  • Sweating especially at night
  • Tiredness or fatigue

Common causes

What's common causes of tuberculosis?

A person needs to inhale only a few germs to become infected with a bacteria called mycobacterium that spread from person to person through microscopic droplets released into the air. This can happen when someone with the untreated, active form of tuberculosis coughs, speaks, sneezes, spits, laughs or sings.

Departments & Emergency

If an individual has sign or symptoms it is recommended to see:

  • Emergency Room
  • General Practitioner
  • Internal Medicine Specialist
  • Pulmonary Medicine Specialist
  • Allergy and Immunology Specialist


It can be diagnosed by: 

  • Medical History
  • Physical Examination
  • Skin Test
  • Sputum Tests
  • Blood Tests
  • Imaging Tests


  • Medical help such as antibiotics.
  • Be caution when touching someone who has TB.
  • Attention to hygiene such as hand washing


How is tuberculosis spread?

It is spread through the air from one person to another.

Can you get tuberculosis again?

Even if it has been treated successfully, people that have beat tuberculosis, can get tuberculosis infection again.

Am I protected from TB if I have been vaccinated with BCG?

BCG vaccine protects against the severe, life-threatening forms of extra-pulmonary TB such as TB meningitis and miliary TB in childhood. However, it is unreliable protection against pulmonary TB, the main form of tuberculosis.

Once a person completes treatment for TB disease and is cured, can he/she get TB again?

This is unlikely but can, rarely, occur. If the patient has taken the medicine in the right way for as long as the doctor advises, the chances of getting TB again are low.
