Asymptomatic performance of tuberculosis may be in the early stage of tuberculosis infection or during the treatment of tuberculosis. 1. Early stage of tuberculosis infection: In the early stage of tuberculosis infection, some patients may have no obvious symptoms, and when the condition of tuberculosis further develops, hemoptysis, cough, hot flashes, night sweats and other symptoms may gradually appear, and some patients may recover on their own, with no manifestation of the disease throughout the whole period. 2. During the treatment of tuberculosis: During the treatment of tuberculosis, although the disease has not been completely cured, the patient may have no obvious symptoms due to the gradual improvement of the disease. However, it should be noted that although there are no obvious symptoms, anti-tuberculosis treatment must reach a sufficient course of treatment in order to be completely cured, and the medication should not be stopped arbitrarily. It is recommended that people with tuberculosis should consult a doctor in time.
