Deworm the
World Initiative

Worm infections lead to anemia and malnourishment. Over 600 million school-age children are at risk of being infected with parasitic worms, but only 35% of them are treated.


Mass treatment at schools is universally recognized as a safe, simple and cost-effective solution.

Deworming impacts education and future health. Rigorous evaluations showed that students in the treatment group have 4% more total years of schooling and 6% higher likelihood of reporting being in “very good” health as young adults.

We help governments begin and grow quality treatment programs at the state and national level: rigorous teacher training, monitoring and reporting. With a total per child cost of less than $0.50 per year, mass school-based deworming is listed as a “best buy” in both education and health.

The Deworm the World Initiative and our government partners served 35 million children last year.
