The day aims to promote trust in science, encourage the use of evidence-based health decisions, and support science-led solutions for a healthier future.
The day is organised by the WHO and launched a year-long global campaign promoting scientific collaboration for health.
The campaign focuses on the “One Health approach,” which connects the health of humans, animals, plants, and the environment.
Two major events support the campaign: the International One Health Summit (hosted by France under G7 Presidency) and the Global Forum of WHO Collaborating Centres (7–9 April 2026).
The theme for the year 2026 is “Together for health. Stand with science.”
