It’s important to know that some people may have no symptoms or only mild ones. They may therefore spread bacteria without knowing they have TB.

Tuberculosis symptoms may include the following:

  • A cough that starts out dry but later produces blood or sputum (thick liquid from deep inside the lungs)
  • -Coughing for longer than a month
  • Chest pain
  • Breathing difficulty e.g. shortness of breath
  • Weakness or fatigue
  • Loss of weight and appetite
  • Chills and fevers (the fever may be low and may be intermittent)
  • Joint pain
  • Wheezing
  • Rales (additional sounds made to those of normal breathing)
  • Excessive sweating, including sweating at night
  • Hearing loss
  • Diarrhoea
  • A persistent lump or lesion
  • Clubbing of fingers or toes – the nails become swollen and feel slightly "pulpy".
