World TB Day – 24 March
The theme of this year’s World TB Day is: « Unite to End TB »
World TB Day, falling on March 24th each year, is designed to build public awareness that tuberculosis today remains an epidemic in much of the world, causing the deaths of nearly one-and-a-half million people each year, mostly in developing countries.
It commemorates the day in 1882 when Dr Robert Koch astounded the scientific community by announcing that he had discovered the cause of tuberculosis, the TB bacillus. At the time of Koch’s announcement in Berlin, TB was raging through Europe and the Americas, causing the death of one out of every seven people. Koch’s discovery opened the way towards diagnosing and curing TB.

Background
Tuberculosis, or TB, is an infectious bacterial disease caused by Mycobacterium tuberculosis, which most commonly affects the lungs. It is transmitted from person to person via droplets from the throat and lungs of people with the disease. WHO estimates that the largest number of new TB cases in 2005 occurred in south-east Asia, which accounted for 34 percent of incident cases globally. However, the estimated incidence rate in sub-Saharan Africa is nearly twice that of south-east Asia.
