TB is caused by bacteria known as Hycobacterium Tuberculosis and it usually infects the lungs. Anyone can be infected by breathing in the bacteria, especially if your immune system is compromised. 

TB is spread through the air when a person with untreated TB coughs, sneezes, sings or talks.

TB can be cured, even if you have HIV, by taking treatment as prescribed. 

Signs and symptoms of  TB:

  • Coughing for more than 2 weeks or if HIV positive, coughing for any length of time
  • Loss of appetite or unexplained weight loss
  • Night sweats
  • Fever

If you have any of these symptoms, go to a clinic to be tested for TB

DR-TB can result from:

  • not completing previous TB treatment or
