Tuberculosis (TB) spreads through the air from one person to another.

TB germs spread when a person with infectious TB disease coughs,
speaks, or sings.

  • TB germs usually attack the lungs but can also move to any part of the body.
  • TB germs can live in the body without making you sick.
  • This is called latent TB infection or inactive TB.
  • TB germs can live in your body for years without causing symptoms.
  • Without treatment, inactive TB can develop into active TB disease and make you sick.
  • If you have inactive TB, you can take TB medicine to prevent the
    development of active TB disease even if you do not feel sick.
