Sad truth is that CDC/WHO are one of the most competent authorities on the matter, and they have experienced experts in the relevant fields. Only when politics comes into play, that the organisations' actions and intentions are called into question.

Of course, the chances of that happening are probably lower than an actually lethal virus leaking from a lab.
