On the other hand, Ebola's animal reservoir remains uncertain. The implication of the question is that all animal reservoirs are easily and quickly discovered, but just because that's true for some examples doesn't mean its universally true, and doesn't mean that lack of a known animal reservoir is strong evidence against the existence of one.
