A total of 20,656 cases of EVD have been reported, the report released Monday said. The data refer to Guinea, Liberia and Sierra Leone.
According to the statistics, the maximum number of Ebola-related deaths and cases has been registered in Liberia -- 3,471 cumulative deaths and 8,018 cumulative cases. Liberia is followed by Sierra Leone (2,915 deaths and 9,772 cases) and Guinea (1,767 and 2,769) respectively.
Separate cases have also been registered in Mali, Nigeria, Senegal, Spain, Britain and the US.
EVD, previously known as the Ebola hemorrhagic fever, is a severe illness in humans, often fatal. The virus is passed on to people from wild animals and can be transmitted from humans to humans. The average EVD case death rate is some 50 percent.
The first outbreaks of the EVD occurred in remote Central African villages, near tropical rainforests. However, the most recent outbreak in western Africa involved major urban and rural areas.
Early supportive care, which includes rehydration and symptomatic treatment, improves the survival rate.
No licensed treatment has yet been proven to be able to neutralise the virus but a number of blood, immunological and drug medications are under development. There are no licensed Ebola vaccines yet but two candidates are being evaluated.
