The word Zombie is derived from the melange of the words zonbi Haitian Creole and nzumbe from the African dialect North Mbundu. Zombies are the walking dead. They have been featured horror movies since their black-and-white introduction in George Romero's 1968 epic film NIGHT OF THE LIVING DEAD. Scientists and anthropologists have searched Haiti for zombies since the 1930s without having substantiated the rumors of voodoo priests seizing the astral or soul of their victims.
According to Wikipedia Wade Davis, a Harvard ethnobotanist, presented a pharmacological case for zombies in two books, The Serpent and the Rainbow (1985) and Passage of Darkness: The Ethnobiology of the Haitian Zombie (1988). Davis traveled to Haiti in 1982 and, as a result of his investigations, claimed that a living person can be turned into a zombie by two special powders being entered into the blood stream (usually via a wound). The first, coup de poudre (French: 'powder strike'), includes tetrodotoxin (TTX), a powerful and frequently fatal neurotoxin found in the flesh of the pufferfish (order Tetraodontidae). The second powder consists of dissociative drugs such as datura. Together, these powders were said to induce a death-like state.
The Living Dead are creatures of legend, but several years ago year the Washington area had been pestered by zombie flies who have been infected by an unknown fungus taking control of their brain. Scientists have conjectured that humans might be susceptible to such an affliction and Homeland Security has studied various strategies to handle a zombie outbreak.
As far-fetched as this plague of zombies might seem there are actually five ways of humans contracting zombieitis according to cracked.com
Brain Parasites such as toxoplasmosa are weak, but in the hands of the Pentagon the fungus could be strengthened to affect humans very fast and there's nothing scarier than fast zombies a la RESIDENT EVIL. Voodoo poisons are another vector danger, but in a trance zombies are slow-moving i.e. not as dangerous as fast zombies. Viruses such as Mad Cow's Disease are a potential threat to humanity, but the living dead would be spastic and easy to avoid, unless they had numbers and in every zombie movie zombies seem to be everywhere. GM stem cell research could produce suspended dead to await a cure for their disease, but zombies are not sleeping beauties to be awaken by a kiss. Lastly nanobots seeping into your brain to take over your 'free will' and some madman hits the kill button.
