HaSET is focused on understanding the causes of morbidity and mortality and using this knowledge to develop interventions to improve health. Evidence on the incidence and causes of morbidity and mortality among pregnant women and children are largely unknown in settings like Ethiopia. Priority-setting for policies, programs and research to prevent diseases requires current and accurate health data. Reliable estimates on childhood and pregnancy related morbidity and mortality are essential for development of appropriate health policies. Such data are also needed for the implementation of health interventions to prevent maternal and child deaths and morbidities that occur worldwide each year.
