TB is a serious disease that usually attacks the lungs, but can also affect other parts of the body, including the lymph nodes, kidneys, urinary tract, and bones.
Most people who are exposed to TB bacteria do not develop TB disease. Sometimes, your immune system can kill the TB germs, but when this does not happen, the bacteria can remain alive but inactive in your body. This is called latent TB infection (also known as LTBI). If you have latent TB infection, you have no symptoms, are not sick, and present no risk of spreading the bacteria to others.
TB infection can become TB disease (also known as active TB) if your immune system cannot stop the TB bacteria from growing. The risk of developing TB disease is highest in the first two years after being infected. About 10% of infected people will develop TB disease at some point in their lives.
