We’ve already discussed the possibility that zombie blood may flow through the body on its own (see: Zombie Blood Flow: Self Propulsion). Now ZRS Researcher, Alex Tavelo, offers further evidence to support this theory.
Tavelo suggests that zombified blood must be able to circulate without being forcibly pumped by a beating heart, or else zombies wouldn’t be able to spread their infection successfully. Her argument hinges on the notion that all communicable illnesses take time to fully overcome their host’s defenses (see: Zombie Incubation Period). Blood borne illnesses travel through the human body by catching a free ride on our fast-moving highway of arteries and veins, but after death the highway grinds to a sudden halt.
“If zombie blood doesn’t flow on it’s own, then the infection would stop advancing at the moment a person dies. In the case of a quick death, the tainted blood wouldn’t have time to reach the brain or central nervous system, so that newly dead person would therefore not become a zombie.”
Following this logic, if zombified blood is not able to flow at will, then a person who is bitten on the hand and then soon after fatally shot through the chest would likely not become a zombie even though the brain was never destroyed. As long as death occurs before the zombie infection has fully taken route, then another member of the undead legion would not be created.
Tavelo’s theory could have a far-reaching impact on how we gauge the infectiousness of the zombie plague, and where we focus future survival efforts. More research is required.
