The WHO launched a year-long campaign, 'Together for health. Stand with science,' to highlight science and collaboration as crucial for global health, marking World Health Day 2026.
Despite significant health improvements like reduced maternal and child mortality due to scientific advancements, new threats from climate change and geopolitical tensions demand continued vigilance and adaptation.
The WHO is organizing a One Health Summit and a Global Forum to foster coordinated action among leaders and scientists, emphasizing that evidence-based decision-making remains paramount for future health challenges.

The World Health Organization (WHO) has launched a year-long public health campaign, “Together for health. Stand with science,” to mark World Health Day 2026. The initiative is framed around the idea that scientific advances and international cooperation remain central to improving health outcomes and managing shared risks across borders.
WHO pointed to major gains it says have been achieved in recent decades, including a 40% reduction in maternal mortality since 2000 and more than 50% fewer deaths among children under five. The organization attributed these improvements to progress in technology and scientific knowledge, alongside cooperation that spans sectors and institutions.
WHO presented these results as evidence that sustained investment in research and coordinated implementation can translate into measurable public health benefits.
At the same time, WHO said the global health landscape is facing new and evolving pressures. It cited climate change, environmental degradation, geopolitical tensions, and demographic shifts as drivers that can intensify existing diseases, stretch health systems, and raise the risk of new epidemics. WHO described these forces as compounding challenges that require countries and partners to work together rather than respond in isolation.
As part of the campaign, WHO is convening a One Health Summit in Lyon, France, and a Global Forum for its Collaborating Centres network. WHO said the meetings are intended to strengthen coordinated action among heads of state, scientists, and community leaders. The organization also said the gatherings are designed to support research and policy development, aligning scientific work with practical decision-making.
WHO emphasized that scientific inquiry should remain the basis for health decisions at every level. It said this includes producing evidence and turning it into action across a wide range of priorities, from infectious diseases to mental health. The campaign’s message, as described by WHO, is that progress depends not only on generating knowledge but also on translating it into policies and services that can be applied consistently.
What remains uncertain, based on WHO’s description, is how quickly coordinated commitments can be converted into durable capacity in health systems facing multiple pressures at once. WHO’s campaign positions science and collaboration as the organizing principles for addressing both long-standing burdens and emerging threats, while using World Health Day 2026 as a focal point for sustained engagement over the year.
