Understanding One Health Post-COVID
Introduction
The concept of One Health draws attention to the interconnectedness of humans, animals, and the environment. The 1995 film "Outbreak" presciently illustrated such interconnected crises, with parallels to the COVID-19 pandemic.
Development of the One Health Concept
- The term One Health was first officially used in 2003-2004, linked to the emergence of severe acute respiratory syndrome (SARS).
- The Manhattan Principles of 2004 emphasized the connection between human and animal health.
- Primary drivers of zoonotic diseases include human activities like ecosystem changes and urbanization.
Global Response to Health Crises
The COVID-19 pandemic underscored the necessity for a unified global health approach. The WHO Pandemic Agreement of May 2025 is a legally binding treaty aimed at improving global pandemic response.
International Collaboration
- Internationally led by the Quadripartite collaboration: WHO, FAO, UNEP, and the World Organisation for Animal Health.
- Launched the One Health Joint Plan of Action in October 2022.
India's Initiatives
Post-COVID, India expedited efforts to integrate human, animal, and environmental health sectors through the National One Health Mission, aimed at enhancing pandemic preparedness and disease control.
State-led Innovations in India
- Odisha's Climate Budget for climate-resilient development.
- Kerala's participatory carbon-neutral plan in Meenangadi.
- Tamil Nadu's Green Climate Company and Cool Roof Project in Chennai.
Current Discussions and Expectations
The One Health Summit in Lyon, France, focuses on contributors to global health challenges, including zoonotic diseases, AMR, and sustainable food systems. The summit aims to foster interdisciplinary dialogues and propose solutions.
