Most people recover from primary TB infection without further evidence of the disease. The infection may stay inactive (dormant) for years. In some people, it becomes active again (reactivates).
TB is caused by the bacterium Mycobacterium tuberculosis (M tuberculosis). TB is contagious. This means the bacteria is easily spread from an infected person to someone else.
