One Health Collaboration: 5 Proven Steps to Global Health

Explore Dr. Zhou Xiao-Nong's proven strategies for One Health collaboration to tackle global health challenges effectively.

One Health collaboration is crucial in today's world where scientific expertise faces unprecedented scrutiny. Visionary leaders like Dr. Xiao-Nong Zhou, Chief Scientist for Parasitic Disease Control at the Chinese Center for Disease Control and Prevention, are pivotal in advocating for collaborative public health approaches. With over 40 years of experience, Dr. Zhou exemplifies how One Health strategies can address humanity's most pressing health challenges by connecting human, animal, and environmental health.

Understanding One Health

One Health collaboration is an integrated approach that acknowledges the fundamental truth: human health cannot be separated from the health of animals and the environment. This concept has gained urgency as zoonotic diseases—those that jump from animals to humans—continue to emerge as major public health threats. Approximately 75% of emerging infectious diseases a

re zoonotic in origin, making the interconnected nature of health systems impossible to ignore.

The One Health framework addresses multiple global challenges simultaneously:

Antimicrobial Resistance: Cannot be controlled without understanding how antibiotics are used in both human medicine and animal agriculture.
Food Security: Depends on healthy ecosystems and disease-free livestock populations.
Climate Change: Impacts human health directly through heat stress and disease vectors, while affecting animal populations and environmental conditions.
Emerging Infectious Diseases: Require surveillance and response systems that span human, animal, and environmental health sectors.

Dr. Zhou's approach to One Health goes beyond theoretical understanding. He emphasizes that "it is important to promote the eradication programme globally by using the One Health approach... involving multi-department cooperation, international action, governance for zoonotic risks, and multi-disciplinary efforts."

Dr. Zhou's Leadership and Accomplishments

Dr. Xiao-Nong Zhou's career spans more than four decades of dedicated work in tropical disease control and parasitic disease management. His positions reflect the trust and respect he has earned within the global health community. As Chief Scientist at the Chinese Center for Disease Control and Prevention, he oversees critical research and implementation efforts. His role as Director of the WHO Collaborating Centre for Tropical Diseases in Shanghai positions him as a key advisor to the World Health Organization on some of the world's most challenging diseases.

China's Historic Malaria Elimination

One of Dr. Zhou's most significant achievements is his instrumental role in China's malaria elimination. On June 30, 2021, the World Health Organization officially certified China as malaria-free, marking the end of a 70-year struggle against the disease. [Source: OAE Publishing Interview] This historic milestone was not achieved through chance or luck—it resulted from sustained, systematic efforts grounded in One Health principles.

Dr. Zhou's work on spatial epidemiology for parasitic diseases and the development of sophisticated surveillance systems provided the scientific foundation for this achievement. The surveillance-response systems he helped develop enabled rapid detection and response to cases, preventing transmission chains from establishing themselves. This success demonstrates that One Health approaches are not theoretical exercises—they produce measurable, life-saving results.

Advancing Global Health Knowledge

Beyond malaria elimination, Dr. Zhou has contributed significantly to global health infrastructure and knowledge dissemination. He founded and serves as Editor-in-Chief of "Infectious Diseases of Poverty" and "Science in One Health," journals that have become essential platforms for publishing research on integrated health approaches. His involvement in WHO expert committees on neglected tropical diseases ensures that his expertise directly influences global health policy and implementation strategies.

The Global One Health Index (GOHI) represents another major contribution. Dr. Zhou's team developed this framework to assess One Health performance across countries and territories. A pilot analysis covering more than 200 countries and territories demonstrated the feasibility of using GOHI to evaluate how well nations are implementing integrated health approaches.

The WFPHA One Health Working Group and Global Advocacy

As Co-Chair of the World Federation of Public Health Associations One Health Working Group, Dr. Zhou leads efforts to advance One Health collaboration on a global scale. The Working Group operates with three primary objectives that reflect a comprehensive strategy for systemic change.

Three Core Objectives

According to Dr. Zhou, "The One Health Working Group has three primary objectives: promote global cooperation to establish One Health platforms, enhance dissemination to influence policy and practice, and improve knowledge and capacity building globally." [Source: WFPHA Interview]

These objectives work together to create systemic change:

Establish One Health Platforms: Creating the institutional structures and networks necessary for different sectors—human health, animal health, environmental management, and others—to work together effectively. Without these platforms, even well-intentioned professionals lack the mechanisms to coordinate their efforts.
Enhance Dissemination and Policy Influence: Translating research findings and best practices into actionable guidance that policymakers and practitioners can implement. The gap between scientific knowledge and policy implementation remains one of the greatest challenges in public health, and Dr. Zhou's work directly addresses this problem.
Improve Knowledge and Capacity Building: Recognizing that One Health approaches require new skills, training, and institutional capabilities. Countries and regions with limited resources need support to develop the expertise necessary to implement integrated health strategies.

Alignment with Public Health Mission

The importance of One Health becomes even clearer when examined through the lens of public health's fundamental mission. Dr. Zhou notes that "The Federation's mission is to protect people and the planet by preventing diseases and promoting health, well-being, and peace. This aligns directly with the One Health concept." [Source: WFPHA Interview] When the fundamental mission of organizations dedicated to public health naturally leads to One Health approaches, it suggests that these integrated strategies represent the future of effective health protection.

Why Champions Matter in an Era of Scientific Skepticism

The importance of leaders like Dr. Zhou cannot be overstated in the current global context. Scientific and medical expertise faces increasing pushback from various quarters. Misinformation spreads rapidly, vaccine hesitancy persists, and evidence-based medicine sometimes takes a backseat to ideology or commercial interests. In this environment, respected voices advocating for rigorous science and collaborative approaches become essential.

Dr. Zhou's credibility stems from decades of demonstrated results. He has not simply theorized about One Health—he has implemented it successfully at scale. China's malaria elimination, achieved through the systematic application of One Health principles, provides concrete evidence that integrated approaches work. This real-world success gives his advocacy particular weight and demonstrates that One Health is not merely aspirational but practically achievable.

Moreover, Dr. Zhou's emphasis on collaboration and multi-sectoral engagement demonstrates that One Health is not about one group imposing its will on others. Instead, it requires genuine partnership among human health professionals, veterinarians, environmental scientists, policymakers, and community members. This inclusive approach makes One Health more resilient to the kind of polarization that often undermines public health efforts.

In an era when scientific expertise faces scrutiny, champions like Dr. Zhou model what scientific leadership looks like. They demonstrate that rigorous science, collaborative approaches, and practical results can coexist. They show that addressing complex health challenges requires humility about what any single discipline knows, combined with confidence in the power of evidence-based approaches.

Implementing One Health: From Theory to Practice

While One Health sounds compelling in principle, its implementation presents real challenges. Different sectors operate under different regulatory frameworks, funding mechanisms, and professional cultures. A veterinarian and a physician may speak different professional languages despite working on the same disease. Environmental managers may not have formal relationships with health authorities. Overcoming these barriers requires sustained effort, strong leadership, and practical tools.

Technical Innovation and Coordination

Dr. Zhou's work addresses these implementation challenges directly. The development of surveillance systems for malaria elimination required coordination between health facilities, laboratories, and epidemiologists. Spatial epidemiology tools helped identify where transmission was occurring and where interventions needed to be targeted. These technical innovations enabled the kind of coordinated response that One Health principles demand.

The success of these systems demonstrates that One Health implementation is not merely about good intentions—it requires concrete tools, trained personnel, and sustained investment. The surveillance-response systems developed under Dr. Zhou's leadership became a model that other countries could adapt and implement in their own contexts.

Measurement and Accountability

The Global One Health Index provides another practical tool for implementation. By establishing metrics for One Health performance, GOHI helps countries identify their strengths and weaknesses in integrated health approaches. A country might discover that it has excellent human health surveillance but weak animal health monitoring, or strong environmental regulations but poor coordination between environmental and health authorities. These insights enable targeted improvements in One Health implementation.

This measurement approach is crucial because it transforms One Health from an abstract concept into something concrete and measurable. Policymakers and health officials can track progress, allocate resources more effectively, and demonstrate the value of integrated approaches to stakeholders.

Building Workforce Capacity

Capacity building represents another crucial implementation element. Many countries lack the trained workforce necessary to implement One Health approaches effectively. Training programs, educational partnerships, and knowledge-sharing networks help build this capacity. The WFPHA One Health Working Group's focus on capacity building recognizes that sustainable implementation requires investing in people and institutions.

This workforce development is particularly important in low- and middle-income countries, where resources are limited but disease burdens are often highest. By building local capacity, One Health approaches become sustainable and adapted to local contexts rather than imposed from outside.

The Future of One Health and Global Health Security

As the world faces ongoing threats from emerging infectious diseases, antimicrobial resistance, and environmental degradation, One Health approaches will become increasingly essential. The COVID-19 pandemic, which originated as a zoonotic spillover event, demonstrated the catastrophic consequences of failing to apply One Health principles. A more integrated approach to surveillance, research, and response might have identified and contained the virus before it spread globally.

Dr. Zhou's leadership positions him to influence how One Health develops and matures as a field. His work on the Global One Health Index will help establish baselines and track progress in One Health implementation worldwide. His role in WHO expert committees ensures that One Health principles inform international health regulations and recommendations. His capacity-building efforts will help ensure that the next generation of health professionals understands and can implement integrated approaches.

The champions of One Health like Dr. Zhou serve another critical function: they model what scientific leadership looks like in an era of skepticism. They demonstrate that rigorous science, collaborative approaches, and practical results can coexist. They show that addressing complex health challenges requires humility about what any single discipline knows, combined with confidence in the power of evidence-based approaches. They prove that global health challenges can be solved when different sectors work together toward shared objectives.

Looking forward, the expansion of One Health platforms, the refinement of measurement tools like GOHI, and the continued development of integrated surveillance systems will strengthen global health security. Dr. Zhou's work provides a roadmap for how countries can implement these approaches, and his advocacy ensures that One Health remains a priority in global health discussions.
