If by "significantly" you mean, "by a week or so", then yeah. Otherwise, these guys decay pretty swell. After only a rough month:But yeah, in the real world, even the Walking Dead's... sexy virus'd up zombies wouldn't work too well.
However, the whole 'uber-rabies' take on a zombie scourge is much more realistic as far as RL is concerned. Carriers would act completely animalistic/berserker and try to attack anyone in their vicinity, the CNS(central nervous system) becomes depressed which systemically dampens the response to pain, the rabies virus can be spread through bites, etc. etc.
However, even people with rabies could still be killed as easily as an average joe.
