What is the main route of transmission of tuberculosis?

Tuberculosis is a chronic respiratory infection caused by lung infection. Tuberculosis is transmitted from tuberculosis patients to healthy people by talking loudly and coughing up droplets.

If you have tuberculosis, when you are treated. It is best to live in separate rooms with your family, eat separately, and separate bowls and chopsticks. Boil the dishes and chopsticks in water for 5 minutes every 10 day and disinfect them once. Try to avoid contact and stay away from children. So as not to transmit tuberculosis to children. Don't spit everywhere. Mycobacterium tuberculosis has a strong vitality and is stubborn. It can survive 1~2 hours under strong direct sunlight. It can survive in dark and humid places for several months. Mycobacterium tuberculosis in sputum can only survive for 5 minutes in boiling water. All tuberculosis patients should cover their mouths with clean handkerchiefs when coughing, and keep a distance of at least 1 m from healthy people when speaking and coughing, so as to avoid infecting others.

Mycobacterium tuberculosis mainly uses air as the infection medium, which is called droplet infection. When patients with infectious tuberculosis cough or sneeze, sputum containing Mycobacterium tuberculosis becomes droplets and spreads into the air. After normal people inhale, mycobacterium tuberculosis will have the opportunity to multiply in the lungs and infect the lungs. People who are in close contact with patients with infectious tuberculosis are the most vulnerable to infection.
