Quadripartite One Health: a renewed regional strategy for Europe and Central Asia
A unified regional response to health threats at the human-animal-environment interface
The WHO, FAO, WOAH (formerly OIE) and UNEP are deepening collaboration through the Quadripartite One Health initiative to tackle threats that cross species and ecosystems across Europe and Central Asia. Rather than isolated, sector-by-sector actions, this approach emphasizes synchronized policy, pooled intelligence and coordinated operational responses to prevent, detect and contain hazards such as zoonotic spillovers, antimicrobial resistance (AMR), food-safety threats and health impacts driven by a changing climate. Covering 53 countries, the strategy seeks to bring ministries of health, agriculture, environment and finance into closer alignment so responses are faster, less redundant and more transparent.
Why a regional One Health platform is urgent now
- Most emerging human pathogens originate in animals: contemporary reviews place the share of new human infectious diseases stemming from animal sources between roughly 60-75%, reinforcing the need for surveillance that bridges species and habitats.
- Antimicrobial resistance is already eroding standard care: recent global analyses estimate over a million deaths each year are attributable to drug-resistant infections, and unchecked AMR threatens both clinical outcomes and economic stability.
- Climate change and land-use transformation are reshaping disease ecology, altering migratory routes and livestock-wildlife contacts, and widening the geographic reach of pests and pathogens.
Taken together, these trends mean that single-country or single-sector systems are insufficient: pathogens, resistance genes and contamination travel along trade routes, across borders and through shared environments. That reality underpins the Quadripartite’s regional emphasis.
The Quadripartite’s strategic pillars and near-term outputs
The partnership organizes activity around integrated, mutually reinforcing pillars that move policy into practice:
- Cross-domain surveillance and laboratory interoperability
- Build linked monitoring systems that fuse human, animal and environmental data to provide near-real-time situational awareness.
- Standardize laboratory protocols and accreditation so test results are comparable and can be rapidly shared across borders and sectors.
- Joint preparedness and rapid-response capacity
- Co-create and exercise shared contingency plans; run multinational simulations so cross-border response teams can mobilize without legal or logistical pauses.
- Set up regional surge assets-personnel rosters, diagnostic kits and emergency stockpiles-that can be dispatched where needed.
- Policy harmonization and legal architecture
- Negotiate interministerial agreements that clarify roles, data-sharing obligations and the thresholds that trigger coordinated action during routine and emergency periods.
- Integrate One Health principles into food-safety law, animal-health regulation and environmental standards to ensure consistent incentives and compliance.
- Workforce development and risk communication
- Roll out cross-sector curricula and certification pathways for One Health practitioners-veterinarians, epidemiologists, environmental scientists and laboratory staff.
- Design unified communication strategies so farmers, clinicians and the public receive the same, evidence-based guidance at the same time.
Subregional priorities: tailoring the framework to local realities
Countries within Europe and Central Asia are adapting the regional roadmap to address distinct risks and capacities:
- Western Balkans: accelerate diagnostics and lab linkages to reduce delays in detecting livestock-associated zoonoses and strengthen veterinary-human health reporting.
- Caucasus: scale surveillance for avian influenza and reduce hazardous poultry handling through farm-level improvements and market reforms.
- Central Asia: integrate AMR monitoring across hospitals and farms and tackle bovine tuberculosis at critical human-animal interfaces.
Operational levers being expanded
Practical actions on the ground are focused on preventing spillovers and stopping onward transmission early:
- Align surveillance across sectors to trace pathogen transmission chains that pass between people, animals and environments.
- Targeted vaccination and enhanced on-farm biosecurity to interrupt transmission along supply chains-examples include poultry vaccination campaigns and fencing and feed-management upgrades to reduce wildlife-livestock contact.
- Strengthened antimicrobial stewardship: curb non-therapeutic antibiotic use in agriculture and standardize clinical prescribing supported by stewardship policies and surveillance of antibiotic consumption.
- Coordinated messaging so veterinarians, farm managers and clinicians act on the same operational guidance during alerts.
Examples from recent years illustrate the stakes: large-scale avian influenza waves in Europe and outbreaks of African swine fever in transboundary pig populations demonstrate how animal diseases can rapidly affect livelihoods and food security, while localized AMR hotspots show the consequences of uncoordinated antibiotic use across sectors.
Financing, governance and the argument for enforceable mechanisms
Experts involved in the regional dialogue caution that voluntary arrangements alone will likely be fragile. Recommended measures include:
- Binding protocols that delineate interministerial duties and set minimum standards for data sharing, outbreak investigation and joint action.
- Dedicated national budget lines for One Health activities, reinforced by multi-year regional and donor funding that is linked to performance and interoperability milestones.
- Contingency mechanisms-such as ring-fenced emergency funds and grant incentives tied to cross-sector collaboration-to maintain continuity beyond short-term projects.
Think of institutionalizing One Health as assembling an interlocking ecological safety net: legal mandates are the fixed posts, predictable financing keeps the net taut, and shared systems create the overlapping meshes that catch gaps before they become failures.
Digital tools and data infrastructures as force multipliers
Technology underpins rapid detection and coordinated response. Priority digital investments include:
- Shared dashboards and scorecards that display outbreak alerts and preparedness metrics for decision-makers in near real time.
- Interoperable laboratory information systems and genomic surveillance pipelines to accelerate pathogen confirmation and source attribution.
- Secure data-exchange platforms that preserve privacy while enabling timely cross-border sharing for public health action.
Emerging capabilities such as pathogen genomics and machine-assisted risk mapping can shorten the time from signal to action-provided countries invest in training, connectivity and governance for sensitive data.
Indicators of a successful regional One Health system
A resilient Quadripartite-enabled region would show measurable gains, for example:
- Shorter detection-to-response times for zoonotic events and coordinated containment that limits geographic spread.
- Declines in inappropriate antibiotic use across human and animal sectors, accompanied by downward trends in resistance markers.
- Regular, multinational simulation exercises and documented joint responses that reduce both economic disruption and human harm from outbreaks.
Persistent challenges to resolve
Key barriers remain: siloed information systems, unequal technical and laboratory capacity between countries, competing budgetary pressures and the political complexity of harmonizing laws across ministries. Overcoming these requires sustained leadership, long-term financing and clear incentives for cooperation.
Moving from vision to routine practice
The Quadripartite One Health framework offers a practical route for countries across Europe and Central Asia to manage shared threats collectively. By integrating surveillance, aligning laboratory standards and response procedures, embedding One Health into legal and fiscal routines, and investing in digital systems and a skilled workforce, the region can substantially reduce the likelihood that localized incidents escalate into regional crises. The real test will be converting high-level commitments into everyday national policies and interoperable operational systems-only then will the promise of One Health deliver measurable protection for people, animals and ecosystems.
