How can tuberculosis (TB) be transmitted?

Tuberculosis (TB) is primarily transmitted through airborne particles when an infected person coughs, sneezes, talks, or sings. The bacteria responsible for TB, known as Mycobacterium tuberculosis, become aerosolized and can remain suspended in the air for a period of time. When someone inhales these droplets, they can become infected with the bacteria. This mode of transmission highlights the importance of respiratory hygiene and protective measures in healthcare settings and other environments where TB exposure may occur.

While sharing food, skin contact, and touching contaminated surfaces may pose risks for other types of infections, they are not routes through which TB is typically transmitted. TB does not spread through casual contact or through items like food or surfaces that an infected person may have touched. Thus, understanding the correct transmission route is crucial for effective prevention and control measures against TB.
