The primary mode of transmission for pulmonary tuberculosis

The primary transmission route of pulmonary tuberculosis is through the respiratory tract.

When a person with pulmonary tuberculosis coughs, sneezes, speaks, or laughs, they release droplets containing Mycobacterium tuberculosis into the air. These droplets can be inhaled by others, and individuals with weakened immune systems may consequently become infected with pulmonary tuberculosis. Additionally, although less common, pulmonary tuberculosis can also be transmitted via the digestive tract, such as through sharing eating utensils with a person who has pulmonary tuberculosis or consuming food contaminated with Mycobacterium tuberculosis. In some special circumstances, such as mother-to-child transmission or through skin wounds coming into contact with the bacteria, there is also a risk of infection.

Due to the high transmissibility of tuberculosis, the large number of susceptible individuals, the prolonged treatment duration, and the relatively high recurrence rate, prevention becomes particularly important. The main measures for preventing pulmonary tuberculosis include:

1. Interrupting transmission routes, such as wearing masks, ensuring indoor ventilation, and avoiding close contact with individuals who have pulmonary tuberculosis;

2. Enhancing personal immunity, such as engaging in regular physical exercise and maintaining healthy lifestyle habits;

3. And actively controlling sources of infection, such as ensuring that patients with pulmonary tuberculosis follow medical advice for treatment and avoiding crowded public places to reduce the risk of transmission.
