Not all people with tuberculosis will get sick.
Symptoms of tuberculosis can be similar to other illnesses. The most common symptoms of active tuberculosis disease are:
- a cough lasting 3 weeks or more
- coughing up thick mucus or blood
- night sweats
- loss of appetite
- weight loss
- swollen glands, usually in your neck
- chest pain.
Symptoms that develop later
Coughing up blood is a widely known symptom of pulmonary (lung) tuberculosis. But, if this happens, it will be a long time after you are infected.
Tuberculosis can stay inactive in your body for many years before it develops. This is called latent tuberculosis infection.
Latent tuberculosis infection
Even though you feel well and healthy, your healthcare provider may still advise treatment to make sure you do not develop tuberculosis disease.
