First, the cause of tuberculosis is the decline of patients' resistance, especially the infection of mycobacterium tuberculosis. Healthy people are in close contact with tuberculosis patients. Tuberculosis patients can spread tuberculosis into the air by coughing, sneezing, breathing or laughing loudly. Tuberculosis is combined with dust and droplets in the air. Healthy people inhale these droplets and deposit them in the lungs, and then tuberculosis, the so-called tuberculosis, occurs. It takes some time from infection with mycobacterium tuberculosis to tuberculosis. Whether it is tuberculosis during this period depends on the immunity of healthy people. If your immunity is low, you may become a tuberculosis patient. Generally, patients infected with tuberculosis will have symptoms such as cough, hemoptysis, hot flashes, night sweats, weight loss, diet decline, and some female patients will also have symptoms such as menstrual disorders.
Second, the treatment of pulmonary tuberculosis The treatment of active pulmonary tuberculosis includes two aspects, chemotherapy and other treatments. The principle of chemotherapy is early, regular, whole course, moderate and combined, and the whole treatment scheme is divided into two stages: strengthening and consolidating. Other treatments include symptomatic treatment, glucocorticoid and surgical treatment. Symptomatic treatment refers to proper hemostasis treatment for patients with hemoptysis; For patients with particularly serious symptoms of tuberculosis poisoning, glucocorticoid treatment is given on the basis of routine application of tuberculosis drugs; Patients with thick-walled cavity, tuberculous empyema, bronchopleural fistula and hemoptysis can be treated surgically if they are ineffective after reasonable chemical treatment.
Prevention and control of the source of tuberculosis infection. This is the most important aspect of preventing tuberculosis and controlling its spread. Generally speaking, early diagnosis and treatment are necessary for pulmonary tuberculosis patients with positive sputum examination, and timely antiviral treatment can obviously reduce infectivity. Cut off the transmission route. In other words, it is necessary to manage the sputum of patients with sputum positive pulmonary tuberculosis. The patient's sputum should not be vomited indiscriminately. When coughing or sneezing, cover your mouth and nose, disinfect sputum with 1% formaldehyde solution, and expose clothes and quilts to the sun. Protect susceptible people. Children and adults need to be vaccinated with BCG, which can play a preventive role. If children or adolescents are strongly positive in PPD test, appropriate preventive drugs can be used.
