One Health: Linking Human, Animal and Environmental Health
In short: One Health recognises that the health of people, animals and ecosystems is connected. About 60% of known infectious diseases and around three-quarters of emerging ones come from animals.
Why it matters
Zoonoses such as rabies, avian influenza, Japanese encephalitis, scrub typhus and brucellosis pass between animals and people. Deforestation, intensive farming and wildlife trade increase spillover risk.
Quadripartite approach
FAO, UNEP, WHO and WOAH (the World Organisation for Animal Health) work together under the One Health Joint Plan of Action (2022–2026). Antimicrobial resistance, food safety and zoonotic outbreaks are priority areas.
One Health in Nepal
Rabies from dog bites, bird-flu outbreaks in poultry and scrub typhus are recurring concerns. Joint human–animal investigations, dog vaccination and coordinated surveillance between health and livestock services are practical One Health actions.
Key takeaways
- Most emerging infections come from animals.
- One Health brings human, animal and environmental sectors together.
- Dog vaccination is the most effective rabies prevention.
