Tuberculosis Services

Tuberculosis (TB) is a disease caused by the bacterium Mycobacterium tuberculosis being spread from one person to another through the air. It usually affects the lungs, but can also cause infection in other parts of the body. The bacteria enter into the air when a person with TB of the lung or throat coughs, sneezes, laughs or sings. If another person breathes in these bacteria, there is a chance they will become infected with tuberculosis. However, not everyone infected with the bacteria will develop TB disease because their body's natural defenses will protect them. Additional information on tuberculosis is available through the American Lung Association.

Latent TB Infection Vs. TB Disease

TB Infection

The term latent TB infection means that a person has the bacteria in their body, but the germs are being kept inactive by the body. They do not have symptoms of disease and cannot spread the bacteria to others. These people may develop active disease at a later time, if something happens which makes the body less able to protect itself. Medication is often prescribed for these people to prevent them from developing disease.

TB Disease

People with TB disease are sick with bacteria that are active in their body. Most people with active disease have 1 or more of the symptoms of TB. The symptoms could include feeling weak, weight loss, persistent cough, chest pain, loss of appetite, night sweats, and/or coughing up blood. Other symptoms can occur when the disease happens in a part of the body other than the lungs. Someone with TB disease can spread it to others. Medicines which can cure the disease are prescribed for these people.
