Dear Colleagues and Partners in Global Health,

On behalf of the Medical Association of Thailand (MAT), it is my great honor and privilege—as both the President of the Medical Association of Thailand and the President of the 4^th One Health International Conference (4^th OHIC Bangkok 2026)—to warmly invite you to join us in Bangkok on December 3^rd–4^th, 2026, at the Centara Grand at Central Plaza Ladprao, for this landmark event.

This year’s OHIC theme centers on strengthening intersectoral collaboration to address some of the most pressing global health challenges under the One Health approach. The conference will feature high-level keynote speakers, expert panels, and cross-disciplinary discussions in the following key areas:

• Food Safety and Security
• Disaster Management and Preparedness
• One Health Education and Workforce Development
• Open Topics in One Health, including environmental health, antimicrobial resistance, zoonoses, and more.

As we face increasingly complex health threats at the human-animal-environment interface, we must come together to share knowledge, build partnerships, and shape policies that safeguard global health.

We look forward to welcoming academics, practitioners, policymakers, and students from around the world to engage in meaningful dialogue and innovation at 4^th OHIC 2026 in vibrant Bangkok.

Warm regards,

Organized under the auspices of the Medical Association of Thailand (MAT), this landmark gathering will bring together distinguished experts and stakeholders from across the globe under the unifying framework of One Health.

This year’s program will spotlight the vital role of cross-sectoral collaboration in four key domains:

It is with genuine delight that we welcome academics, healthcare professionals, policymakers, and students from around the world to engage in meaningful dialogue, cultivate enduring partnerships, and strengthen global health—united at the 4^th OHIC 2026 in vibrant Bangkok.
