What is secondary tuberculosis

summary

Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis, of which the most common is pulmonary tuberculosis with pulmonary involvement. The main source of infection is patients with bacterial excretion. TB patients cough, sneeze and send out bacteria carrying droplets. If inhaled by human beings, TB will invade the respiratory tract and be engulfed by alveolar macrophages, so it will be infected. The patient will cough, lose weight, low fever, sepsis and so on. BCG should be inoculated to prevent infection. In terms of medication, we can use the method of bolus, two-stage medication, sequential therapy, intermittent therapy and so on. What is secondary tuberculosis tell us.

What is secondary tuberculosis

First: high infection rate: the annual infection rate of Mycobacterium tuberculosis is 0.72%, about 550 million people in the world have been infected by Mycobacterium tuberculosis.

Second, the main source of infection is secondary tuberculosis. By coughing, sneezing, laughing, loud conversation and other means, the micro droplets containing Mycobacterium tuberculosis are discharged into the air and spread. Droplet transmission is the most important route of transmission of tuberculosis.

Third: biological characteristics of Mycobacterium tuberculosis: 1. Pleomorphism 2. Acid resistance 3. Slow growth 4. Strong resistance 5. Complex cell structure.

matters needing attention

We should pay attention to tuberculosis, early detection, early treatment.
