Since March 2013, the mysterious illness has affected more than 140 people in Kalachi and Krasnogorsk, dusty settlements in the huge Kazakh steppe, with a total population of 810 people, mostly ethnic Russians and Germans. Villagers would fall asleep suddenly, even while walking, and wake up with memory loss, grogginess, weakness, and headaches. Some fell victim more than half a dozen times, with sufferers sleeping for up to six days at a time.
“The sick person appears to be conscious and can even walk. But all the same, he then falls into a deep sleep and snores, and when they wake him up … the person remembers absolutely nothing,” the newspaper Komsomolskaya Pravda reported after a 2014 investigation.
The sickness would affect both old and young, with children dropping off at school. Some reported nightmarish hallucinations: local children Rudolf Boyarinos and Misha Plyukhin told Komsomolskaya Pravda they had seen winged horses, snakes in their beds and worms eating their hands.
Even pets were not immune. Kalachi resident Yelena Zhavoronkova told the newspaper Vremya that her cat Marquis suddenly “went stupid” on a Friday night and began meowing and attacking walls, furniture, and the family dog.
“He fell asleep toward morning and snored like a human until lunchtime on Saturday. He didn’t react to anything, not even cat food,” Zhavoronkova said.
Many suspected the nearby uranium mines that were closed after the fall of the Soviet Union, leaving Krasnogorsk a ghost town with only 130 of its former 6,500 residents. Kazakhstan’s health ministry tested more than 7,000 nearby homes but didn’t find significantly high levels of radiation or of heavy metals and their salts. It detected raised radium levels in some homes, but it was not enough to explain the phenomenon.
Now the mystery has at last been solved and the cause does indeed lie in the uranium mines, said Kazakhstan’s deputy PM, Berdibek Saparbaev. After analyzing
the results of medical examinations of all the residents, researchers concluded that it was caused by heightened levels of carbon monoxide and hydrocarbons in the air.
“The uranium mines were closed at some point, and at times a concentration of carbon monoxide occurs there,” Saparbaev said. “The oxygen in the air is reduced accordingly, which is the real reason for the sleeping sickness in these villages.”
Evacuation of the two villages has begun, with authorities reportedly relocating 68 of 223 families so far.
