What is Ebola?

Ebola, also known as Ebola virus disease, is a severe and often deadly infection caused by viruses in the genus Orthoebolavirus, part of the family Filoviridae. It can cause fever, fatigue, vomiting, diarrhea, organ damage, and, in severe cases, internal and external bleeding. Since its discovery in 1976 near the Ebola River in what is now the Democratic Republic of the Congo, Ebola has caused multiple outbreaks in Africa and remains a major public health concern because of its high fatality rate and potential for rapid transmission.
