Tuberculosis in the chest alone is not contagious, but if there is a combination of pulmonary tuberculosis, especially sputum-positive patients, or open sinus tracts in the chest wall, there will also be recurrent purulent discharge, which is also contagious; bronchopleural fistulas found by fiberoptic bronchoscopy are open tuberculosis, which is also contagious. Many patients have obvious symptoms of tuberculosis poisoning, including loss of appetite, emaciation, afternoon fever, weakness, night sweats, etc.; appropriate physical exercise is needed to enhance physical fitness, which can improve resistance to the disease, and surgery is needed to further drain the abscess chest after severe infection.
