“A person with active TB will have symptoms. A person with latent, or inactive, TB will have no symptoms.

You may still have a TB infection, but the bacteria in your body is not yet causing harm. You may experience other symptoms related to the function of a specific organ or system that is affected. Coughing up blood or mucus (sputum) is a sign of in TB of the lungs. Bone pain may mean that the bacteria have invaded your bones.

These symptoms can also occur with other diseases, so it is important to see a healthcare provider and to let them find out if you have TB. If you think you have been exposed to TB, get a TB test.”
