Tuberculosis

What is Tuberculosis?

Tuberculosis, also known as TB, is a disease caused by bacteria spread through the air from one person to another. Commonly, it attacks the lungs, but also other parts of the body. It is estimated that one third of the world's population is infected with TB, but it can lay latent, meaning not everyone develops the active disease. Persons with latent TB do not spread the disease unless it is active in the body. Of all TB cases in the world, 85 percent occur in 22 countries. Of these 22 countries, 9 are in sub-Saharan Africa and over 1.5 million cases of TB occur in Africa each year. In Africa TB/HIV co-infection is one of the main causes of morbidity and mortality in Africa. A 3-5 drug regimen using Directly Observerd Therapy – Short course (DOTS) over a 6-8 month period is the standard of treatment for TB. Treatment failures result in drug resistance including multi-drug resistence.
