In 2009, Philip Munz and co-authors published a
paper on the epidemiology of zombie attacks:
"When Zombies Attack!: Mathematical Modelling of an Outbreak of Zombie Infection," by Philip Munz, Ioan Hudea, Joe Imad, Robert J. Smith. In:
Infectious Disease Modelling Research Progress, Editors: J.M. Tchuenche and C. Chiyaka, 2009, Nova Science Publishers, Inc., pp. 133-150 (Chapter 4).
They concluded that:
An outbreak of zombies infecting humans is likely to be disastrous, unless extremely aggressive tactics are employed against the undead. While aggressive quarantine may eradicate the infection, this is unlikely to happen in practice. A cure would only result in some humans surviving the outbreak, although they will still coexist with zombies. Only sufficiently frequent attacks, with increasing force, will result in eradication, assuming the available resources can be mustered in time.
Of course, when it comes to whether zombie attacks might actually happen, the paper does beg the question; but it's good science.

It's worth noting, though, that it applies only to an attack by, er,
real zombies, while the codespeak use of the term is a
real problem, as Tom Servo points out.
When applied to groups of people, the main function of terms like "zombie," "predator," "drone," and the like isn't to be politically correct; it's to dehumanize the reference group, which makes it a lot easier to regard them as alien or other: as legitimate targets.
Great, now I have to stock up on bacon and bullets.
