The Ebola virus is highly contagious and causes a range of symptoms including fever, vomiting, diarrhea, generalized pain or malaise and in many cases internal and external bleeding.
Mortality rates of Ebola fever, according to the World Health Organization, are extremely high, with the human case fatality rate ranging from 50 percent to 89 percent, depending on viral subtype.
According to the World Health Organization, Marburg is a severe and highly fatal disease caused by a virus from the same family as the one that causes Ebola hemorrhagic fever.
