Ebola: still no known cure

There is no known cure for Ebola, although infected patients have been known to recover from the disease. Health practitioners usually isolate suspected victims in order to contain the spread and encourage prevention measures, such as regular hand-washing with soap and water. There is, however, a recently released vaccine currently being rolled out in affected areas of Africa.

The disease was first discovered in 1976 when two separate outbreaks were recorded in former Zaire, close to the Ebola River. It originates from the consumption of fruit bat, a delicacy in parts of West Africa.

The virus has claimed the lives of at least 1,200 people since its first recording. Symptoms include vomiting, diarrhea and external bleeding.
