What Is Tuberculosis?
2. Causes
Tuberculosis (TB) is caused by a bacterium that is known as Mycobacterium tuberculosis. It is spread when an infected person coughs, sneezes, or exhales, releasing infected droplets into the air. Other people in the vicinity may then inhale these droplets, potentially resulting in an infection.
It is not easy for somebody to catch tuberculosis, and it is unlikely that you will catch it from a stranger in public. Instead, you are a lot more likely to catch it from somebody that you spend a lot of time with. What’s more is that a person infected with tuberculosis is not always contagious.
