What began as ASEAN Dengue Day has grown into a truly global mobilisation. Today, more than half the world's population lives at risk of dengue, a disease spreading faster than ever, fuelled by climate change, urbanisation, and human mobility. Reported cases have grown from around 500,000 at the turn of the century to 14.6 million in 2024 alone.

As a network of 32 institutes across 25 countries, we believe science closest to the ground makes the biggest difference. That is why today, a large majority of our members are taking to social media to share their work, their expertise, and their commitment against dengue.

As the President of the Pasteur Network Mario Moreira puts it: "Dengue does not follow borders. It follows the climate, the mosquito, and the movement of people. The Pasteur Network's strength has always been its proximity to affected communities: researchers embedded in the territories most impacted, working side by side with local actors and drawing on the knowledge and realities of those communities. That proximity is what makes the difference between data and decisions, between research and real public health impact."

What the Pasteur Network is doing:

 Collective Action on Dengue (CAD) — a global multisectoral platform to align dengue strategies with climate and urban health agendas  Climate & Health Observatory Accelerator — supporting 18 fellows in 16 countries to integrate climate and dengue data into public health systems  DURABLE — building outbreak preparedness and response capacities across partner institutions  PREZODE — a One Health framework for pandemic prevention at the human-animal-environment interface  Pasteur Network Scientific Convening: Arboviruses in Focus — Spotlight on Dengue — a meeting at Sciensano (Brussels), June 25, 2026
