Before the disease was registered, the first detected patients who died from tuberculosis had not generally turned for medical aid or had turned 3 months or more after the occurrence of significant clinical signs. Before their death from tuberculosis, the contingents of tuberculosis-controlling services of municipal entities were discharged from hospital many times for violation of the inpatient routine; subsequently they did not come to a tuberculosis dispensary and refused to be treated in the outpatient setting. Primary drug resistance, allergic reactions, and intolerability of antituberculous drugs did not play a significant role in the occurrence of death. The patients are themselves guilty in the development of secondary resistance to some drugs.
