The Union is a scientific, technical and membership organisation. Established in 1920, The Union strives to end suffering due to tuberculosis and lung diseases, old and new, by advancing better prevention and care. We seek to achieve this by the generation, dissemination and implementation of knowledge into policy and practice.​ We aim to ensure that no-one is left behind, people are treated equally and we have a focus on vulnerable and marginalised populations and communities.
