World Health Day
On 7 April 2026, the global community marks World Health Day on the theme Together for health. Stand with science.
Science is at the heart of solutions to today’s most pressing health challenges – from preventing zoonotic diseases and improving food safety to safeguarding ecosystems and ensuring sustainable agrifood systems. This year’s campaign highlights how evidence-based action and international cooperation can transform knowledge into real-world impact.
For FAO, World Health Day is an opportunity to spotlight the essential role of science in achieving safe, nutritious food, resilient agrifood systems and healthier lives. FAO works with countries and partners to strengthen scientific capacities, promote innovation and support policies grounded in evidence.
A key focus of the 2026 campaign is the One Health approach, which recognizes the interconnected health of people, animals, plants and ecosystems. Through One Health, FAO collaborates with global partners to address shared threats such as zoonotic diseases, antimicrobial resistance, foodborne illnesses and environmental risks.
