Ebola Virus
A virus is an ultramicroscopic infectious organism that, having no independent 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. ... 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. ... These filoviruses cause hemorrhagic fever, which is actually what kill victims of the Ebola virus. ... The
incubation period for Ebola Hemorrhagic Fever ranges from 2-21 days (JAMA 2! ... The blood fails to clot and patients may bleed from injections sites and into the gastrointestinal tract, skin
and internal organs (Ebola Info. ... The Ebola virus has a tropism for liver cells and macrophages,
macrophages are cells that engulf bacteria and help the body defend against disease. Massive destruction of the liver
is a hallmark feature of Ebola virus infection. This virus does in ten days what it takes AIDS ten years to do. ... HIV the virus that causes AIDS
requires only a biosaftey level of two. ...
Ebola can be spread in a number of ways, and replication of the virus occurs at an alarming rate. Ebola replication in
infected cells takes about eight hours. Hundreds to thousands of new virus particles are then released during periods
of a few hours to a few days, before the cells die.
