Treatments for parasitic worm infections (deworming)
OVERVIEW
Hundreds of millions of people around the world are infected with parasitic worms.(14) This program provides children with medication that clears parasitic infections and may lead to a large increase in lifetime earnings. We recommend the program based on its small potential for a large impact on earnings.
COST-EFFECTIVENESS
Donating $100 will deworm about 100 children,(15) leading to a cumulative $1,100 in additional earnings over the course of the children's lives.(16) This program is implemented in areas where people on average live on $700 per year.(17) This is significantly more cost-effective than cash transfers.
Compare to most charities’ programs
EVIDENCE OF IMPACT
Strong. Many high-quality studies show that treating children clears worm infections. One trial and several follow-up studies show a large increase in participants’ lifetime earnings. The organizations we recommend conduct high-quality ongoing monitoring.
