In the complex world of education policy, some experts comment that school-based deworming may be the closest we have come to finding a "magic bullet." In regions of the world with high worm burdens, such as Africa and South Asia, deworming children for mere pennies a year results in an incredible range of educational and social benefits, from higher school attendance rates to healthier children who are better able to learn in the classroom.
Globally, more than 1 in 4 people are infected by intestinal worms. In Sub-Saharan Africa high infection rates prevail, particularly among school children. Worms can cause anemia, stunting, lethargy and other problems that derail children's development. The positive impact of deworming on both health and educational outcomes is routinely cited as an example of aid effectiveness, including by Nicholas Kristof in the recent column “Getting Smart on Aid,” in the New York Times. Schools are also the best delivery mechanism for reaching children with safe, mass treatments.
While deworming has proven to be one of the most cost-effective interventions to get children into school, promising new research suggests that deworming children can also result in many long-term benefits, including higher wages, healthier individuals and stronger communities. The World Bank hosted a special panel on Rethinking Deworming this month, featuring guest speaker Michael Kremer, co-Founder of Deworm the World and Gates Professor of Economics at Harvard, who presented the new research findings of a study in Kenya.
