UCL Health of the Public Symposium 2026 – Transforming Health: From Sickness to Prevention is a major academic and public health event organised by UCL Health of the Public at University College London on 29 April 2026. Held at the Kennedy Lecture Theatre within the Great Ormond Street Institute of Child Health in London, United Kingdom, this one-day symposium brings together researchers, public health leaders, healthcare practitioners and policy makers to explore bold strategies that shift health systems from treating sickness towards prioritising prevention. Reflecting the themes of the NHS 10-Year Plan, sessions will focus on reducing preventable risk factors such as obesity, tobacco use and harmful alcohol consumption while enhancing mental health support and community-based preventive approaches.
