This working paper investigates the long-term effects of a large-scale deworming intervention aimed at primary school pupils in western Kenya. The results show improvements in cognitive performance equivalent to half a year of schooling, as well as a 6% reduction in stunting. Additionally, these results were twice as large for children with an older sibling likely to have received deworming medication directly.

This study investigates the impact of deworming children in rural Tanzania. In the study, children treated for heavy infections of schistosomes and hookworm, benefited more from a teaching session in which they were shown how to solve a reasoning task.

This publication provides a summary of the problem of parasitic worm infections, including the various types of worms and their impact on children’s health and education.

This study helped establish school-based deworming as an efficient investment in human capital by evaluating the economic consequences of the successful eradication of hookworm disease from the American South. A long term follow-up to the hookworm eradication campaign indicated a substantial gain in income in those areas where hookworm infection was eradicated due to treatment. Additionally, adults who were exposed to the treatment campaign as children had higher rates of literacy than those who were persistently infected by worms as children.
