Many prisoners suffer from hepatitis, tuberculosis, leprosy and psychiatric diseases due to beatings, poor sanitary conditions, poor diet and degrading treatment. The sick prisoners are quarantined and squeezed into small huts in the mountain. For example, there are two such huts in Settlement No. 22 accommodating some 100 patients. No medical treatment is provided. They are simply lift there to die. They do not work, but few ever leave the place alive.
