A history of kuru.
Kuru is placed in its geographic and linguistic setting in the Eastern Highlands of Papua New Guinea. The epidemic of kuru has declined over the period 1957 to 2005 from more than 200 deaths a year to 1 or none. Since transmission of the kuru prion agent through the mortuary practice of transumption ceased by the early 1960s, the continuation of the epidemic into the present century demonstrates the long incubation periods that are possible in human prion diseases. Several histories of kuru are portrayed, from the different perspectives of the Fore people, of the scientists striving to elucidate the disease, of those engaged in research on prions, and of humans confronting the implications of kuru-like epidemics in the remote past. Kuru has connections to bovine spongiform encephalopathy through intraspecies recycling. The influence of host genetics on the incubation period in kuru may help to predict the shape of the still ongoing epidemic of variant Creutzfeldt-Jakob disease.
