At today's Asian Development Bank (ADB) Asia Wolbachia Dialogue, WMP's Peter Ryan joins the panel to share the success of our Wolbachia replacement method, how it's being scaled and the impact it's delivering.

Luciano Moreira brings the Brazil story, showing how that's playing out on the ground.

The move from proven science to government-owned delivery is where the real work happens.

"You do not convince communities - you earn the right to walk alongside them."

Yesterday at the Asia Dengue Summit in Singapore, WMP's Bekti Andari shared what a decade of community engagement across Laos, Indonesia, Vietnam and Timor-Leste has taught us: science alone doesn't stop dengue. Trust does.

Across those programmes, acceptance of our Wolbachia method now runs above 90%.

It's the same approach now taking root with community leaders in Comas, Peru.

"Sometimes people hear the word dengue and think it's nothing - but it can leave you very sick, or even kill you."

Today is World Dengue Day. Meet Alicia, who survived dengue in Peru and now helps her community in Comas understand and accept the Wolbachia method.

Stories like hers are why community engagement sits at the heart of how WMP works with governments to bring Wolbachia to scale.

We're sharing more this week at the Asia Dengue Summit - the team is there all week.

"The mosquito doesn't waste any time - it finds the perfect place to lay its eggs."

In the hills of Comas, Peru, community leader Carmen Luz Estrella Paz turned dengue prevention into her mission, moving her neighbours from doubt to belief in the Wolbachia method. Her conviction is simple: "Wolbachia is important - it will save lives."

This is the community leadership that makes public health work at scale.

Next Monday, 15 June, is World Dengue Day - we'll be sharing more stories like Carmen's through the week, so keep an eye out.

Dengue costs more than most people see: hospital bills, lost days of work, overwhelmed health systems. New research asked whether preventing it is worth the investment.

Earlier this week, we shared evidence on how effectively Wolbachia-based dengue control reduces dengue. Today's paper addresses the other side of the question.

Beyond the illness itself, there are hospital bills, days lost from work, and the strain placed on health systems each time an outbreak hits. For families in dengue-endemic communities, this burden is ongoing.

Nine independent economic studies across seven countries consistently found the intervention cost-effective in high-burden urban settings. In many, the societal benefits are projected to outweigh programme costs entirely.

Protecting communities from dengue makes both ethical and economic sense.

More than 21,600 households across 22 villages in Savannakhet Province are now part of the effort to drive down dengue in Laos.

Here is how it works. Wolbachia is a natural bacterium found in many insects. When mosquitoes carry it, the viruses that cause dengue find it much harder to grow inside them, which helps reduce the spread of dengue to people. The method is self-sustaining and is already helping to protect communities in countries around the world.

We are so proud of what we are achieving in Laos, and hugely grateful to the Save the Children in Laos team and the Department of Communicable Disease Control, along with the local communities, volunteers, and youth champions who have welcomed this work and made it their own.

This project is supported by the Australian Government through the Partnerships for a Healthy Region initiative.

Across more than 8 million people, in communities across three continents, the story is consistent.

A new systematic review brought together nine studies of Wolbachia-based dengue control, covering populations in Southeast Asia, South America, and Australia. Where Wolbachia-infected mosquitoes have been deployed, dengue incidence has fallen across all studies reviewed.

City-wide deployments showed the largest reductions. The broader the coverage, the greater the benefit to the community.

Systematic reviews rigorously synthesise findings and assess the quality of each study included, making them one of the most reliable ways to evaluate whether an approach works across different settings and contexts.

This review adds to the evidence that Wolbachia-based approaches are an effective tool in the global effort to protect communities from dengue.

Our animated film, Releasing Hope, has had quite a week. 🎬

It has won Best Directed Animated Film at the LA Film and Documentary Awards, been nominated at the Cannes Film Awards, and shortlisted at the Prolific North Creative Awards.

The film tells the story of our Wolbachia method and the communities it's helping to protect from mosquito-borne diseases. To see it being recognised like this means a lot - we hope it helps even more people discover what is possible.

Huge thanks to director Karl Doran, the team at FLOW Creative, and our own Bruno Col and Alex Jackson. The score was composed and performed by Efterklang.

From Rio de Janeiro to Brumadinho, our Wolbachia method is spreading across Brazil.

More than six million people in 29 cities are already protected from dengue, Zika, and chikungunya, and a new five-year project in the Paraopeba River Basin will reach another 1.1 million.
