In areas where diarrhoeal disease is common, do interventions that aim to improve the quality of drinking water prevent diarrhoea? Evidence Update, Diarrhoea Series, January 2007.
Each Evidence Update is a 2-page summary of a Cochrane Review of healthcare interventions relevant to people in low-income and middle-income countries.
This Evidence Udate is adapted from Clasen T, Roberts I, Rabie T, Schmidt W, Cairncross S. Interventions to improve water quality for preventing diarrhoea. Cochrane Database of Systematic Reviews 2006, Issue 3. Art. No.: CD004794. DOI: 10.1002/14651858.CD004794.pub2.
Researchers have tested a range of interventions applied at the water source, and at the point of use. Those tested all helped reduce diarrhoea in all age groups.
