At its peak in the 1950s and ’60s, the kuru epidemic nearly decimated the Indigenous Fore people of Papua New Guinea.
Until the 1930s , no outsiders have a go at it that the Fore mass of Papua New Guinea even survive . In one of the world ’s least - explored regions , the Fore had lived independently for year , developing a distinctive culture with traditions unknown even to their fellow islanders . One of these traditions was ritual cannibalism , which led to a widespread disease visit kuru .
Australian atomic number 79 prospectors were the first outsiders to make contact with the autochthonous people who lived in the easterly highlands of Papua New Guinea . The gold prospectors were soon follow by researchers and officeholder who patrolled the sphere . But it would take more than 20 age for the Fore ’s cannibalism to descend to Light Within , along with its horrific outcome .
To the Fore , cannibalism was meant to be an act of love and grief — because they ate the bodies of their dead loved ones . But despite their intentions , this rite was viewed with horror by most other groups of people around the populace . And the consequence of this practice was just as dreadful .

The Fore ’s consumption of numb citizenry directly led to the spread of kuru . Also known as the “ laughing death , ” kuru is a fatal brain disease that cause victims to fall behind control of their emotion , limbs , and bodily function . Disturbingly , many dupe hurt from uncorrectable fits of laughter — and die less than a yr after first demo symptom of the disease .
At its peak in the 1950s , kuru was wiping out two percent of the federation of tribes per class . While both the Fore and outside researchers realized that there was a major trouble , they had no approximation what was causing the laughing demise epidemic at first . But before long , everyone learned the dreadful truth .
Inside The Origins Of The Kuru Disease

Papua New Guinea is illustrious for its hundreds of Indigenous group left unaffected by remote civilizations for thousands of years . In their home nestled among the obtuse wood that blanket the nation ’s mountains , these radical build up a classifiable range of civilization and practices .
It was n’t until the 16th century that Lusitanian and Spanish explorers first touch down on the realm . And even then , they only made contact with those who were living on the coasts . So , many Indigenous group remained uncontacted by people from other countries until well into the 20th one C .

Some of the more distant groups — like the Fore — practice cannibalism . Though each tribe approached the ritual differently , the Fore firmlybelievedthat it was a consecrated funerary ritual . So , every prison term a person died , their torso was fake and eaten by their loved 1 . The Fore people thought this ritual would tame the purport of the stagnant body , and honor the deceased .
One medical researcher explained the Fore philosophy as such : “ If the body was buried it was eaten by worms ; if it was placed on a weapons platform it was eaten by maggots ; the Fore believed it was much better that the body was eaten by mass who love the deceased than by insect and louse . ”

It was usually women who were tasked with eating the person ’s body — because it was thought that their bodies could do by housing a “ dangerous ” spirit . They would eat nearly every piece of “ essence ” and Hammond organ in the body except for the gall bladder . Crucially , this included the brain . However , women would sometimes feed “ bite ” from the corpses to their youthful kid . So , it was mostly women and children who were affected by kuru .
Though missionaries and compound officials condemn cannibalism among the tribe who practiced it , the rite remained far-flung among groups of Fore . It ’s unknown exactly when the kuru disease first appeared among them . But some researchers believe it first arose around the 1910s or 1920s , just a few tenner before they made touch with outsiders .
This is back by the lack of mention of the disease in Fore histories , and because the Fore themselves recognise that the disease was deplete their universe . If they had know with kuru for generations , there would have likely been no Fore left . But by the prison term they meet Australian and American researchers in the 1950s , they still add up up to 11,000 people .

The trouble facing both the Fore and researcher was that no one knew what kuru was or how it spread . But they did be intimate the laughing demise had become an epidemic , kill up to 200 the great unwashed per year . While investigator thought contaminants or genetics may have caused the disease , the Fore people thought it was men who were practicing “ sorcery . ” But it was n’t until the other sixties that researchers were finally able-bodied to figure it out .
How Ritual Cannibalism Caused The Laughing Death Epidemic

Anthropologist Shirley Lindenbaum and her then - married man Robert Glasse were among the scientists involved in the first consecrated cogitation of kuru in 1961 . Traveling from village to village in the Fore community , they analyse potential causes of the disease . After ruling out contamination , they soon realize the disease was n’t genetic either , because it affected women and children in the same societal groups , rather than the same genetic radical .
But then , during their second sojourn , a New Zealand neurologist and epidemiologist named Dr. R.W. Hornbrookposed a key inquiry : “ What is it that the grownup women and the children of both sexes in the Fore tribe are doing that the adult Man are not ? ” The answer before long became decipherable : They were practicing cannibalism on their dead loved ones at funerals .
Wikimedia CommonsThe Fore people, like other Indigenous tribes in Papua New Guinea who once practiced cannibalism, are still around today and have since recovered from the kuru epidemic.
Though some experts remained questioning , Lindenbaum and her colleagues persisted , last instigate a grouping at the U.S. National Institutes of Health to test their theory . The researchers inject samples of infected human brains into chimpanzees . When the chimpanzees begin to present sign of kuru calendar month later , Lindenbaum ’s guess was vindicate .
But even though the central interrogative of what caused kuru had been answer , there were still some hole to fill in . After all , the Fore were far from the only group to ever practice cannibalism throughout history , but they were the first sleep with to go through such a disease . So , what precisely had sparked this unusual malady among the Fore but not other kindred ?

Since the Fore had mostly stopped practicing cannibalism by the sixties — peculiarly when they learned the desperate consequences — it was elusive to say incisively what had caused the laugh decease epidemic . However , many experts believe it started after one Fore person develop a neurological condition prognosticate Creutzfeldt - Jakob Disease , which is interchangeable to kuru .
Both illnesses arecaused by prion , which are abnormal proteins that fold in an strange way , work lesion in the encephalon and causing unfathomed damage to the aflutter system of rules and eventually the sleep of the consistence . Both disease are also calamitous and often cause demise about a yr after symptoms first come forth .
Researchers have theorized that the member of the Fore who developed Creutzfeldt - Jakob Disease had die sometime before the 1910s or 1920s . When this mortal ’s consistency was consume , the prions in their brain tissue paper spread to those who ’d eaten them , who in turning passed the disease on to those who eat them . Without the welfare of innovative medicament , the Fore were left with no cue as to what was killing hundreds of them for decade .
petty did they know that it was their ritual expenditure of brain .
When The Kuru Epidemic Finally Ended
Wikimedia CommonsThe Fore people , like other autochthonic tribes in Papua New Guinea who once practiced cannibalism , are still around today and have since recovered from the kuru epidemic .
The number of kuru cases among the Fore gradually dwindled over the years after the researchers ’ discoveries . However , the cases did n’t disappear immediately , as the disease sometimes took decades to show its effects .
According to Michael Alpers , a medical researcher at Curtin University in Australia who study the disease , the last kuru victim decease in 2009 . And the epidemic was formally adjudge over among the Fore people in 2012 .
Today , the Fore number about 20,000 multitude — which is nearly double the number of masses who were around during the height of the kuru epidemic . The Fore are thrilled with their population growing , specially since the number of woman and children is in a steady place once again .
As for the researchers , those who worked on the chimpanzee experiment were award a Nobel Prize for their finding . The knowledge gained from the research led to further discovery in understanding malady such as Creutzfeldt - Jakob Disease , bovine spongiform encephalopathy ( or “ delirious moo-cow disease ” ) , and neurodegenerative diseases like Alzheimer ’s .
Most of late , researchers happen that even though the Fore ’s retiring impost of funerary cannibalism led to tragedy , it also result in a unique adaptation . In 2015 , expertsdiscoveredthat some Fore had developed a factor that protects them from kuru as well as other prion disease like mad cow . And it may even protect them from some forms of dementia .
While they ’re unbelievable to come back to the ghastly customs of their ascendant , today ’s Fore can be thankful that the unintended consequence of a long - held rite now offers a positive trait that may hold the samara to defeating some of humanity ’s most enfeeble neural conditions .
