The mission of the International Union Against Tuberculosis and Lung Disease (The Union) is to bring innovation, expertise, solutions and support to address health challenges in low- and middle-income populations. With nearly 10,000 members and subscribers from 145 countries, The Union has its headquarters in Paris and regional and country offices serving the Africa, Asia Pacific, Europe, Latin America, Middle East, North America and South-East Asia regions. Its scientific departments focus on tuberculosis, HIV, lung health and non-communication diseases, tobacco control and research. The Union is most widely known for the research that led to the global strategy for treating and controlling tuberculosis. Adopted by the World Health Organization in 1993, The Union model is part of the internationally recommended Stop TB Strategy that has been used to treat 32 million people in 202 countries. Drawing on this first success in addressing TB from medical, political, social and organisational perspectives, The Union has since developed programmes addressing TB-HIV, asthma, pneumonia in children under five years of age, and tobacco control. The emphasis is on providing health solutions for the poor.
