Patients with pulmonary tuberculosis can be completely cured, and if they are clearly diagnosed, they need to undergo systematic and standardized anti-tuberculosis treatment, and most of them can turn from infectious to non-infectious after about 15 days of anti-tuberculosis treatment. During the course of anti-tuberculosis treatment, it is necessary to enhance nutrition, get good rest, and have regular follow-up examinations. Most patients with tuberculosis are not infectious after being discharged from the hospital, but if they are, they cannot be discharged from the hospital and still need to be isolated.
