Tuberculosis, commonly known as TB, is an airborne bacterial infection caused by Mycobacterium and can spread through the lymph nodes and bloodstream to any organ in your body. It is most often found in the lungs. Most people who are exposed to TB never develop symptoms because the bacteria can live in an inactive form in the body. But if the immune system weakens, such as in people with HIV or elderly adults, TB bacteria can become active. In their active state, TB bacteria cause the death of tissue in the organs they infect. Active TB disease can be fatal if left untreated. The good thing is, Tuberculosis is curable and preventable
TB is spread from person to person through the air. When people with lung TB cough, sneeze, or spit, they propel the TB germs into the air. A person needs to inhale only a few of these germs to become infected. About one-third of the world’s population has latent TB, which means people have been infected by TB bacteria but are not (yet) ill with the disease and cannot transmit the disease.
By the end of this module, a nurse assistant will be able to:
1. Identify a basic definition of tuberculosis.
2. Identify the way tuberculosis is spread.
3. Identify the organ that is most commonly affected by tuberculosis.
4. Identify precautions that must be used when caring for a patient with tuberculosis.
