Drug-resistant tuberculosis is a chronic infectious disease transmitted through the respiratory tract, and its prevention methods are as follows: 1. Control the source of infection: clinically, early detection, early diagnosis and early treatment should be achieved, and patients should be supervised to take medication regularly and be reviewed regularly to reduce infectiousness; 2. Patients with tuberculosis should not laugh or talk loudly to others, and cover their mouth and nose when sneezing. Do not spit anywhere when you have sputum, but spit into a sputum cup with a lid containing disinfectant solution; 3. Protect susceptible people: enhance exercise and improve your immunity. For newborns, BCG vaccination is clinically recommended for prevention, and for susceptible patients, preventive anti-tuberculosis treatment is recommended.
