In the Novels is the rest of the world ever mentioned? or is the outbreak limited to USA?
Ive read most of the comics and the novel, so far as I know
I'm not current with the comics at this point, but the way it and the tv show are presented, is that Rick and his rag-tag band exist in this microcosm within the state of Georgia.. All hell has broken loose there and they are just making it day to day... Because there's no power, there's no real way to know exactly what's going on outside their part of the world. Seattle or even Albuquerque could be a safe haven (having battled all those zombies from Santa Fe), but there's just no way for them to know.
In World War Z, the common practice was for civilization to head north to the upper reaches of Canada, since the zombies couldn't traverse in the sustained freezing cold.. Obviously, there's not much of a chance of that happening in Georgia.
