Q:
What is tuberculosis and what causes it?

A:
Definition

Tuberculosis (TB) is a potentially serious infectious disease that mainly affects your lungs. It is contagious because the bacteria that cause tuberculosis are spread from one person to another through tiny droplets released into the air via coughs and sneezes.

Causes

Tuberculosis is caused by bacteria that spread from person to person through microscopic droplets released into the air. If a person with tuberculosis is untreated, active form of tuberculosis coughs, speaks, sneezes, spits, laughs or sings.

It’s actually much more likely to get tuberculosis from someone you live with or work with than from a stranger. Most people with active TB who’ve had appropriate drug treatment for at least two weeks are no longer contagious.
