Tuberculosis (TB)

Community

Tuberculosis (TB) is an infectious disease spread by tiny germs that can float in the air. TB germs can spread when a person with TB coughs, shouts or sneezes. People nearby can breathe TB germs into their lungs.

Tuberculosis (TB)TB Infection and TB Disease are two different things:

Latent Tuberculosis Infection (LTBI or TB infection) means that a person has TB germs in their body but they are dormant (asleep). A person with LTBI cannot spread the TB germ to other people.

Active Tuberculosis (active TB or TB disease) means that the germs are growing in the body and causing damage. TB usually attacks the lungs but can also be in the kidneys, brain or other parts of the body. People with active TB need treatment to prevent it from getting worse or spreading to others.
