People of a remote village of Kalachi, in northern Kazakhstan, is suffering from a mysterious illness that makes them sleep for days at a time.
According to a report in ‘Mirror’, doctors refer to the illness as ‘encephalopathy of unknown etiology’, or a brain disorder with no known origin.
About 100 of Kalachi's total 680 residents have been affected by the illness. They fall asleep at random, usually for days at a time, and then suffer from hallucinations and memory loss upon waking, according to Kazakh media reports.
Even as medics are yet to ascertain the causes, villagers believe in mass psychosis, poisoning, insect bites, and even an alien invasion.
Kazakh Health Ministry recently said it could be possibly because of ‘vapours’ that build up during the heating season in poorly ventilated houses, reported Diapazon.kz.
While tests are still being conducted to rule out any possible radiation from a Soviet-era uranium mine in the area.
