TB usually occurs in the lungs, but it can also occur in other parts of the body, such as the brain, kidneys, or spine.
Symptoms of TB of the lungs include:
- A bad cough that lasts 3 weeks or longer
- Pain in the chest
- Coughing up blood or sputum (phlegm from deep inside the lungs)
General symptoms of active TB include:
- Weakness or fatigue
- Unexplained weight loss
- Loss of appetite
- Night sweats
Other symptoms depend on the part of the body that is affected.
You should get tested for TB if:

- You are HIV positive or have another condition that puts you at high risk for developing TB disease
- You think you might have TB
- You are from a country where TB disease is common (most countries in Latin America and the Caribbean, Africa, Asia, Eastern Europe, and Russia)
- You live in a place where TB disease is more common such as a homeless shelter, migrant farm camp, prison or jail, and some nursing homes

If you think you may have been exposed to a person with TB disease, contact your health care provider or your local TB control office.
