When we talk of public health anywhere in the world, whether it is disease elimination, targets, surveillance and related efforts, the first reference point is often the World Health Organization. It is difficult to imagine a world without a central body coordinating efforts to prevent and eliminate diseases. Yet it has only been active since 1948. In that relatively short span, the world has seen significant scientific and medical progress, from vaccine development to large-scale disease control efforts such as the near-elimination of Polio.

However, in recent years, that centrality has come under closer scrutiny. As global alignment on health priorities weakens, the question is no longer what this institution does, but how much the world is still willing to act together in addressing shared health challenges.

For much of its history, this global health institution operated with broad agreement across countries, even amid periodic criticism and differing approaches. That shared understanding, however, has come under strain, reflecting deeper geopolitical shifts and competing national priorities. Moments such as the United States’ decision to withdraw from the organisation in early 2026, citing concerns over its handling of the COVID-19 pandemic, have highlighted how cooperation in health is shaped as much by political considerations as by scientific evidence and technical expertise.

Public health today is as much about trust as it is about treatment.

For India, the relevance of this global health institution is both immediate and far-reaching. As one of the world’s largest and most complex health systems, India has been central to many international health priorities, from disease control to strengthening primary healthcare and expanding access. Its success in eliminating Polio remains a defining public health achievement, demonstrating what sustained political commitment, administrative coordination and community mobilisation can deliver. Yet persistent challenges, from non-communicable diseases to uneven access to care across regions, continue to highlight the unfinished agenda of health for all. As India expands its health infrastructure, digital systems and service delivery models, its engagement with global frameworks will shape how these commitments are applied within national systems.

Beyond specific diseases, the real test now lies in systems and trust. The organisation was built on the assumption that countries would act collectively in the face of shared risks, an assumption that is increasingly under strain. Actual global coordination, in practice, has often been uneven and slow. Marked on 7th April, the founding day of the World Health Organization , World Health Day serves as a reminder of its enduring relevance. This year’s World Health Day theme, “Together for health. Stand with science.”, reinforces the continued importance of evidence-based action, collective responsibility and sustained cooperation across borders. For India, this is not abstract. Strengthening primary healthcare, investing in prevention and building resilient systems will determine whether global commitments result in real improvements in access, affordability and quality of care.

In a world increasingly marked by conflict and division, health is often one of the first casualties where systems weaken, access breaks down and the most vulnerable are pushed further to the margins. The idea of cooperation in health, therefore, is not just about managing diseases, but also about preserving a shared commitment to human well-being in times of uncertainty and instability. In that sense, the pursuit of health is inseparable from the pursuit of stability and peace. In the lead-up to 7th April, World Health Day, the question is not whether the World Health Organization is perfect, but whether the world can afford a future without effective international cooperation in health. In that sense, it is less of a solution and more of a test, of whether nations are still willing to act together when it matters most.
