Introduction
December 2025 concludes a year of growing global collaboration across the human, animal, and environmental health sectors. Around the world, One Health conferences will foster partnerships. These events bridge science, policy, and community resilience.
As climate pressures and new diseases reshape global health, these conferences provide an ideal setting for experts to share research and coordinate prevention strategies. They also strengthen One Health systems for the decade ahead. These events are more than meetings—they are spaces for sharing evidence, learning from global experience, and identifying practical ways to protect health across species and environments.
Will you be part of the discussions that define One Health in 2026 and beyond?
