Tuberculosis

What is tuberculosis (TB)?

Tuberculosis (TB) is a bacterial disease that usually attacks the lungs. But it can also attack other parts of the body, including the kidneys, spine, and brain.

Not everyone infected with TB bacteria (germs) becomes sick. So, there are two types of TB conditions:

TB is found in the U.S., but it is more common in certain other countries.

What causes tuberculosis (TB)?

TB is caused by bacteria (germs) called Mycobacterium tuberculosis. The germs spread from person to person through the air. People who have TB disease in their throat or lungs spread the germs in the air when they cough, sneeze, talk, or sing. If you breathe in the air that has the germs, you can get TB. TB is not spread by touching, kissing, or sharing food or dishes.

You're more likely to catch TB from people you live or work with than from people you see for shorter amounts of time.

Who is more likely to get infected with tuberculosis (TB) germs?

Anyone who is near a person with TB disease can get infected with the germs. You are more likely to be near someone with TB disease if you:

Who is more likely to develop TB disease?

Certain people are more likely to get sick with TB disease after they get infected. They include people who:

What are the symptoms of tuberculosis (TB)?

Most people who have TB germs in their bodies don't get sick with TB disease. Instead, they have latent TB infection. With a latent TB infection, you:

If you have TB disease, the TB germs are active, meaning that they are growing (multiplying) inside your body and making you sick. If the TB is growing in your lungs or throat, you can spread the TB germs to other people. You can get sick with TB disease weeks to years after you're infected with TB germs.

With TB disease, your symptoms will depend on where the TB is growing in your body

How is tuberculosis (TB) diagnosed?

Your health care provider or your local health department can test you to find out if you have TB germs in your body. They will give you either a TB skin or blood test.

If your test shows that you have TB germs, you'll need to have other tests to see if the germs are actively growing:

You may need a TB test if you have symptoms of TB disease or if you are at high risk because you are more likely to be near someone with TB disease.

What is the treatment for tuberculosis (TB)?

The treatment for both latent TB infection and TB disease is antibiotics. To make sure you get rid of all the TB germs in your body, it's very important to follow the directions for taking your medicine.

If you don't follow the directions, the TB germs in your body could change and become antibiotic resistant. That means the medicine may stop working and your TB may become hard to cure.

By following medical advice for TB testing and treatment, you can keep yourself healthy and help stop the spread of TB.
