[Ebola: the unexpected emerging disease]

In one year, Ebola virus disease has already been responsible of around 10000 deaths. 24 patients have been medically evacuated in different University Hospitals in Europe or in the United States. One medical doctor, infected during a humanitarian mission in the field has been treated in Geneva at the end of 2014. This review aims to summarize the epidemiology of the current outbreak, to describe the main virological and clinical characteristics of Ebola virus disease, and to address the most important experimental treatments available. Although the number of cases has fallen the last two months, the outbreak is not over. A safe and proctective vaccine is still needed in the race to fight this emerging viral disease.
