“Together for health” is this year’s theme. “Stand with science” has a weight that wasn’t quite necessary for earlier themes. With this campaign, the WHO is not only commemorating scientific advancements. It’s protecting it. The call to stand with science is less a celebration than a counteroffensive in a world where false information spreads more quickly than peer-reviewed research can respond, where anti-vaccine sentiment contributed to avoidable deaths during the COVID-19 pandemic, and where a nation like Pakistan is still one of only two places on earth still dealing with endemic polio. It’s not a subtle observation. It’s the current state of affairs.

This year’s campaign’s anchor events are truly important. Under its G7 presidency, France hosted the International One Health Summit, which united experts in the fields of health, animals, and the environment around the idea that human health is inextricably linked to the health of ecosystems and animal populations. Alongside it, almost 800 scientific institutions from over 80 countries came together for the first Global Forum of WHO Collaborating Centers, creating what WHO calls the largest scientific network ever gathered around a UN agency. Watching researchers from five continents’ worth of institutions compare notes on zoonotic diseases and antimicrobial resistance while standing in the corridors of a summit that size is the kind of moment that makes the theme feel less like a catchphrase and more like something that is actually being built.

Because so many of the health emergencies of the last 20 years—including SARS, H1N1, COVID-19, and a number of others that are still being closely monitored—began at the border between human and animal populations, the One Health framework is important. Without institutional momentum, it is extremely difficult to maintain the kind of cross-disciplinary, cross-border collaboration needed to address that boundary. Part of the goal of the 2026 campaign is to create that momentum while political will is still present, before governments feel comfortable pulling back from multilateral health commitments due to COVID-19.

Observing the social media reaction to this year’s World Health Day gives the impression that it was received differently than previous themed days. Pakistan’s Prime Minister Shehbaz Sharif urged the expansion of digital health and evidence-based health policy. Narendra Modi of India wrote on social media about bolstering healthcare systems. The Maldives explained how their national health strategy directly incorporates scientific knowledge. At a time when doing so isn’t widely accepted, these government officials are openly supporting science. Another, more crucial question is whether the speeches result in budgetary allocations. However, the alignment of rhetoric is important.

Access is the more difficult topic of discussion, which tends to soften on days like these. Less than 1% of Pakistan’s GDP is allocated to healthcare. Its neighbor, Bangladesh, spends more than twice that amount. About half of Pakistanis do not have access to basic primary healthcare. Adolescent diabetes is on the rise at rates that should be concerning but are instead dismissed as a side issue. Approximately 19 million people in Pakistan suffer from undiagnosed hypertension. Campaigns to raise awareness do not alone improve these statistics. They call for consistent public funding at a level that the majority of developing-nation governments have not yet committed to.

The tension at the core of the idea of World Health Day is difficult to ignore. It calls for equal collaboration between some of the world’s most cutting-edge scientific institutions and some of the world’s most underfunded health systems. In theory, everyone has access to the knowledge. The distribution of funding, infrastructure, skilled workers, and supply chains is highly unequal. When diagnosing the interdependence of environmental, animal, and human health, the WHO’s One Health approach is accurate. Every year on April 7, the question of whether the political and economic systems required to address that diagnosis can be constructed in time is raised, but it is never fully resolved.

The best thing World Health Day does is generate a moment of public awareness that might not otherwise occur. Health as a systemic, policy-driven concern often gets lost in the din of every other news cycle, such as election cycles, market volatility, and geopolitical crises. At the very least, there is one day a year when 800 scientific institutions publish at the same time, government officials post messages, and researchers in Tasmania and Tanzania are ostensibly working toward the same goal. It is insufficient. Stand with science is the theme’s advice, and it’s a good one. Since the floor hasn’t been constructed yet, the more difficult question is who gets to stand and who is still seated.
