In keeping with the previous edition - which was independently rated as the best global health book for undergraduates - Global Health 101, Fourth Edition is a clear, concise, and user-friendly introduction to the most critical issues in global health, illustrating key themes with an extensive set of case studies, examples, and the latest evidence. Drawing from his 40 years of experience working in international development and global health, as well as extensively teaching at both Yale and George Washington University, Richard Skolnik has substantially revised his bestselling textbook. This edition offers a significant amount of new and updated information, while maintaining the clarity, simplicity, and ease of use that has made this text so popular. Global Health 101, Fourth Edition builds in unique ways on evidence from a number of fundamental sources, including the Global Burden of Disease Studies, Disease Control Priorities, Third Edition, (DCP3), and Millions Saved.
