World Health Day 2026, observed on 7 April, calls on people everywhere to stand with science. Under the theme “Together for science”, this year’s observance launches a year‑long campaign celebrating the power of scientific collaboration to protect the health of people, animals, plants, and the planet. The campaign spotlights both scientific achievements and the multilateral cooperation needed to turn evidence into action – through a strong focus on the One Health approach.
Anchoring the 2026 campaign are two major global moments: the International One Health Summit (7 April), hosted by WHO and the Government of France under the French G7 Presidency, and the inaugural Global Forum of WHO Collaborating Centres (7–9 April), gathering nearly 800 scientific institutions from over 80 countries. Together, these events form the largest scientific network ever convened around a United Nations agency, underscoring how science‑driven partnerships can build a healthier, safer future for all.
The campaign invites people everywhere to participate – by celebrating scientific achievements, engaging with evidence, sharing personal stories of how science improves lives, and joining the global conversation through #TogetherForScience.
Campaign goals
The campaign calls on governments, scientists, health workers, partners, and the public to:
- stand with science by engaging with evidence, facts, and science-based guidance to protect health;
- rebuild trust in science and public health; and
- support science-led solutions for a healthier future.
