Tuberculosis can relapse, and the answer is definitely yes. In clinical practice, we see many patients who have had tuberculosis and, years later, experience a recurrence of the disease, even multiple recurrences. However, the probability of this is generally not high. As long as everyone follows the doctor's instructions for standard anti-tuberculosis treatment and completes the full course of treatment, most patients can be cured. However, there are a few people whose treatment process is not standard, or who stop taking their medication on their own, and these actions can increase the risk of tuberculosis recurrence.
