Half of the world’s population still does not have adequate access to safe drinking water, sanitation and hygiene (WASH) which could have prevented at least 1.4 million deaths and 74 million disability-adjusted life years in 2019, according to this latest report by the World Health Organization (WHO).

The report summarizes the estimates of the burden of disease attributable to unsafe drinking water, sanitation, and hygiene for the year 2019 for four health outcomes - diarrhoea, acute respiratory infections, soil-transmitted helminthiases, and undernutrition - which are included in the reporting of the Sustainable Development Goal indicator 3.9.2. The report includes estimates at global, regional and country level for 183 WHO Member States.
