TB Signs and Symptoms

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
  • Chills
  • Fever
  • Night sweats

Other symptoms depend on the part of the body that is affected.

You should get tested for TB if:

  • You have spent time with a person known or suspected to have TB disease
  • 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
  • You inject illegal drugs

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.
