WHA/A.2/Res.35
This authority record treats the observance as a fixed annual date. The same month and day can be reused unless a stronger source changes the rule. Public-holiday or government status is never inferred from the observance name alone.
Overview
World Health Day is the World Health Organization’s annual global health observance on 7 April. Each year WHO uses the day to draw attention to a health topic of international concern.
The date also marks the anniversary of the WHO Constitution coming into force in 1948. The observance therefore combines WHO’s institutional anniversary with changing public-health campaigns.
Why it matters
World Health Day creates a shared moment for public-health communication, but its value depends on accuracy. Health campaigns should distinguish population-level information from individualized diagnosis or treatment.
The WHO Constitution places health in a rights-based and international-cooperation framework, making the day relevant to access, prevention, health systems, equity and evidence—not only to personal lifestyle choices.
History
The WHO Constitution came into force on 7 April 1948. WHO identifies that date as the anniversary of its founding.
The First World Health Assembly called for a World Health Day in 1948, and the observance has been celebrated annually on 7 April since 1950 with changing themes focused on priority health issues.

Ways to observe
Use WHO or a competent national health authority to explain the year’s public-health focus and link readers to authoritative resources.
Review whether a school, workplace or community knows where to find credible local health services and emergency information.
Host an evidence-based health education session with a qualified professional and a clearly defined scope.
Examine a public-health issue through prevention, access, equity and systems—not only individual behavior.
Check health claims, statistics and service links immediately before publication because health information can change.
