With funding from the UK Department for International Development (DFID) and the Bill & Melinda Gates Foundation (BMGF), we are conducting a randomized, controlled field trial among 100 villages Odisha, India to assess the health impact of rural sanitation under the Government of India’s Total Sanitation Campaign. Health outcomes include diarrheal disease, soil-transmitted helminth infection and nutritional status. The study also includes extensive assessments of program delivery, sanitation coverage and use, and impact on major transmission pathways of exposure.
As lead collaborators with the World Health Organization in the development of the first Guidelines for Sanitation and Health, we are responsible for providing the evidence base for the effectiveness of sanitation interventions in reaching targeted populations, securing their adoption and sustained use, mitigating exposure and preventing diseases associated with poor sanitation.
In a large scale randomized, controlled trial in Western Province, Rwanda, we are assessing the impact of a program financed by carbon credits that provides advanced water filters and improved cook stoves to the lowest income households. Health outcomes include diarrhea, respiratory infection, hypertension and biomarkers of disease and exposure. The study includes monitoring of personal level exposure to carbon monoxide and PM 2.5 as well as drinking water quality.
To assess the impact of a new filter that includes arsenic adsorption, we are conducting a randomized, controlled trial in West Bengal, India. The study will investigate the impact of the filter on both arsenic levels in drinking water and urinary arsenic loads of members of participating households.
