deworming a stronger vote of confidence, finding that Unlimit Health’s mass treatment programs reached more than 24 million children across Madagascar, Ethiopia and Côte d’Ivoire while remaining highly cost-effective.
The latest backing matters because parasitic worm infections still hit the poorest communities hardest, especially where sanitation is weak and school-age children face repeated exposure. In that setting, low-cost treatment can be delivered at scale through schools and public health systems rather than expensive standalone campaigns.
Deworming review adds weight to an old global health case
According to Unlimit Health’s summary of the new evaluation, the assessment by The Life You Can Save examined the charity’s mass deworming work in three African countries and found especially strong value in reducing schistosomiasis, a parasitic disease that can quietly damage children’s health and learning over time.
That conclusion lines up with the broader public health case. The World Health Organization says soil-transmitted helminth infections affect an estimated 1.5 billion people worldwide and disproportionately burden poor communities with limited access to clean water, sanitation and hygiene.
WHO’s guidance remains straightforward: in places where infection rates are high enough, regular treatment should be part of routine public health practice. Under WHO recommendations on deworming in children, annual or biannual treatment is advised for young children and school-age children living in areas where baseline prevalence reaches at least 20%.
Why the low cost keeps deworming in the conversation
Cost is a big reason deworming keeps resurfacing in global health debates. The Life You Can Save’s charity profile for Unlimit Health says school-based treatment programs generally come in at around 43 cents per child per year, helped by donated medicines and delivery through existing government systems.
The economics look similarly compelling in independent evidence reviews. J-PAL, the Abdul Latif Jameel Poverty Action Lab, notes that deworming can cost about 50 cents per child per year while improving school participation and producing benefits that can last well into adulthood.
That cost structure helps explain why the latest review did not read like a narrow technical update. It reinforced a broader point: when an intervention is cheap, scalable and aimed at a widespread disease burden, even modest gains per child can add up quickly across millions of children.
Deworming has years of evidence behind it
The new review also fits into a longer evidence trail. Back in 2015, the World Economic Forum highlighted research suggesting mass deworming could raise school attendance at very low cost, helping push the issue beyond specialist circles.
Then, in 2020, Harvard Gazette reported on long-run follow-up research from Kenya that found children who received extra years of deworming later had better jobs and higher incomes, giving the intervention a more durable economic narrative.
That does not mean deworming is a complete answer on its own. Lasting progress still depends on cleaner water, better sanitation and stronger local health systems. But the latest Unlimit Health review suggests the treatment itself remains one of the cheaper and more practical tools available while those longer-term fixes are built.
For donors, policymakers and health officials, the takeaway is simple: deworming is not new, but the evidence behind it keeps getting harder to dismiss.
