Deworm the World: Update 2025 | Wealth for the World Evidence Action
New Milestones from Evidence Action – Deworm the World
1.5 billion people worldwide suffer from parasitic worm infections – children are especially affected. Around 895 million children are currently at risk because they lack clean water and sanitation. Since 2014, Evidence Action has provided an evidence‑based answer: one tablet per year reliably protects a child and costs on average less than US $0.50 (Evidence Action 2025) .
Since its founding, Deworm the World has delivered more than two billion treatments; in 2024 alone, 198 million children in India, Kenya, Nigeria, Pakistan and Malawi were reached – a record number (Evidence Action 2025) .
Several innovations are in the spotlight for 2024/25:
Malawi : For the first time, Evidence Action is combining the deworming programme with the Equal Vitamin Access initiative, distributing iron and folic‑acid supplements at the same time (Evidence Action Malawi 2024) .
Kenya : Together with Evidence Action, the government launched the 12th nationwide deworming round , aiming to treat a further six million schoolchildren (Evidence Action Kenia 2024) .
Nigeria : Five states now deworm more than 6 million children annually; since 2016, 28 million treatments have been delivered (Evidence Action Nigeria 2025) .
Funding : A GiveWell‑recommended US $4.4 million renewal grant secures programmes in India, Kenya, Nigeria and Pakistan until 2026 (GiveWell 2024) .
The Problem
Schistosomiasis and soil‑transmitted helminthiasis are classified as “neglected tropical diseases”. Infections lead to anaemia, stunted growth and long‑term income losses. Without regular treatment, children miss up to 25 % more school and, as adults, earn on average 13 % less (Evidence Action 2025) .
The Solution – What Changed in 2024/25
Integration of health services : In Malawi, deworming is combined with iron/folic‑acid distribution through schools, cutting logistics costs and tackling two health issues at once (Evidence Action Malawi 2024) .
Scaling in Nigeria : A single pilot state has grown into a sub‑regional hub with about 40 staff; worm prevalence in Rivers State fell from 43 % (2014) to 13.5 % (2023) (Evidence Action Nigeria 2025) .
Exit strategies & cost reduction : In India and Kenya, Evidence Action is testing remote digital support so that mature programmes can be handed over to governments while costs continue to fall (GiveWell 2024) .
Impact – Current Figures
73 % – 97 % reduction in worm infections in regions served for many years (Evidence Action 2025) .
US $23 billion estimated lifetime productivity gain for children treated so far (Evidence Action 2025) .
In Malawi , over three years 3.5 million children are to be reached, preventing 900 000 cases of anaemia (Evidence Action Malawi 2024) .
The Organisation – Funding & Outlook
Evidence Action follows an evidence‑based scale‑up model : only programmes th
