Effect of in-line drinking water chlorination at the point of collection on child diarrhoea in urban Bangladesh: a double-blind, cluster-randomised controlled trial

In a Bangladesh trial, chlorine devices were added to water points to combat child diarrhoea. Results showed a reduction from 10% in the control to 7.5% in the treated group. Passive chlorination at collection points could be a viable strategy for safer water in low-income urban areas. Funded by The World Bank.
