Resumo(s)
O vírus Ébola é um vírus de ácido ribonucleico (ARN), endémico em certas regiões da África Subsariana e agente causal de um quadro severo de febre hemorrágica no homem. Tem sido responsável desde 1976 por inúmeras epidemias, com taxas de mortalidade que variam dos 30 a 90%, das quais, nenhuma foi tão grave e de proporções tão drásticas, como a que se vive actualmente no continente africano, afectando maioritariamente a Guiné-Conakry, a Serra Leoa e a Libéria. São vários os agentes farmacológicos que estão em desenvolvimento, mas dada a inexistência de uma cura para a doença, a terapia de suporte continua a assumir uma importância fulcral para o prognóstico dos doentes. Tendo em conta o impacto que a doença por vírus Ébola pode ter na saúde pública, pretende-se com este artigo, fazer uma revisão desta entidade, em particular, dos seus aspectos epidemiológicos e clínicos.
Ebola is an RNA virus that is endemic in certain sub-Saharan regions of Africa and is the causative agent of a highly lethal haemorrhagic fever in humans. Despite being responsible for numerous outbreaks since its discovery in 1976, with case fatality rates ranging from 30 to 90%, none of them was as severe and extensive as the present one which is mainly affecting the countries of Liberia, Guinea and Sierra Leone. There has been a development concerning therapeutic agents for Ebola disease, but while none of them curative, the supportive care remains the most important weapon concerning the prognosis of the patient. Surging as an emergency for public health, this article proposes to review the current knowledge about the virus, focusing mainly in the epidemiologic and clinical aspects of the disease.
