metabolic activity, can replicate only within a cell of another host organism. A virus

consists of a core of nucleic acid, either RNA or DNA, surrounded by a coating of

antigenic protein and sometimes a lipid layer surrounds it as well. The virus provides the

genetic code for replication, and the host cell provides the necessary energy and raw

materials. There are more than 200 viruses that are know to cause disease in humans. The

Ebola virus, which dates back to 1976, has four strains each from a different geographic

area, but all give their victims the same painful, often lethal symptoms.

The Ebola virus is a member of a family of RNA viruses known as 'Filoviriade'

and falling under one genus, 'Filovirus'. "The Ebola virus and Marburg virus are the two

known members of the Filovirus family" (Journal of the American Medical Association

273: 1748). Marburg is a relative of the Ebola virus. The four strains of Ebola are Ebola

Zaire, Ebola Sudan, Ebola Reston, and Ebola Tai. Each is named after the geographical

location in which it was discovered. These filoviruses cause hemorrhagic fever, which is

days, before the cells die. The several cycles of replication occur in a primate before the

medical supplies worsen the spreading of the disease, meaning that there could be a
