[The basic causes of relapses in respiratory organ tuberculosis]

The authors analyze 1080 cases of recurrence of tuberculosis of the respiratory organs with emphasis of their causes. It was found that recurrences were observed in subjects over 40 years of age that were dismissed from dispensary prophylactic examination or observed in subgroup VII-A and more frequently than freshly diagnosed tuberculosis showing bacteria discharge and pulmonary destruction. It was found that the leading cause of recurrence is an inadequate course of chemotherapy.
