Abstract

Ebola virus disease (EVD) has a high fatality rate; currently lacks a treatment or vaccine with prov­en safety.  In response, the World Health Organi­zation has declared the Ebola outbreak in West Africa to be a Public Health Emergency of International Con­cern. However, Ebola is only transmitted by patients who already present symptoms of the disease, and infec­tion only occurs upon direct contact with the blood or body fluids of an Ebola patient. Consequently, trans­mission of the outbreak can be contained through careful monitoring for fever among persons who have visit­ed, or come into contact with persons from, the site of the outbreak. Thus, patients suspected of presenting symptoms characteristic of Ebola should be quarantined. Despite ongoing efforts directed at experimental treatments and vaccine development, current medical management of EVD is largely limited to supportive therapy, thus making early case identification and immediate implementation of appropriate control measures critical. Optimization of EVD management together with rapid diagnosis, greatly improve the clinical outcome. Recent advances in diagnostic procedures and new therapies of patients with several drugs in the initial phase of treatment could further improve the prognosis of EVD cases. This review summarizes the biochemical and virological characters of Ebola virus and highlights the challenges for development of new effective antiviral drugs and vaccine for prompt control and prevention of EVD outbreaks.
