Established in 1920, The Union is the pathfinder of the lung health community.

The Union strives to end suffering due to TB and lung diseases 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.

This annual report provide a summary of The Union’s activities during 2025.
