About 5.3 million children under the age of five died in 20181. Most of these deaths occurred in lowincome countries, with the highest risk of death in sub-Saharan Africa (69 deaths per 1000 live births). Sustainable Development Goal (SDG) 3 aims to end all preventable deaths of newborns and children under the age of five by 2030, with all countries aiming to reduce under-five mortality to at least as low as 25 deaths per 1000 live births. In contrast, 2018 estimates of child mortality for sub-Saharan Africa stand
at 78 per 1000 live births. There is a need to identify simple, feasible and cost-effective interventions to reduce child mortality in low- and middle-income countries (LMICs).
