Millions of people globally do not have access to safe drinking-water, sanitation and hygiene (WASH) services and consequently suffer from or are exposed to a multitude of preventable illnesses. Unsafe WASH is associated with infectious diseases, health risks from exposure to chemicals and other contaminants in drinking-water, as well as impacts on well-being. WHO estimates the burden of disease attributable to unsafe WASH for key health outcomes and report on SDG indicator 3.9.2.

 

Mortality
1.4 million
deaths* could have been prevented with safe WASH in 2019
Morbidity
74 million
DALYs* could have been prevented with safe WASH in 2019
Attributable fraction
69%
of all diarrhoea deaths in 2019 were attributed to unsafe WASH services
Diarrhoea deaths
>1 million
died from diarrhoea due to unsafe WASH in 2019
Acute respiratory infections deaths
356 000
died from acute respiratory infections due to unsafe hand hygiene practices in 2019

*from four health outcomes included under SDG indicator 3.9.2 estimations (diarrhoea, acute respiratory infections, soil-transmitted helminthiases, undernutrition).
