How does the One Health framework provide structural policy support for animal health market growth?
The One Health framework — jointly adopted by WHO, FAO, UNEP, and WOAH — recognises that 60% of human infectious diseases originate in animals, that antimicrobial resistance crosses species boundaries, and that food system health is inseparable from animal health. This framework creates structured government investment in veterinary surveillance, emergency animal health response, AMR stewardship, and food safety — sustaining public-sector animal health procurement that grows with disease emergence events independent of commercial market cycles.

Asia-Pacific now represents the fastest-growing regional animal health market — growing above the global 11.5% CAGR — as both companion animal and livestock market development compound simultaneously.
