World Health Day 2026

On World Health Day 2026, WHO unites and mobilizes the world under the theme “Together for health. Stand with science” celebrating the power of scientific collaboration to protect the health of people, animals, plants, and the planet. The year‑long campaign spotlights both scientific achievements and the multilateral cooperation needed to turn evidence into action.

We call on governments, scientists, health workers, partners, and the public to stand with science to protect lives, rebuild trust, and secure a healthier future.
 

 

Call to action: stand with science

Choose evidence. Trust facts. Support science-led health, for people, animals, and the planet.
 

Ask. Share. Stand with science.

  • Ask a health question that matters to you.
  • Share how science helps solve it.
  • Join the global conversation with #StandWithScience and #WorldHealthDay.


Commit to science-based policy and One Health action

Governments and institutions are called to strengthen investment in science, support WHO’s normative role, and embed evidence in health, climate, food, and environmental decision-making.


Activate. Explain. Lead.

Collaborating Centres and the scientific community are mobilized to make science accessible and understandable, share clear explanations of evidence, engage with the public, and serve as visible, trusted voices championing facts and science-based solutions.


Be ambassadors of science

Show patients and communities how science guides care, and why evidence saves lives.


 

Key events

Anchoring the 2026 campaign are two major global moments: the international One Health Summit (5–7 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 scientific institutions from over 80 countries.

Together, these events form the largest scientific network ever convened around a United Nations agency, underscoring how scienced driven partnerships can build a healthier, safer future for all.
 

 


Science serves everyone, everywhere

WHO and its partners work around the clock to generate scientific knowledge on key health priorities, sharing evidence and strengthening countries’ research capacities and systems for more equitable access to health care.
 

Science powers health

The future will be shaped based on how we develop and practice science-led approaches for the health of all – not only humans, but also animals, plants, ecosystems and the entire planet – through the One Health approach.
 


Stand with science

Progress in public health is built on global solidarity and collaboration. WHO’s ability to connect science with real-life practice in communities and countries around the world is powered through its network of 800 collaborating centres.
