1 Tuberculosis – The facts! TB is curable but kills 5000 people every day or 2 million per year. TB is curable but kills 5000 people every day or 2 million per year. 2 billion people (1/3 of worlds population) are infected with the microbes that cause TB 2 billion people (1/3 of worlds population) are infected with the microbes that cause TB 1 in 10 people infected with TB microbes will become sick with active TB in their lifetime 1 in 10 people infected with TB microbes will become sick with active TB in their lifetime TB is contagious & spreads through the air: if not treated each person with active TB infects 10-15 people every year (approx) TB is contagious & spreads through the air: if not treated each person with active TB infects 10-15 people every year (approx) Almost 9 million new cases occurred in 2004 Almost 9 million new cases occurred in 2004

2 What is TB? Tuberculosis is an infectious disease caused by bacteria (mycobacterium tuberculosis) Tuberculosis is an infectious disease caused by bacteria (mycobacterium tuberculosis) The TB bacteria usually attack the lungs but it can also attack the kidneys, spine & brain.

6 Why the global increase of TB? Population growth Population growth Urbanisation Urbanisation Increasing poverty Increasing poverty Rates of HIV infection – this weakens the immune system. If HIV + 100x more likely to develop TB. Rates of HIV infection – this weakens the immune system. If HIV + 100x more likely to develop TB. Drug resistant TB (costs for LEDCs?) Drug resistant TB (costs for LEDCs?) Young adults & women aged 15-44, most at risk Young adults & women aged 15-44, most at risk Poorly managed TB programmes – especially in LEDCs (Africa & SE Asia) Poorly managed TB programmes – especially in LEDCs (Africa & SE Asia)
