Billions endure solvable global health crises like parasitic worm infection and unsafe drinking water. Evidence Action specializes in scaling low-cost solutions that are proven to work.
This December, join us in improving the lives of those living in poverty and suffering from preventable or treatable health issues.
All our work is based on rigorous academic evidence, from meta-analyses to randomized controlled trials to research by Nobel Laureate economists.
Every intervention that we bring to scale is designed to deliver outsized impact. Click a program card to learn more.
Deworm the World
We treat parasitic worm infections in one in five children who need it worldwide, for <$0.50 per treatment on average.

Safe Water Now
We provide nearly 10 million people with access to safe water through chlorination, for less than $1.70 per person per year.

Equal Vitamin Access
We’re tackling micronutrient deficiencies in children and laying the foundation for healthy, productive futures for <$0.50 per child, per year.

Syphilis-Free Start
We treat the second leading cause of preventable stillbirths and support healthy pregnancies.
Why Now?
Generous donors have created a pool of matching funds to maximize year-end support for Evidence Action's work. This will match gifts up to $200,000 until December 31.
Your investment supports:
- More babies with syphilis-free starts to life
- More children attending school without fighting anemia or parasitic worm infection
- Access to safe drinking water for more communities in 2026
- Continued innovation and solutions to global health crises via our Accelerator
