Recurrences (reappearance of the disease) after successfully treated tuberculosis are rare. They usually occur in the first year after the end of drug therapy. A chest X-ray is usually carried out 6 and 12 months after the end of treatment to monitor the course of the disease and to detect a possible recurrence of pulmonary tuberculosis. In the case of resistant tuberculosis or difficulties during therapy, these checks are carried out over two years. In the case of extrapulmonary tuberculosis, other examination methods are used depending on the organ. If changes persist even after therapy (e.g. permanent changes in the lung tissue) or if new or recurring symptoms give cause for this, additional examinations can be carried out.
