World TB day commemorates the date in 1882 when Dr Robert Koch announced 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.
The theme of World TB day 2016 is 'Unite to end TB', a theme selected against the backdrop of the 2030 Sustainable Development Agenda by the United Nations General Assembly.
Ending TB by 2030 is a target of the Sustainable Development Agenda and the goal of the WHO End TB Strategy.
According to the World Health Organisation (WHO), there are about nine million new cases of TB globally each year, of which approximately 1.5 million people die from the disease.
