Bronchial tuberculosis generally requires 6 months of treatment to be free of contagion, but the exact use needs to be determined in consultation with a physician. According to the general treatment cycle of tuberculosis diseases, bronchial tuberculosis also requires 6 months of full and regular treatment to be fully controlled. At this time, the tuberculosis bacillus in the body has been killed, inactivated, and the infectiousness will disappear. However, due to factors such as the start of treatment, differences in personal constitution and viral load, the treatment cycle is not fixed for all people. Some people may be cured in less than 6 months, but some people with poorer immunity may need a longer period of time. The exact situation needs to be determined in time by consulting the attending physician.
