Extended burden of disease estimates related to WSH

All together, improvements related to drinking-water, sanitation, hygiene, and water resource management could result in the reduction of almost 10% of the total burden of disease worldwide.

In addition to diarrhoea, an important share of the following diseases could be prevented if adequate water quality and quantity, sanitation facilities, hygiene behaviour, as well as water resource management interventions were implemented:

  • Malnutrition
  • Intestinal nematode infections
  • Lymphatic filariasis
  • Trachoma
  • Schistosomiasis
  • Malaria
  • Other infectious diseases
  • Deaths and DALYs estimates attributable to WSH, by country and by region, 2004

    Theses disease burden estimates are based on a combination of comparative risk assessment methods, evidence synthesis and expert estimates. The scientific rigor of the estimates based on expert opinion is not of the same level as that of the estimates based on comparative risk assessment methods; these estimates are therefore not formal WHO estimates, but nevertheless are the best ones currently available.
