Ebola outbreak has risen to 603, the World Health Organization (WHO) said last week, with 68 new fatalities mostly in Sierra Leone and Liberia. The UN health agency said the new deaths were recorded between July 8 and 12, and that 52 of them were in Sierra Leone, 13 in Liberia and three in Guinea, which had previously borne the brunt of the outbreak. Ebola first emerged in 1976 in what is now the Democratic Republic of Congo, and is named after a river in that country.

The owners of a \"maquis,\" a small African restaurant in Kobakro, outside Abidjan, which used to serve bush meat, hold up the different types of meat and fish they now offer to their clients. The Ministry of Health has asked Ivorians, \"particularly fond of porcupine and agouti,\" a small rodent, to avoid consuming or handling bushmeat, as an unprecedented Ebola epidemic hit West Africa. The virus can spread to animal primates and humans who handle infected meat -- a risk given the informal trade in \"bushmeat\" in forested central and west Africa. (Issouf Sanogo/AFP/Getty Images)
