Welcome Message from the Congress Chairs
It is our pleasure, on behalf of the Global One Health Community, to welcome you to the 9th World One Health Congress in Lisbon (Portugal). This year marks an important milestone, as the World One Health Congress returns to Europe for the first time since the 3rd Congress was held in Amsterdam in 2015. Bringing together the international One Health community in Europe provides a timely opportunity to strengthen international collaboration while highlighting the region's contributions to advancing integrated approaches to human, animal, plant and environmental health. At a time when interconnected health challenges continue to transcend borders, our collective commitment to One Health has never been more important.
As the world's largest gathering dedicated to One Health, this Congress brings together researchers, policymakers, healthcare professionals, veterinarians, environmental scientists, public health experts, industry leaders, international organisations and civil society to exchange knowledge, build partnerships, and shape solutions to the world's most pressing health challenges. The program has been developed with the recommendations and key outcomes of the 8th World One Health Congress in Cape Town (South Africa) firmly in mind, ensuring continuity of discussions while addressing emerging priorities and future opportunities. We have designed a program that promotes scientific excellence, interdisciplinary dialogue and meaningful engagement between science and policy.
The Congress features two complementary abstract-driven tracks: the Scientific Sessions (SCS), showcasing cutting-edge research across the One Health spectrum, and the Science Policy Interface Sessions (SPI), which bridge scientific evidence with policy development and implementation. Complementing these tracks are Workshops, selected through an open call, providing highly interactive opportunities for participants to exchange expertise, develop practical skills and foster collaboration. The program also includes inspiring Plenary Sessions, Partner Sessions, Side Events, and Poster Sessions, where hundreds of peer-reviewed scientific abstracts will be presented, reflecting the breadth, diversity and innovation of the global One Health community.
Supporting the next generation of One Health leaders is one of our core priorities. Through our Early Career Scientists Fund and Low- and Lower-Middle-Income Countries (LMIC) Fund, we are committed to broadening participation and enabling talented researchers from around the world to contribute to and benefit from this global exchange of knowledge. Their ideas, perspectives, and discoveries are essential to advancing One Health for future generations.
We are equally committed to ensuring that the Congress reflects the principles of environmental sustainability. From minimizing single-use plastic and food waste, to making use of a digital program and eliminating any printed material, we continue to implement measures aimed at reducing the environmental impact of the event while encouraging participants to adopt sustainable practices throughout the Congress.
Finally, we extend our sincere gratitude to everyone who has contributed to making this Congress possible. We warmly thank the members of the Scientific Program Committee, the Local Partner Committee, our organizers, reviewers, speakers, supporters, instructional partners, volunteers and the many individuals whose dedication and expertise have shaped this outstanding program.
Dear participants and friends, we wish you all a vibrant, inspiring, interactive and fruitful Congress and thank you for being here to make this 9th edition a great success!
