Frequently Asked Questions

What is TB?

Tuberculosis (TB) is a disease caused by bacteria 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.  Not everyone infected with TB bacteria becomes sick.  As a result, two TB related conditions exist:  latent TB infection and TB disease.  If not treated properly, TB disease can be fatal

How is TB spread?

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

TB is NOT spread by

  • Shaking someone’s hand
  • Sharing food or drink
  • Touching bed linens or toilet seats
  • Sharing toothbrushes
  • Kissing

When a person breathes in TB bacteria, the bacteria can settle in the lungs and begin to grow. From there, they can move through the blood to other parts of the body, such as the kidney, spine, and brain.

TB disease in the lungs or throat can be infectious. This means that the bacteria can be spread to other people. TB in other parts of the body, such as the kidney or spine, is usually not infectious.

People with TB disease are most likely to spread it to people they spend time with every day. This includes family members, friends, and coworkers or schoolmates.

What is Latent TB Infection and TB Disease?

Latent TB Infection

TB bacteria can live in the body without making you sick.  This is called latent TB infection.  Most people who breath in TB bacteria and become infected, the body is able to fight the bacteria and stop them from growing.  People with latent TB infection:

  • Have no symptoms
  • Don’t feel sick
  • Can’t spread TB to others
  • May have a positive TB skin test or positive TB blood test
  • May develop TB if they do not receive treatment for latent TB infection

Many people who have latent TB infection never develop TB disease.  On these people, TB bacteria remain inactive for a lifetime without causing disease.  But in other people, especially people with a weak immune system, the bacteria become active, and cause TB disease.

TB Disease

TB bacteria become active if the immune system can’t stop them from growing.  When TB bacteria are active (multiplying in your body), this is called TB disease.  People with TB disease are sick.  They are able to spread the bacteria to people they spend time with every day.

Many people who have latent TB infection never develop TB disease.  Some people develop TB disease soon after becoming infected (within weeks) before their immune system can fight the TB bacteria.  Other people may get sick years later when their immune system becomes weak for another reason. 

For those whose immune systems are weak, especially those with HIV infection, the risk of developing TB disease is much higher than for people with normal immune systems.
