The 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

in the genital secretions for a brief
period after. This makes it possible for the virus to be spread by sexual
contact. Complete recovery is reached only when no particles of the virus
are left in the body fluids, this however is rarely attained. The disease,
for humans, is not airborne, capable to be passed on through air travel,
but for nonhuman primates it has been a possibility in a few cases.
Ebola Zaire was identified in 1976 in Northern Zaire and was the
