Editing Diarrhea (section)

Given that water contamination is a major means of transmitting diarrheal disease, efforts to provide clean [[water supply]] and [[improved sanitation]] have the potential to dramatically cut the rate of disease incidence. In fact, it has been proposed that we might expect an 88% reduction in child mortality resulting from diarrheal disease as a result of improved water sanitation and hygiene.<ref name="Brown 629–34"/><ref>{{cite journal | vauthors = Black RE, Morris SS, Bryce J | s2cid = 14509705 | title = Where and why are 10 million children dying every year? | journal = Lancet | volume = 361 | issue = 9376 | pages = 2226–34 | date = June 2003 | pmid = 12842379 | doi = 10.1016/S0140-6736(03)13779-8 }}</ref> Similarly, a meta-analysis of numerous studies on improving water supply and sanitation shows a 22–27% reduction in disease incidence, and a 21–30% reduction in mortality rate associated with diarrheal disease.<ref>{{cite journal | vauthors = Esrey SA, Feachem RG, Hughes JM | title = Interventions for the control of diarrhoeal diseases among young children: improving water supplies and excreta disposal facilities | journal = Bulletin of the World Health Organization | volume = 63 | issue = 4 | pages = 757–72 | year = 1985 | pmid = 3878742 | pmc = 2536385 }}</ref>

Chlorine treatment of water, for example, has been shown to reduce both the risk of diarrheal disease, and of contamination of stored water with diarrheal pathogens.<ref>{{cite journal | vauthors = Arnold BF, Colford JM | title = Treating water with chlorine at point-of-use to improve water quality and reduce child diarrhea in developing countries: a systematic review and meta-analysis | journal = The American Journal of Tropical Medicine and Hygiene | volume = 76 | issue = 2 | pages = 354–64 | date = February 2007 | pmid = 17297049 | doi = 10.4269/ajtmh.2007.76.354 | doi-access = free }}</ref>
