No infectiousness after six months of tuberculosis treatment does not prove a complete cure, but also needs to be combined with the condition of the lesion itself and the patient’s own physical condition, to make a comprehensive judgment. After six months of tuberculosis treatment, three consecutive sputum cultures are negative, and most of them will no longer be obviously infectious. However, if there are still obvious lesions through CT examination of the lungs, no fibrosis or calcification, and the patient still has symptoms such as low-grade fever and night sweats, the patient is still not cured, and standardized treatment under the guidance of the clinician is still needed to avoid the recurrence of the disease. During the treatment of tuberculosis, once there are obvious abnormalities in liver function and urination, it is necessary to be admitted to the hospital in time for examination and standardized treatment after diagnosis of the disease, so as to avoid the delay of the disease.
