Tuberculosis Control Program Tuberculosis (TB) is a disease caused by a bacteria called Mycobacterium tuberculosis. The bacteria are spread through the air when a person with pulmonary (lung) TB disease coughs, sneezes, talks, or sings. When this occurs, a person nearby may breathe in the bacteria and become infected with TB. 

Untreated TB infection can progress to active TB disease.
TB disease is serious and can be fatal if not treated properly.

TB disease is preventable and curable with medication.

General Information

What is tuberculosis (TB)?

TB is a treatable bacterial disease that is spread from person to person through the air. TB usually affects the lungs, but can affect other parts of the body as well, including the brain, kidneys or spine. TB germs are put into the air when a person with TB disease of the lungs coughs, sneezes, talks or sings. 

What are the symptoms of TB?

Pulmonary (lung) TB:

  • Cough
  • Chest Pain
  • Coughing up blood (Hemoptysis)

General TB disease:

  • Feeling sick or weak
  • Weight loss
  • Fever
  • Chills
  • Night Sweats

    How can you tell if someone has TB?

    The tuberculin skin test (TST) is used to find out whether or not a person is infected with TB germs. For the test, a small amount of tuberculin solution is injected under the skin on the forearm. Two or three days later, a health care worker checks for a reaction on the arm. If it is positive, other tests such as a chest x-ray, will be done to see if the person has TB infection or TB disease.


    What is the difference between TB infection and TB disease?

    TB can take two forms: TB infection and active TB disease.

    Persons with TB Infection

    Persons with Active TB Disease

    • Experiencing no symptoms and does not feel sick
    • Cannot spread TB to others because the bacteria are not active
    • Usually have a positive TST and a normal chest x-ray
    • Can be prescribed medicine to prevent them from developing an active TB disease
    •  May have symptoms that include: prolonged coughing, chills/fever, unexplained weight loss, chest pain, weakness, night sweats
    • May spread TB to others
    • Often have an abnormal chest x-ray

    What does it mean to have a “positive” skin test?

    A positive reaction to the TST does not necessarily mean that a person has active TB disease. A positive TST only shows that the TB germ has infected the person’s body. Everyone with a positive TST should have an x-ray to confirm if there is TB infection or active TB disease. Only about 10% of people infected with TB will go on to develop active TB disease over the course of their lifetime.
