WASH-related disease burden estimation tool

Overview

This tool enables estimation of deaths, DALYs, and mortality rate from diarrhea, acute respiratory infections, protein-energy malnutrition and soil-transmitted helminthiases, attributable to inadequate drinking water, sanitation, and/or hygiene. These corresponds to the health outcomes included to report on SDG indicator 3.9.2.

The methods underlying calculations in this spreadsheet are similar to those used by WHO for the global analysis of burden of disease attributable to unsafe WASH. The user can construct scenarios and compare health impacts from different water, sanitation, hygiene or combined WASH exposures.

The scenarios can cover communities, cities or entire countries, and different years, provided the required disease and exposure data are available at those levels.
