Tuberculosis, especially pulmonary tuberculosis, is a Class B infectious disease in China and is mainly transmitted through the respiratory tract, so it is not transmitted through blood. Patients with tuberculosis who have a large amount of bacilli may cough or sneeze, and a large amount of mycobacterium tuberculosis may be discharged into the air with the discharge of saliva. If you do not pay attention to this and inhale air with tuberculosis bacilli, there is a risk that a healthy adult may be infected. Therefore, the management of tuberculosis patients requires air and droplet isolation, centralized collection of sputum and soaking in disinfectant before pouring down the drain, and ventilation of the patient’s room, all of which can reduce the risk of infection to other people.
