About Tuberculosis
Tuberculosis, commonly known as TB, is a bacterial infection spread through the air from a person who has active tuberculosis to those who are in close contact. 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 death of tissue in the organs they infect. Active TB disease can be fatal if left untreated.
There are two types of Tuberculosis (TB): Active TB disease and Latent TB infection (LTBI).
How is TB Diagnosed?
TB disease can be diagnosed by medical history, TB Skin Test (TST), Sputum Test, and Chest X-ray.
How is TB Spread?
- TB is spread through the air when a person with Active TB of the lungs coughs the TB germs into the air.
- If you are in the same room, house, workplace or school as the person who is coughing the TB germ into the air, you can become infected.
- When you breathe in the TB germ your body might “lock it up” and it does not make you feel unwell. This is called Latent TB Infection or LTBI.
- If a person’s immune system is not strong the TB germ can wake up and start multiplying.
- HIV, Diabetes and Cancer are some of the health problems that make a person’s immune system weak.
- When you start to develop symptoms of Active TB and start to cough you can now pass on the TB germ to others.
- Active TB can be life threatening if left untreated and can result in death.
TB Prevention, What can we do?
