One Health Summit 2026

The One Health Summit will take place from april 5 to 7, 2026, in Lyon, France.

From 05 to 07 April 2026

Main points

  • The One Health Summit, the ninth edition of the One Planet Summits, will contribute to the French G7 Presidency in 2026.
  • The Summit aims to strengthen international cooperation in response to health, food and environmental risks through the implementation of the One Health approach.
  • On this occasion, ANRS Emerging Infectious Diseases (ANRS MIE) will partner with the event “Youth Challenges the World” and will co-organise three events that have been awarded the “One Health Festival” label.

One Planet, One Health : Youth taking Action

For younger generations, health, environmental and social crises are their immediate horizon. This event, which contributes directly to the Summit and is coordinated by the French National Research Institute for Sustainable Development (IRD) with its partners, will bring together around one hundred young adults aged 18 to 35, who are leading initiatives and proposing new visions to address One Health challenges.

Coming from all five continents, they are researchers, entrepreneurs, and actors from the non-profit and innovation sectors. This international mobilisation will help bring forward a collective youth voice, structured around concrete, action-oriented recommendations aimed at informing international discussions and engaging decision-makers during the Summit.

Youth taking action – One planet, one health : one generation in action

The event will take place on 6 April 2026, from 3:00 p.m. to 6:00 p.m.

ANRS MIE takes part in the One Health Festival

On the occasion of the Summit, and in order to highlight One Health initiatives in France and internationally, a call for proposals was launched to select events awarded the One Health Festival label. In this context, ANRS MIE and its partners will present three events.

One Health and pathogen families : R&D roadmaps for resilience and equity in global health Security and pandemic response

ANRS MIE, the Coalition for Epidemic Preparedness Innovations (CEPI) and the World Health Organization (WHO), in collaboration with the Infectious Diseases Cluster (IDCluster), are pleased to invite you on 7 April 2026, in Lyon, from 8:00 a.m. to 9:00 a.m.

Emerging infectious diseases remain one of the most significant global risks. As the majority of them (75%) are zoonotic in origin, this highlights the essential role of One Health approaches. Since it is impossible to predict which pathogen may cause the next pandemic, strengthening preparedness requires coordinated, cross-disciplinary action, while ensuring equitable access to resources and solutions.

WHO’s Collaborative Open Research Consortia (CORCs) serve as key platforms for designing and implementing research and development (R&D) roadmaps aimed at developing medical countermeasures against priority pathogens and pathogen families. They provide a structured and comprehensive framework, from concept through to implementation. This event will mark the launch and presentation of how the One Health approach has been integrated into R&D roadmaps focusing on viral and bacterial families. These include, in particular, work led by ANRS MIE on the Filoviridae family, which includes Ebola virus and other highly lethal viruses, work conducted by Fiocruz (Brazil) on flaviviruses, and work by the UK Health Security Agency on phenuiviruses.

CEPI will also highlight its catalytic role as an implementation partner for CORC roadmaps and in advancing critical R&D efforts to develop vaccines against future threats, both known and unknown. By promoting an approach based on entire viral families, global distributed networks of laboratories, clinical trials and vaccine manufacturing, as well as local and regional capacities linked to the 100 Days Mission, CEPI will demonstrate how research priorities defined by CORCs can be translated into concrete preparedness actions, supporting the global ambition to respond to future epidemic and pandemic threats within 100 days.

Programme:

  • Welcome and opening
  • One Health and pathogen families: R&D roadmaps for resilience and equity in global health security and pandemic response
  • Overview presentation by the WHO R&D Blueprint for Epidemics
  • Roundtable with CORC leads
  • Integrating the One Health approach into R&D for medical countermeasures: ongoing global and regional initiatives
  • Q&A
  • Conclusion
Registration for virtual participants

One Health: Multiple Solutions for the Prevention, Control and Elimination of Vector-Borne Diseases

ANRS MIE, IRD and the University of Montpellier are pleased to invite you on 9 April 2026, in Montpellier, from 2:00 p.m. to 6:00 p.m.

This conference will bring together scientists, public decision-makers, international organisations and civil society stakeholders to discuss innovative and sustainable solutions to combat vector-borne diseases, within an integrated One Health approach linking human, animal and environmental health.

Programme:

  • Institutional opening
  • Musical and video performances
  • Overview of available solutions and their impacts
  • Roundtable: feedback on the implementation of One Health solutions (real-world settings / research projects) – success factors, challenges and contributions of the One Health approach
  • Conclusion

The conference will feature videos and musical performances showcasing research and field initiatives, and will be followed by a cocktail reception (6:30 p.m. – 8:00 p.m.).

2nd Brazil–France Workshop on Arboviruses: Strengthening Global Arbovirus Preparedness and Response through Scientific Collaboration

ANRS MIE and the Evandro Chagas Institute are pleased to invite you on 9 and 10 April 2026, in Belém, Brazil.

In a context of rapid expansion of arboviral diseases, strengthening international scientific cooperation is a priority, particularly in the Amazon region, where climate change, environmental transformations and social vulnerabilities intersect. Building on the first France-Brazil workshop on arboviruses held in Belém in 2024, this second edition, co-organised by ANRS Emerging Infectious Diseases and the Evandro Chagas Institute, aims to consolidate Franco-Brazilian research collaborations on arboviruses, in line with the priorities of COP30 and within the framework of the PRISME France-Brazil initiative.

The workshop is grounded in a One Health approach. Arbovirus transmission results from interactions between human populations, vectors and the environment. In the Amazon, rising temperatures, changing precipitation patterns and deforestation are reshaping vector distribution and seasonality, as well as viral adaptation. At the same time, in Europe, France, including its overseas territories—is experiencing an increase in cases linked to the spread of Aedes mosquitoes, highlighting the interconnected nature of these threats.

By bringing together experts in epidemiology, entomology, genomics, environmental surveillance and social sciences, the event fosters a transdisciplinary dialogue and, through an interactive format, aims to generate cross-border research projects on the climatic, ecological and societal determinants of arboviral emergence.
