This could well turn out to be true but other human cases have had 
(apparently) nothing to do with monkeys or chimps.  In any case, though 
Red Colobus monkeys are a major prey of chimps, it is still not the only 
prey.  Chimps have been known to bring down small deer and related 
animals too.  Considering the rarity of Ebola infections, I would also 
tend to think that it might be linked, following your logic, to a 
relatively rare prey of the chimps.  They occassionally kill prey X and 
prey X is sometimes infected with Ebola.
