I chose this book as a textbook for an undergraduate summer course on global and public health. The book is probably among the best available and I found it providing the level of information needed for a short course. The chapters are short enough to each be read in a couple of hours or so making them good homework assignments. The book covers the main areas of global health. Some chapters would have benefited from expansive discussion such as the environmental health chapter that focused on water quality and sanitation or infectious diseases chapter. Topics of tobacco or chronic diseases are not covered or missed from the book. But in all, this is a good book and written in an easy and understandalbe language even for the lay person and I would recommend it.
