Zombies are famous icons in the horror genre. I don’t think
there’s anyone in the 21st century who hasn’t heard the word zombie
before. From black magic to animal diseases, there were many different causes
why this infection started, one of which was something called Kuru.
Kuru is a rare degenerative disease that has affected only,
mysteriously enough, the Fore tribe in Papua, New Guinea. According to the
article "Kuru: The Laughing Sickness- The Oddest & Rarest Infectious Disease in The World" by Francesca Fiore, the main cause of this disease, which had been thoroughly
researched by Australian doctors in 1957, was not because of the environmental
toxins nor was it hereditary. Because of the unknown causes, and also because
of the tribe’s lack of communication outside, they have thought this disease
was because of witchcraft, or a curse placed on their family.
As stated in this article by Dennis O'Neil, it was not until the
late 1950’s when American pediatrician Carleton Gajdusek came to try and solve
the problem. It was discovered through the microscopic examination of dead Kuru
victims, he discovered that the disease organism was carried through the
bloodstream and was concentrated in the brain tissue.
When you look at the microscopic view of the brain tissues
of Kuru and compare them to classic CJD (most commonly known as Creutzfeldt–Jakob
disease) and Scrapie, it was clear enough for them to conclude that Kuru is
caused by prions. And because of this, it has spread some light on what was the
cause of this incurable disease; it was the Fore tribe’s unusual funeral
ceremony: the consumption of dead relatives. Or most commonly called as cannibalism.
“They weren't, for the
most part, what we have come to think of as cannibals in Western culture. They didn't contract the disease from so-called headhunting. They became afflicted
with Kuru from their bizarre funeral customs.”
To bring out stronger evidence, those afflicted with the
disease are mostly women and children, who ate the less desirable parts of the
body which includes the brain. Another factor, as the article states, is the
women’s exposure to the deceased’s blood and tissues from food preparation,
bringing a higher risk when they’re exposed on cuts and open sores.
Today, cannibalism in New Guinea is outlawed, but there are
still those out there who are affected due to the disease’s long incubation
period, some of which lasted up to 30 years. And because of this, it is now
believed that the disease is completely extinct.
Although it is not the only culture-specific disease out
there, Kuru is a very notable disease and has been a source of inspiration in
some notable works.
