Latent Tuberculosis Infection (LTBI) (or "sleeping TB") arises when an individual is infected with Mycobacterium tuberculosis (TB) but the bacterium is dormant and not transmissible (does not have active disease). Individuals with LTBI are more likely to progress to active TB if they do not receive and adhere to treatment.

For more information, see the section titled 3.2. Identifying Latent Tuberculosis Infection (LTBI) in Manitoba in the Tuberculosis (TB) - Method of Identification concept.
