What is Tuberculosis (TB)?

Tuberculosis is a disease caused by the bacteria mycobacterium tuberculosis that usually affects the lungs but can infect any location in the body. There are two main types of tuberculosis: active and latent. The active form of the disease is highly contagious and is a serious form of TB. Latent TB is a form of the disease in which a healthy person is exposed to TB and the immune system blocks the bacteria from making that particular person sick, they are not contagious and do not have any symptoms, although they may become ill with the active form of TB in the future if not treated.
