Purpose
The study is a cluster-randomized, controlled trial conducted among 100 villages (including approximately 3500 households and 20,000 people) in Puri district, State of Orissa, India. The study aims to assess the impact of the construction and use of latrines in rural settings on diarrhoeal disease, helminth infections and nutritional status. The study will also report on the cost and cost-effectiveness of the intervention and its impact on lost days at school and work as well as on expenditures on drugs and medical treatment. The study will document how the intervention actually impacts exposure to human excreta along principal transmission pathways by evaluating the impact on (i) faecal contamination of drinking water, (ii) the presence of mechanical vectors (flies) in food preparation areas, and (iii) the presence of faeces in and around participating households and villages. The study will also explore the extent to which different levels of acquisition and use of on-site sanitation among householders impact disease throughout the community.

Primary Outcome Measures:
- Diarrhoea (<5s) [ Time Frame: 21 months ]Longitudinal prevalence of diarrhoea (7-day period prevalence) measured repeatedly every 3 months over a 21-month follow-up period. Diarrhoea is defined according to the WHO definition (three of more stools passed in 24 hrs)
Secondary Outcome Measures:
- Soil-transmitted helminth infection [ Time Frame: baseline and endline ]Prevalence of soil-transmitted helminth infection at the end of the follow-up period
- Weight-for-age (<5s) [ Time Frame: 21 months ]Weight of children <5 is recorded at each diarrhoea surveillance visit (every 3 months over the 21-month follow-up). Weight-for-age Z (WAZ) scores are calculated using the WHO growth standards. WAZ is used a proxy indicator of recent diarrhoea.
- lost days at school and work [ Time Frame: 21 months ]
- healthcare expenditure [ Time Frame: 21 months ]
- latrine coverage and use [ Time Frame: 21 months ]
- bacteriological water quality [ Time Frame: 21 months ]
- fly counts [ Time Frame: 21 months ]
- Height-for-age [ Time Frame: baseline and endline ]Recumbent length measured for children <2 at baseline and endline following standardised procedures for anthropometric assessment.
- Diarrhoea (all ages) [ Time Frame: 21 months ]Longitudinal prevalence of diarrhoea (7-day period prevalence) measured repeatedly every 3 months over a 21-month follow-up period. Diarrhoea is defined according to the WHO definition (passage of three or more loose stools in 24 hrs).
