In that case, what happens in Vegas will slowly spread out across the surrounding area, re-animating the dead and resulting in thousands of painful deaths. Each chomped-upon victim will eventually turn into another shambling predator, a staggering corpse with an insatiable hunger for flesh. Sure, the military will eventually show up; when they do they'll eliminate any perceived threat that stands in their way - and that includes any poor sod who's taken a bite. They might stick you in quarantine, but more likely they'll just ventilate you skull with a few bullets, then drive off in a Humvee singing Minnie Riperton's "Lovin' You," in a strangled voice."
