In fact, 75% of newly emerging diseases are zoonotic. I have divided the process of disease emergence into two steps, for analysis: (1) what I call introduction, where these "Andromeda-like" infections are coming from; and (2) establishment and dissemination, which (fortunately for us) is much harder for most of these agents to achieve.The basic lesson there is that many may be called, but few are chosen.
