The story of kuru is a classic one in anthropology and medicine. Called the "laughing death" in the Australian newspapers, the disease swept over the Fore population of Papua New Guinea's eastern highlands over the course of the 20th century, peaking in the late '50s and early '60s.
Victims experienced body aches and instability at first. They'd become emotionally labile, trembling and laughing involuntarily. Gradually, they lost control of bodily functions and the ability to swallow or stand. Their bodies wasted away, immobile until death, which could occur anytime between six months to a year after the onset of symptoms.
For decades, scientists were stumped as to how it spread. The usual signs of an infectious agent were not apparent, yet people were dying by the hundreds every year. The disease struck mostly adult women and young children. Women died of kuru at approximately three times the rate of men, leaving hamlets bereft of mothers and wives. It was a "demographic emergency," explains anthropologist Shirley Lindenbaum, who began research among the South Fore people at the height of the kuru epidemic in the early 1960s. As she describes in her 1979 book, Kuru Sorcery: Disease and Danger in the New Guinea Highlands, the Fore blamed the deaths on malevolent sorcery. They believed sorcerers were pushing them toward the brink of extinction.
I have been writing here about the anthropology of zoonosis, disease that spills over from animal to human. Zoonotic diseases interest me in part because they trouble our sense of species boundaries, or reproductive and even immunological divides. The lines of class difference (Mammalia, I mean) sometimes seem thinly sketched.
Kuru was not zoonotic–-quite the opposite. It was a disease borne of cannibalism.
