Meaning
- One Health is an integrated approach that recognises the interconnectedness of human health, animal health, and environmental health
- It promotes coordinated action across medical, veterinary, ecological, and public health sectors
- The approach focuses on preventing, detecting, and responding to health threats that arise at the human–animal–environment interface
Core Pillars of the One Health Approach
- Human Health
- Disease surveillance, diagnosis, treatment, and public health preparedness
- Animal Health
- Veterinary services, livestock vaccination, wildlife monitoring, and biosecurity
- Environmental Health
- Ecosystem protection, pollution control, waste management, and climate resilience
Operational Mechanisms
- Integrated disease surveillance systems linking human and animal health data
- Mass vaccination programmes in livestock and companion animals
- Monitoring of wildlife disease reservoirs and spillover risks
- Regulation of veterinary drugs to curb antimicrobial resistance
- Safe disposal of animal carcasses and biomedical waste
- Data-sharing platforms for early warning and outbreak response
Importance of the One Health Approach
- Zoonotic Disease Control
- Enables early detection and containment of diseases such as Nipah, avian influenza, rabies, and coronaviruses
- Food and Nutrition Security
- Reduces losses in livestock and poultry caused by disease outbreaks
- Pandemic Preparedness
- Strengthens coordinated response mechanisms before outbreaks escalate
- Environmental Protection
- Addresses pollution, biodiversity loss, and ecosystem disruption that contribute to disease emergence
- Antimicrobial Resistance Management
- Promotes responsible use of antibiotics across sectors
- Climate Change Adaptation
- Helps track climate-sensitive vectors and pathogens
Global Institutional Framework
- The One Health framework is jointly supported by
- World Health Organization
- Food and Agriculture Organization
- United Nations Environment Programme
- World Organisation for Animal Health
- These institutions launched a Joint Plan of Action to enhance global coordination, capacity building, and policy coherence
One Health in the Indian Context
- India has institutionalised the approach through a National One Health Mission
- The mission focuses on
- Strengthening zoonotic disease surveillance
- Enhancing laboratory networks
- Improving coordination between health, animal husbandry, and environmental agencies
- Addressing antimicrobial resistance through a multisectoral strategy
Structural Challenges
- Fragmented governance with limited coordination between departments
- Uneven investment in animal and environmental health infrastructure
- Inadequate diagnostic and laboratory capacity in rural areas
- Data silos and weak interoperability across surveillance systems
- Community resistance, misinformation, and low awareness
- Climate variability expanding disease vectors into new regions
Strategic Way Forward
- Strengthening inter-ministerial coordination through empowered leadership
- Expanding animal vaccination and wildlife monitoring programmes
- Establishing district-level integrated zoonotic disease laboratories
- Building national digital surveillance platforms using GIS and AI tools
- Implementing a robust antimicrobial stewardship framework
- Enhancing community participation and risk communication
