*********************************
There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Summaries

Summary Sentence: Joe Brown, Georgia Institute of Technology

Full Summary: Abstract:Introduction: Access to safe sanitation in low-income, informal settlements of Sub-Saharan Africa has not significantly improved since 1990. The combination of a high faecal-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 decentralised (non-sewerage) sanitation in an informal urban setting, despite the role that such technologies will likely play in scaling up access.Methods and analysis: We have designed a controlled, before-and-after (CBA) trial to estimate the health impacts of an urban sanitation intervention in informal neighbourhoods of Maputo, Mozambique, including an assessment of whether exposures and health outcomes vary by localised population density. The intervention consists of private pour-flush latrines (to septic tank) shared by multiple households in compounds or household clusters. We will measure objective health outcomes in approximately 760 children (380 children with household access to interventions, 380 matched controls using existing shared private latrines in poor sanitary conditions), at 2 time points: immediately before the intervention and at follow-up after 12 months. The primary outcome is combined prevalence of selected enteric infections among children under 5 years of age. Secondary outcome measures include soil-transmitted helminth (STH) reinfection in children following baseline deworming and prevalence of reported diarrhoeal disease. We will use exposure assessment, faecal source tracking, and microbial transmission modelling to examine whether and how routes of exposure for diarrhoeagenic pathogens and STHs change following introduction of effective sanitation.About the Speaker:Joe Brown is an assistant professor in environmental engineering.  Brown comes to Georgia Tech from the London School of Hygiene and Tropical Medicine, where he served as a lecturer in the Department of Disease Control, Faculty of Infectious and Tropical Diseases.  Brown’s research and teaching interests are at the intersection of environmental engineering and public health, including water infrastructure sustainability, detection methods for pathogens and pathogen indicators in the environment, water treatment technology characterization and innovation, and human health effects of exposure to waterborne pathogens.  His globally focused work currently spans four continents including active research projects in Cambodia, Zambia, Tanzania, Malawi, Pakistan, India, the United Kingdom, and the Southeastern USA.  He serves as PI on a USAID-funded project to study health impacts of urban sanitation expansion in Mozambique.  He is a Professional Engineer (PE) with licensure in North Carolina and Alabama.
