Tuberculosis is a chronic respiratory infectious disease. There are three conditions for the onset of infectious diseases, one is the source of infection, one is the route of transmission, and the third is the population with hepatitis B. The source of infection of pulmonary tuberculosis is the patient who has discharged bacteria or is in the period of infection. The second is the way of transmission. Tuberculosis is transmitted through the respiratory tract, so it is possible for tuberculosis patients to talk loudly, cough, sneeze and laugh, which may expel particles containing tuberculosis bacteria out of the air. The third is the population of hepatitis B. Because of the long-term use of hormone, these patients have low resistance, and some people are malnourished. These are some people with hepatitis B. If these three conditions are more consistent, it may cause tuberculosis. If you are not a hepatitis B population, you have strong resistance, and infectious TB bacteria may not necessarily come on.
