In an era of unprecedented global wealth, millions of children across the world are facing a health crisis. A total of 150 million children still grown up malnourished, prevented from developing to their full mental and physical potential. Every year over 10 million children die from readily preventable causes. Although the international community has set challenging targets for reducing child mortality and childhood diseases, in many of the world's countries the situation is getting worse, not better. This report examines the global policy context behind the child health crisis. In particular, it looks at the General Agreement on Trade in Services (GATS) and the World Trade Organization's drive to increase international trade services such as water and health care. Save the Children's analysis suggests that this is the wrong model to follow if countries wish to develop strong public health systems for all their people. The report concludes that the market discipline included within GATS undermine national efforts to develop public health systems, and calls for the Agreement to be revised.
