Global health leaders have converged in France to pivot the “One Health” philosophy from a theoretical framework into a series of operational mandates. During a milestone summit held on World Health Day, the World Health Organization (WHO) and its international partners unveiled a suite of high-impact initiatives designed to break down the silos between human medicine, veterinary science, and environmental protection.
The shift toward WHO and France shift One Health vision to action with latest high-impact initiatives comes as the international community grapples with the reality that the majority of new infectious threats are not isolated human events, but biological spills from animals. By integrating surveillance across different sectors, the initiative seeks to identify pathogens in wildlife or livestock before they jump to human populations.
The scale of the risk is underscored by the fact that roughly 60% of known infectious diseases in humans originate in animals, with approximately 75% of emerging infectious diseases being zoonotic. The economic and human cost of failing to manage these interfaces was laid bare by the COVID-19 pandemic, which resulted in an estimated 15 million deaths and caused trillions of dollars in global economic losses between 2020 and 2021.
For physicians and public health experts, this approach represents a necessary evolution in pandemic preparedness. It acknowledges that climate change, biodiversity loss, and water contamination are not merely environmental issues, but primary drivers of disease emergence. As Dr. Tedros Adhanom Ghebreyesus, Director-General of WHO, noted during the summit, the health of people, animals, and the environment are “inextricably interwoven,” meaning no single sector can be protected in isolation.
Operationalizing the One Health Framework
To move beyond diplomatic commitments, the WHO and its “Quadripartite” partners—which include the Food and Agriculture Organization (FAO), the United Nations Environment Programme (UNEP), and the World Organisation for Animal Health (WOAH)—have launched four specific pillars of action.
The first is the creation of a Global Network of One Health Institutions. This network is designed to translate high-level global guidance into practical, on-the-ground tools for member states. By leveraging the WHO Academy, the initiative will provide multidisciplinary training to ensure that a veterinarian in one region and a public health officer in another are using the same data and protocols to monitor emerging threats.
The second pillar focuses on the scientific foundation of these efforts. The mandate of the One Health High-Level Expert Panel (OHHLEP) has been extended through 2027, with a subsequent phase planned for 2027–2029. This ensures that the global research agenda remains grounded in evidence rather than political expediency, specifically in the areas of advocacy and the One Health Joint Plan of Action.
Targeting Immediate Threats: Rabies and Avian Influenza
Although much of the summit focused on future pandemics, two immediate health crises were prioritized for urgent intervention. The first is a renewed push to eliminate dog-mediated human rabies deaths by 2030. Rabies continues to be a devastating disease, killing nearly 60,000 people annually, many of whom are children. In partnership with the Institut Pasteur and WOAH, the initiative will leverage rabies elimination as a “proof of concept” for how One Health surveillance can work in endemic countries.
Simultaneously, the partners presented a new Strategic Framework for Collaboration on avian influenza. This framework aims to replace fragmented, country-by-country responses with a unified strategy. The goal is to synchronize surveillance and risk assessment to protect not only human health but also food security and biodiversity, as avian flu can devastate livestock populations and wild bird colonies alike.
| Initiative | Primary Objective | Key Partners |
|---|---|---|
| Global Network of Institutions | Translate guidance into local action | WHO, FAO, UNEP, WOAH |
| OHHLEP Extension | Scientific guidance through 2029 | Quadripartite Partners |
| Rabies Elimination 2030 | Zero dog-mediated human deaths | WHO, WOAH, Institut Pasteur |
| Avian Influenza Framework | Unified surveillance and response | Quadripartite Partners |
A New Era of Global Coordination
The structural reorganization of the Quadripartite collaboration is perhaps the most significant administrative shift. The WHO has assumed the Chairmanship of the partnership, taking on an enhanced leadership role to streamline governance. This move is intended to reduce the bureaucratic friction that often occurs when agricultural, environmental, and health agencies attempt to collaborate during a crisis.
President Emmanuel Macron of France emphasized that this transition is about moving “from ambition to implementation.” By hosting the summit and the subsequent Global Forum of WHO Collaborating Centres, France is positioning itself as a catalyst for the scientific partnerships required to make this vision a reality. The Global Forum, which convened over 800 collaborating centres from more than 80 countries, serves as the engine for data sharing and capacity-building.
This collaborative effort is expected to feed directly into the G7 discussions on preparedness. By aligning the interests of heads of state with the technical expertise of the WHO Collaborating Centres, the goal is to create a sustainable funding model for “preventative health” that looks beyond the hospital walls and into the ecosystems where diseases begin.

The immediate next step for this initiative is the implementation of the new Strategic Framework for avian influenza and the rollout of the Global Network of One Health Institutions. Progress on these fronts will be monitored through the ongoing mandate of the OHHLEP and reported in subsequent WHO global health updates.
