  • TB is caused by a bacterium named Mycobacterium tuberculosis.
  • The bacteria that cause TB can be spread when an infected person coughs or sneezes.
  • Most people infected with the bacteria that cause tuberculosis do not exhibit symptoms.
  • When symptoms do occur, they usually include a cough which can sometimes beblood-tinged, weight loss, night sweats and fever.
  • Treatment isn’t always necessary for those who do not show symptoms.
  • Patients who are presented with active symptoms will require a long course of treatment involving multiple antibiotics.

  • Latent TB is also called inactive TB or TB infection and it is not contagious.
  • Latent TB can turn into active TB, hence treatment is highly recommended.
Active TB
  • Also known as TB disease, this condition makes you sick and, in most cases, can be contagious.
