This article summarises the findings from the cost-effectiveness component of a study which investigated the impact of three different household water treatment approaches on the treatment of severe acute malnutrition (SAM).

The study found that the addition of a chlorine or flocculent disinfection point-of-use drinking water intervention to the treatment of SAM reduced the cost per child recovered compared to standard SAM treatment. The findings from the principle aspect of the study – the effectiveness of water treatment technologies on SAM recovery – can be found in a previous article.
