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.

A message from WHO Representative to Nepal, a.i.

Call to action: stand with science

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

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

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.

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.

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