In terms of under-five health, there are five leading disease--malaria, infectious diseases like pneumonia, and those kinds of things. We know what they are and we also know how to address them. The best way to address them is to do them in an integrated fashion so that all children get access to the bundle of interventions that are needed. They're very cost effective and they can be bundled together. You need a primary care worker to be able to deliver them to the children.

Those are some of the main factors. Across a continuum of care it's well known internationally what the main areas of intervention are. There's a broad set of areas there. We do know what the diseases are that kill children. We do know what the main causes of maternal mortality are.
