Tuberculosis (TB)

What is TB?

TB is a disease that mainly affects the lungs, but can be found in any other body organ. It is caused by a germ called Mycobacterium tuberculosis.The germs are present in the sputum coughed up by those that have TB of the lungs. The germs usually destroy the soft tissue of the lungs, and this causes cavities (holes) in the lungs, resulting in difficulty with breathing, and blood can be coughed up. If untreated, TB can cause death.

How to people get TB?

The disease is passed on from person to person. When a person who has TB coughs, sneezes or spits, germs are spread into the air from where they can be breathed in. Fortunately not all those infected contract TB, in most cases the germs are sealed off in the body and they do not multiply. However, if the body's defenses can no longer control the germs, they become active and the person gets TB.

Treatment must be completed

It is a mistake to stop taking medicines when a person feels better. All treatment / medicine must be taken for the full 6 months. If treatment / medicine is missed, the risk of a drug resistant strain of TB is possible. This TB is very difficult to treat and needs more than 18 months of treatment / medicine, with a long stay in hospital. It takes a long time for TB germs to be destroyed. If medicines are stopped too soon and without instructions of the nurse or doctor the disease may start all over again.

TB and HIV Interactions

In people with healthy immune systems, only 10% of those who are infected with TB ever become sick from TB. Over 50% of people who are co-infected with TB and HIV will get sick with TB before they die. HIV increases the risk of developing TB. Not all HIV-positive people have TB. Not all people with TB are HIV-positive. HIV and AIDS is common in socio-economically stressed communities, and these same communities are also vulnerable to TB.
