Hookworm prevalence measured by quantitative polymerase chain reaction at sampled schools, stratified by intervention (community-wide MDA or school-based PC) and timepoint (pre- or post-intervention).
MDA = mass drug administration. PC = preventive chemotherapy. Base-layer map provided by the Database of Global Administrative Areas (GADM): https://gadm.org/download_country.html; license: https://gadm.org/license.html.

Moderate-and-heavy intensity Necator americanus infection prevalence at sampled schools, stratified by intervention (community-wide MDA or school-based PC) and timepoint (pre- or post-intervention).
