The Department of Environmental Health in the Ministry of Public Health and Sanitation maintains a database on latrine coverage beginning from July 2008, when a baseline survey had been conducted. Data on monthly latrine coverage in 2009 was extracted from this database. Data on outpatient diarrhoeal morbidity among children under 5 years for 2009 was provided by the district health records office. These records indicate the number of diarrhoeal cases treated per month in health facilities within the district.
