What are the greatest challenges facing health systems now? How are these challenges identified and measured? In the case of an epidemic, disaster, or armed conflict, how do experts determine what health care interventions to use? Is it possible to eradicate diseases like Guinea worm, tuberculosis and HIV? How can we address mental health disorders, cancers, and non-communicable diseases and who is best equipped to do so?
