Complications of Latent tuberculosis: On the average, people infected with M. tuberculosis have a 10 percent chance of developing active TB at some time in their lives. The risk of developing active disease is greatest in the first year after infection, but active disease often does not occur until many years later.¹

TB bacteria become active if the immune system can't stop them from growing. The active bacteria begin to multiply in the body and cause TB disease. Some people develop TB disease soon after becoming infected, before their immune system can fight the TB bacteria. Other people may get sick later, when their immune system becomes weak for some reason.²

Many people who have TB infection never develop TB disease. But some people who have TB infection are more likely to develop TB disease than others. These people are at high risk for TB disease. They include

• people with HIV infection

• people in close contact with a person who has infectious TB

• people who became infected with TB bacteria in the last 2 years

• babies and young children

• people who inject drugs

• people who are sick with other diseases that weaken the immune system

• elderly people
