Oral zinc sulphate solution has a bad taste and therefore children do not accept it easily. This study is required to show that a new formulation of zinc sulphate is better accepted by children. If this is the case, the formulation will improve the management of childhood diarrhoea which is a major cause of morbidity and mortality in Kenya. It is hoped that this study will provide insight on determinants of acceptability and adherence to zinc supplemtantion. This would feed into thee design of interventions that would promote acceptability and eventually reduce the duration and the severity of diarrhoea. If the formulation has a superior acceptability compared to ORS then this would provide insights into the development of better formulations.
