World Health Day · April 7, 2026

Together for Health, Stand with Science

This year's World Health Day calls on the world to stand with science — to champion the evidence, collaboration, and commitment it takes to turn research into real health gains.

That's exactly what your support makes possible. These aren't experiments — they're proven interventions reaching millions, delivered through government systems built to last.

Here's a look at updates and progress from the first quarter of 2026.

Deworm the World

After USAID's exit, Tanzania chose the harder path — and sought the support of Evidence Action to navigate it

Cyclist Tom visits Evidence Action deworming programs

A cyclist fundraising to reach over 38,000 children, and a firsthand look at National Deworming Day

German cyclist Tom biked across continents raising thousands for Evidence Action. He arrived in India just in time for National Deworming Day — to see $0.50 treatments and a system designed to reach every child.

In the New York Times: Five hours of war spending could deworm every child who needs it Nicholas Kristof calculates that for less than $400 million, every at-risk child worldwide could be dewormed. Evidence Action was cited by name.
Safe Water Now
We found errors in our dispensers monitoring. Here's what we're doing about it. Independent evaluation revealed 70% fewer people using our dispensers than estimated. We're scaling back and redirecting resources — and publishing our analysis.

"That kind of collaboration, that willingness and desire to be transparent, even when the news might not be good, that is not something that you should take for granted. That's extremely rare in the nonprofit world. And we are extremely grateful to Evidence Action, and to other organizations that we work with, that they engage with us in that way."

India connected 150 million homes to tap water. Now comes the hard part: making it safe to drink. A new national partnership with India to strengthen chlorination across rural water systems — turning water access into water quality.
Women behind Safe Water Now — engineers, health workers, and mothers

Syphilis-Free Start
Maternal syphilis screening at antenatal clinic, Zambia

Zambia

Zambia went from 45% to 90% screening — and uncovered twice the infections anyone expected

Syphilis prevalence among pregnant women is more than double previous estimates — tens of thousands more babies at risk, and more opportunities to intervene.

The test that screens for both HIV and syphilis just dropped to $0.84 — pennies more than HIV-only Adding syphilis screening to existing prenatal care now costs almost nothing. In Liberia, it took screening from 8% to 88% and saved over 1,000 lives.
Equal Vitamin Access

From the Field

A weekly dose that fights childhood anemia — and the health worker delivering it door to door

In Jharkhand, health worker Sarita Devi faced rumors and closed doors. But iron syrup reduces childhood anemia risk by 30% — so she kept showing up. Now the parents who turned her away remind neighbors when it's time for the next dose.

Accelerator

826 million people can't see up close — and a $1 pair of glasses could change that

Nigeria · MMS Trial

Our prenatal vitamin trial is scaling up — and the numbers make the case

Over the next few years, we expect to reach nearly 1 million pregnant women with multiple micronutrient supplements, preventing 12,000 anemia cases.

AI Access Initiative

Evidence Action incubates AI for Good initiative, publishes cross-sector analysis The AI Access Initiative — incubated at Evidence Action — evaluated 30+ AI interventions for their potential to reach the 3.5 billion people living in poverty globally. Developed with guidance from Nobel Laureate Michael Kremer, Anthropic CEO Dario Amodei, and Kent Walker of Google.
Devex: Why AI for good still isn't scaling — and a new effort to fix it Despite surging interest and investment, most AI for good efforts remain stuck in disconnected pilots. The AI Access Initiative is designed to change that, coordinating across labs, governments, funders, and delivery partners to move from pilots to population-level impact.
Devex podcast: Can a new effort scale AI for good to reach hundreds of millions? Kanika Bahl on "Global Progress in the AI Era": how fragmented pilots become population-level outcomes, and why 2026 is a building year for the AI Access Initiative.

Every update above represents a proven solution scaled through government systems designed to last. Your support makes the next one possible.
