Fruit bat caves are piled high with their feces. A perfect Ebola breeding ground and place for it to mutate into worse forms of Ebola
The problem is not one of fruit bats living too close to humans, but rather humans eating fruit bats and most anything else in what they call “bushmeat”
From what I have been told bushmeat is either only partially cooked or uncooked and then allowed to spoil before consuming, for the “flavor”. (Western pipeline workers tell stories about the awful smell of the native laborers gleefully lunching on bushmeat)
West Africa is loaded with humans that act primitive and seem to have little concern with food safety. Add on the warm humid climate and its like they are living in a lab experiment, that sometimes goes bad.
