Sorry, I should have been clearer. I've only seen the trailer. But then, there's the question of, if it is airborn and affects all apes... why not Humans too? 1) We are apes. 2) The trailer makes it clear that it was made with Humans in mind.Did you bother to stick around and watch the post-credits scene? The movie kind of explains what happens.
(In the original origin it was made clear that the apes had replaced dogs and cats as pets, then became menial workers, so there were a lot more of them then there are today.)
