Did you know 1 in 4 people carry Latent Tuberculosis (LTBI) without showing symptoms?
While silent, 5–10% will develop Active TB, which is contagious and potentially deadly if untreated.
Why it matters:
Latent TB has no symptoms and can only be detected by tests like IGRA or TST.
Without detection and treatment, LTBI can progress to active TB, spreading within communities.
IGRA testing is recommended by WHO, CDC, and ECDC for reliable diagnosis of LTBI.
