Introduction

In an era marked by accelerating zoonotic outbreaks, climate change, and antimicrobial resistance, the boundaries between human, animal, and environmental health are increasingly porous. The One Health paradigm has emerged as a holistic and integrative approach to address these interconnected challenges. It emphasizes the need for collaborative, multisectoral strategies that recognize the interdependence of all living systems. Within this framework, veterinarians occupy a uniquely strategic position—not merely as animal health professionals, but as critical agents of public health, food security, environmental stewardship, and sustainable development.

Historically, veterinary medicine has focused on the diagnosis, treatment, and prevention of diseases in animals. However, the scope of veterinary responsibility has expanded dramatically in response to global health threats. Today’s veterinarians are expected to contribute to pandemic preparedness, monitor wildlife for emerging pathogens, ensure the safety of animal-derived food products, and mitigate the misuse of antimicrobials in livestock systems. Their expertise in disease ecology, pathology, and herd health management makes them indispensable to the operationalization of One Health principles.

Despite this potential, the integration of veterinarians into One Health initiatives remains uneven across regions and sectors. Structural barriers such as institutional silos, limited funding, and underrepresentation in policy-making continue to hinder their full participation. At the same time, emerging technologies, interdisciplinary education, and global health governance reforms offer new avenues for veterinary leadership and innovation.

This essay explores the evolving role of veterinarians within the One Health paradigm, analysing both the challenges that constrain their impact and the opportunities that can elevate their contributions. By examining the intersections of veterinary science with public health, environmental sustainability, and socio-economic development, the discussion aims to underscore the transformative potential of veterinarians in shaping a healthier, more resilient world.

The Expanding Role of Veterinarians in One Health

Veterinarians contribute to One Health through a wide array of functions that extend beyond clinical practice:

1. Zoonotic Disease Surveillance and Control
   • Monitoring animal populations for early signs of emerging pathogens.
   • Investigating outbreaks and implementing containment strategies.
   • Collaborating with human health professionals to track disease transmission.

2. Food Safety and Public Health

• Ensuring hygienic production, processing, and distribution of animal-derived foods.
• Preventing foodborne illnesses through inspection and certification.
• Educating producers and consumers on safe handling practices.

3. Antimicrobial Resistance (AMR) Mitigation

• Promoting responsible use of antibiotics in livestock and companion animals.
• Participating in national AMR action plans and surveillance networks.
• Advising on alternatives to antimicrobials, such as vaccines and probiotics.

4. Environmental and Wildlife Health

• Monitoring wildlife for zoonotic pathogens and ecological stressors.
• Supporting biodiversity conservation and habitat protection.
• Assessing the impact of agricultural practices on ecosystem health.

5. Policy and Advocacy

• Advising governments on animal health legislation and One Health strategies.
• Participating in international platforms such as WOAH, WHO, and FAO.
• Advocating for integrated health systems and interdisciplinary education.

Challenges Faced by Veterinarians in One Health Implementation

While veterinarians are central to the One Health approach, their full integration into its operational framework is hindered by a range of systemic, professional, and socio-political challenges. These barriers not only limit their effectiveness but also compromise the broader goals of One Health in achieving holistic health outcomes across species and ecosystems.

1. Institutional Silos and Fragmented Governance

• One of the most persistent challenges is the lack of structural integration between veterinary, medical, and environmental sectors. Ministries of health, agriculture, and environment often operate in isolation, with minimal cross-sectoral coordination.
• This fragmentation leads to duplicated efforts, delayed responses to zoonotic threats, and missed opportunities for joint surveillance and intervention.
• For example, during outbreaks of diseases like brucellosis or leptospirosis, veterinary data is often underutilized in human health response planning due to poor interoperability between systems.

2. Underrepresentation in Public Health Policy and Decision-Making

• Veterinarians are frequently excluded from national and international health governance platforms, where decisions about disease control, AMR strategies, and pandemic preparedness are made.
• Their absence from key advisory bodies results in policies that overlook animal health dynamics and the role of livestock systems in disease transmission.
• This underrepresentation is particularly acute in low- and middle-income countries, where veterinary public health is not prioritized in budget allocations or strategic planning.

3. Resource Constraints and Infrastructure Gaps

• Many veterinary institutions, especially in rural and underserved regions, lack access to modern diagnostic tools, laboratory facilities, and digital surveillance systems.
• Funding for veterinary public health programs is often limited, with priority given to curative services over preventive and epidemiological functions.
• In dairy systems, for instance, inadequate infrastructure for disease monitoring and milk quality testing can compromise both animal welfare and consumer safety.

4. Workforce Shortages and Skill Gaps

• There is a global shortage of veterinarians trained in public health, epidemiology, and interdisciplinary collaboration. Most veterinary curricula still emphasize clinical practice over systems thinking and policy engagement.
• In rural areas, where zoonotic risks are high due to close human-animal interactions, the scarcity of veterinary professionals exacerbates vulnerabilities.
• Additionally, continuing education opportunities in One Health competencies—such as risk assessment, outbreak investigation, and environmental health—are limited or inaccessible to many practitioners.

5. Limited Data Integration and Surveillance Capacity

• Effective One Health implementation requires real-time data sharing across sectors. However, veterinary data is often siloed in proprietary systems or paper-based records, making integration with human health databases difficult.
• Platforms like India’s NADRS (National Animal Disease Reporting System) and INAPH (Information Network for Animal Productivity and Health) offer promise, but their linkage with human health surveillance remains underdeveloped.
• This disconnects hampers early warning systems and coordinated responses to emerging threats.

6. Public Perception and Professional Identity

• The societal understanding of veterinary roles is often limited to pet care or livestock treatment, overlooking their contributions to public health, food safety, and environmental monitoring.
• This narrow perception affects funding, policy support, and career pathways for veterinarians interested in One Health domains.
• Moreover, the lack of visibility in media and public discourse reduces the perceived urgency of investing in veterinary public health infrastructure.

7. Ethical and Operational Dilemmas

• Veterinarians working in One Health contexts often face ethical tensions, such as balancing animal welfare with public health imperatives (e.g., mass culling during disease outbreaks).
• Operational challenges also arise in conflict zones, wildlife interfaces, and informal livestock markets, where regulatory oversight is weak and risks are high.

Opportunities for Leadership and Innovation

Despite the challenges, the evolving landscape of global health presents veterinarians with unprecedented opportunities to lead, innovate, and reshape the One Health paradigm. Their multidisciplinary training, systems-level thinking, and field-based experience position them to drive transformative change across sectors.
