[Incidence and duration of recurrence of respiratory tuberculosis in adults].

The relapse-free interval after the primary treatment has been studied in 1165 adults with respiratory tuberculosis (RT) who has developed the recurrent disease. Early recurrences (in follow-up group III) were recorded within 2-3 years since the treatment completion. Late recurrences occurred in group VII-A 9.7 years, in patients crossed off the register 13.1 years after the treatment. New principles of antituberculosis service at specialized dispensaries proposed by the authors promote more efficient regimens of treatment, more rapid cure. It secures a stable rate of recurrences which does not exceed 1.2% from those treated.
