Introduction to Global Health is a comprehensive look at today’s most critical global health concerns and the actions that people around the world are taking to solve public health problems and to promote health and wellbeing. The Fourth Edition of Introduction to Global Health maintains the clarity and ease of use of the prior edition, while featuring a greater emphasis on the specific interventions that are being implemented to promote longer, healthier lives worldwide and prevent disease, disability, and early death in countries of all income levels. Every chapter balances material about pandemics, climate change, and other emerging threats to global public health with evidence of how global health interventions are enabling progress toward achieving health equity.
