Fast facts

  • Sightsavers’ deworming programme was a GiveWell top charity from 2016-2022, until GiveWell updated its criteria. GiveWell’s previous reviews, blog posts, and conversation notes from its evaluations of Sightsavers’ deworming programme can be found here.
  • Open Philanthropy has awarded several grants to Sightsavers’ deworming programme, including over $4 million USD in Ocober 2021 and $9 million USD in 2019.
  • In 2021, Sightsavers reported helping to provide over 26 million schistosomiasis treatments and treating over 11 million people for intestinal worms.
  • Sightsavers reports that worms can cause a variety of health problems, including nutritional issues, problems with cognitive and physical development, and even death. The organisation explains that worm infections can also affect social and economic outcomes like employment and school attendance, and that schistosomiasis can “lead to serious long-term problems affecting the digestive, urinary, respiratory and nervous systems.”
  • Some research shows that deworming has positive effects on school attendance, income earnings, and economic growth. There is also some uncertainty surrounding findings that link deworming programmes to improved life outcomes — see GiveWell’s in-depth look.
  • GiveWell estimates deworming to be “highly cost-effective” and states that it “expect[s] to continue supporting deworming through grants from our All Grants Fund, as there continue to be funding opportunities in deworming that exceed our cost-effectiveness threshold.”
