Latent Tuberculosis Infection (LTBI)

A condition where Mycobacterium tuberculosis is present in the body, but the person does not have tuberculosis (TB). Because the bacteria are inactive, the person does not feel sick and does not have any symptoms of TB. A person with latent TB infection cannot spread TB to others. Without treatment, latent TB infection can advance to TB disease, especially in people with weakened immune systems.
