Ebola
This virus is one of the most lethal and horrific viruses known to civilization. Ebola hemorrhagic fever is severe, often fatal and it affects monkeys, apes and humans. The Ebola virus is a member of a family of RNA viruses known as filovirus (genus Filoviridae). When magnified by an electron microscope, these viruses have the appearance of long string-shape, with little hook or loop at one end. There have been four identified strains of Ebola. Three of the four species of Ebola viruses identified so far have caused disease in humans. Ebola-Zaire was discovered in 1976 and was name after a river in Zaire, Africa, where it was first encountered. Ebola Sudan was discovered in Western Sudan in 1976. Ebola Tai is the most recently discovered type of Ebola virus. It was discovered in 1995 on the Ivory Coast of West Africa in the Tai forest. A Swiss researcher was the first infected human but survived the infection. Ebola Reston, a variation of Ebola virus discovered in the African monkeys imported to the United States, is not believed to cause health problems in humans but does cause affliction in monkeys.
