A series of outbreaks of Ebola virus infection in central Africa appears
to be the result of separate introductions of the pathogen from different
animal sources involving several different viral strains, according to a study
by researchers from the Institute of Research and Development in Franceville,
Gabon, and other institutions (Science. 2004;303:387-390).
The findings suggest that the human outbreaks were touched off when hunters
handled corpses of infected animals.
