Science at the Heart of Global Health
Every year on April 7, the World Health Organization (WHO) marks World Health Day. Established in 1950, this day highlights the remarkable progress made in public health since the WHO was founded in 1948, while also reminding us of the challenges that remain.
Over the decades, scientific advances, prevention policies, and international cooperation have significantly improved people’s quality of life. Today, this day continues to encourage collective action to “protect the health of people and the planet” and to promote societies centered on well-being.
A Unifying Theme for 2026
For the 2026 edition, the WHO is launching the campaign “Let’s Unite for Health. Let’s Support Science.” This theme underscores the essential role of scientific research and international collaboration in turning knowledge into concrete action. It aligns with the “One Health” approach, which recognizes the close connections between human, animal, and environmental health.
Global-Scale Events
Two major events mark this campaign:
• The international “One Health” Summit on April 7, organized by the WHO and the Government of France
• The first Global Forum of WHO Collaborating Centres, from April 7 to 9, bringing together nearly 800 scientific institutions from more than 80 countries
These gatherings highlight the importance of scientific partnerships in building a healthier and safer future worldwide.
An Invitation to Take Part
The WHO invites the public to join this global movement by:
• highlighting scientific achievements
• relying on trusted data
• sharing concrete experiences
• joining the online conversation using the hashtag #StandWithScience
The campaign’s objectives are clear: to strengthen trust in science, promote evidence-based decision-making, and encourage sustainable solutions for everyone’s health.
An Ongoing Commitment
World Health Day is part of the WHO’s major international campaigns, alongside initiatives such as World No Tobacco Day, World Immunization Week, and World AIDS Day.
These are all opportunities to remind us that health is a shared responsibility and a collective commitment to the future.
