101 cases of recurrent tuberculosis were analyzed. Late relapses were more common (69.3%). Among the clinical forms, infiltrative pulmonary tuberculosis dominated (59.4%). Decay was detected in 69.3%, bacillic excretion - in 74.2%. Drug resistance of mycobacterium tuberculosis was found in 31.1% of patients, and in relation to those who had taken antibacterial drugs in the past, in 43.2%. In the development of relapses, the main role was played by not entirely satisfactory working and living conditions, alcohol abuse and its consequences, inadequate primary treatment, and concomitant diseases.
