Access to safe sanitation in low-income, informal settlements of Sub-Saharan Africa has not significantly improved since 1990. The combination of a high fecal-related disease burden and inadequate infrastructure suggests that investment in expanding sanitation access in densely populated urban slums can yield important public health gains. No rigorous, controlled intervention studies have evaluated the health effects of decentralized (non-sewerage) sanitation in an informal urban setting, despite the role that such technologies will likely play in scaling up access.

This study has designed a controlled, before-and-after (CBA) trial to estimate the health impacts of an urban sanitation intervention in informal neighborhoods of Maputo, Mozambique, including an assessment of whether exposures and health outcomes vary by localized population density. Exposure assessment, fecal source tracking, and microbial transmission modeling will be used to examine whether and how routes of exposure for diarrheagenic pathogens and STHs change following introduction of effective sanitation.
