Ebola and Marburg haemorrhagic fevers are caused by the Ebola and Marburg virus respectively, both belonging to the same virus family. Both are rare diseases, but have the potential to cause high death rates. Transmission of the viruses occurs from person to person through close contact with blood or body fluids.
Clinical illness starts as a flu-like syndrome, rapidly evolving to severe disease with bleedings. No treatment or vaccine is available for either disease.
