Reactivation TB may occur if the individual’s immune system becomes weakened and no longer is able to contain the latent bacteria. The bacteria then become active; they overwhelm the immune process and make the person sick with TB. This also is called TB disease.
When does latent TB become active?
However, latent TB bacteria can ‘wake up’ and become active in the future, making you ill. This can happen many years after you first breathe in TB bacteria. Latent TB bacteria are more likely to wake up if you experience lifestyle stresses or other illnesses that weaken your immune system.
