Intervention Description

The World Health Organization currently recommends that school children in endemic areas are regularly treated with drugs which kill these worms. The recommended drugs are effective at eliminating or greatly reducing worm infections, but the question remains whether doing so will reduce anaemia and improve growth, and consequently improve school attendance, school performance, and economic development, as has been claimed. Main intervention involved treatment with multiple doses of deworming drugs.

Approaches and Outcomes

  • Deworming / Improved critical thinking
  • Deworming / Increased test scores
  • Deworming / Reduced absenteeism
