Population density, sanitation, and health in urban Maputo: the MapSan Trial
Sponsored by USAID’s Translating Research into Action (TRAction) Project
Led jointly by the London School of Hygiene and Tropical Medicine and Georgia Institute of Technology, this project aims to assess the impact of sanitation on a variety of health indicators such as incidence of diarrhea, soil-transmitted helminth infection, and anthropometric measurements, especially among children under five. Researchers from The Water Institute at UNC will design the MapSan Trial, a controlled before-and-after (CBA) study of shared sanitation in urban Maputo, Mozambique. The study evaluates a large-scale, shared sanitary latrine intervention in low-income communities and estimates the impact of sanitary latrine provision on the prevalence of enteric pathogens and environmental exposure to fecal microbes. Participating neighborhoods span a wide range of population densities in order to assess the effect of population density on the relationship between safe sanitation and children’s health. Dr. Stewart leads the analysis of environmental exposures. Researchers will translate the findings to inform policy decisions.
Results from this project could inform efforts to alleviate the burdens of fecal-related disease and environmental exposure to fecal contamination in similar informal, low-income settlements in Sub-Saharan Africa.
