Dispensers for Safe Water

An estimated 315,000 children under the age of five die from diarrhea each year, often as a result of unsafe water. Childhood diarrhea is still the second-leading cause of childhood mortality. Dispensers for Safe Water helps rural communities install a chlorine dispenser directly allowing users to add exactly half a teaspoon of diluted chlorine to a jerry can before filling the can with water. The water stays clean for two to three days. At a cost of $1.28 per person per year (April 2018), Dispensers for Safe Water is a proven, innovative, and cost-effective approach to increase rates of household chlorination.

Deworm the World Initiative

More than 835 million preschool- and school-age children are at risk of parasitic worm infection. The Deworm the World Initiative works with governments around the world to develop and implement national, school-based deworming programs.

This results in treatment coverage of over 200 million children a year, and costs on average less than USD $0.50 cents per child per year, with measurable improvements in health, economic and educational outcomes.
