Since last January, the West Africa is affected by unprecedented epidemic of Ebola virus. Since then, 932 deaths were reported for 1,711 cases in four countries ( Guinea , Sierra Leone , Liberia and Nigeria ).

The Ebola virus is one of the most infectious and deadly to humans, according to the World Health Organization (WHO). This virus can cause severe disease outbreaks. It causes hemorrhagic fever which is one of the most virulent viral diseases known to man.
