About TB

What is TB?

TB is an infection caused by bacteria  which mainly affects the lungs but can affect other parts of the body. Only TB carried in the lungs is infectious.

If not treated properly, TB can be fatal. An individual might be infected with TB for years but have no symptoms. If the immune system becomes less effective, then the disease can become active.

Poverty & TB

TB is a disease of poverty. 95% of new TB cases and 98% of all TB deaths are in the developing world. More than half of all deaths occur in Asia.

The risk of becoming infected with TB is increased due to malnutrition, overcrowding, poor air circulation, and poor sanitation – all these factors are associated with poverty.
