This is true, however it does not answer the question originally posed.  WHY
American troops, and not just because the people avoid the infected person
(which, incidentally, they do not do nearly enough - I recall that a good
many of the people who died last time were caring for sick people and caught
the virus).

In this time of mass migration, movement of hundreds and thousands of people
through the forest, where it is presumed a natural vector would live, why
are we not seeing anyone in Zaire with ebola?  It is a very interesting
question, and I sincerely hope we are not answered with an outbreak.  The
people there are having a hard enough time without Ebola.  But the question
remains, why are we not having an outbreak, and where is the virus hiding.
The people in the forests of Zaire right now are probably hungry, and eating
anything that they can - something there must carry ebola.  How much longer
can this crisis go on before we do get an outbreak?  And this time, it is
not likely to be so easily contained, with people moving rapidly, and a war
going on.  There are few services in place that are capable of containing it
if it does show.

Any ideas why we havent seen it?  any thoughts as to when we might?
