Book excerpt: The new edition of this unique resource, grounded on an understanding that our global world is more connected than it has ever been, provides an essential survey of infectious diseases based on both clinical presentation and geographical area of exposure. This book is split into three main sections. The first section offers an overview of the geopolitics of infectious diseases, highlighting the channels through which a disease can spread from one region or country to another, including air travel, shipping or migration. The second section provides a comprehensive overview of each region, highlighting the infectious diseases common to that part of the world. The final section includes a chapter examining new infections of concern, and a chapter discussing infectious diseases in the context of global climate change. Thoroughly updated with the latest clinical data and featuring contributions from leading scholars and clinicians in the field, this book is a timely and important resource for practitioners and scholars across Clinical Medicine, Epidemiology and Public Health.
