 Basic TB Facts:

     Tuberculosis, also known as "TB" is caused by the bacterium called Mycobacterium Tuberculosis.  The bacteria usually attack the lungs, but TB bacteria can attack any part of the body such as the kidney, spine, and brain.  TB disease can be fatal if not treated properly.

How TB is Spread:

     TB is spread through the air from one person to another.  The TB bacteria are put into the air when a person with active TB disease of the lungs or throat coughs, sneezes, speaks, or sings.  People nearby may breathe in these bacteria and become infected.

Latent TB Infection and TB Disease:

     Not everyone infected with TB bacteria becomes sick.  As a result, two TB-related conditions exist.  Latent TB infection and active TB disease.

Latent TB Infection:

     In most people who breathe in TB bacteria and become infected, the body is able to fight the bacteria to stop them from growing.  This is called latent TB infection or LTBI.  People with latent TB infection do not feel sick and do not have any symptoms.  The only sign of TB infection is a positive reaction to the tuberculin skin test.  People with latent TB infection are not infectious and cannot spread TB bacteria to others.  However, if TB bacteria become active in the body and multiply, the person will get sick with TB disease.

TB Disease:

     When TB bacteria are active (multiplying in your body), this is called TB disease.  People with TB disease may spread the bacteria to people they spend time with every day.  Many who have latent TB infection never develop TB disease.  For persons whose immune systems are weak, especially those with HIV infection, the risk of developing the TB disease is much higher than for persons with normal immune systems.
