	'''Latent tuberculosis''' (LTB) refers to a state in which the ''Mycobacterium tuberculosis'' bacteria are present in the body but remain inactive. People with latent TB do not exhibit symptoms and are not contagious. However, they are at risk of developing active tuberculosis if their immune system weakens.

== Latent Tuberculosis: A Silent Threat ==

'''Latent tuberculosis''' (LTB) refers to a state in which the ''Mycobacterium tuberculosis'' bacteria are present in the body but remain inactive. People with latent TB do not exhibit symptoms and are not contagious. However, they are at risk of developing active tuberculosis if their immune system weakens.

While latent tuberculosis poses a silent threat, understanding, early detection, and treatment are essential steps in preventing the progression to active TB and further spread of this age-old disease.
