Facts about Tuberculosis (TB)

  • An airborne, highly contagious, infectious disease caused by the bacteria Mycobacterium tuberculosis.
  • In Malaysia, 26,168 new TB cases were reported in 2017 (2).

What is latent TB infection (LTBI)?

  • LTBI refers to a person’s exposure to the M. tuberculosis bacterium but they do not show any signs or symptoms of TB disease.
  • It is not contagious, and people can carry it for a very long period until it converts into an active, contagious form of the disease.
  • Treatment of LTBI can prevent conversion into an active form.

Treating LTBI prevents active TB

  • Identification and treatment of LTBI can substantially reduce the risk of development of active disease by as much as 60% (3).
