Preface

To stay on the cutting edge of travel health information, this latest edition of the CDC Yellow Book: Health Information for International Travel has been extensively revised. The book serves as a guide to the practice of travel medicine, as well as the authoritative source of US government recommendations for immunizations and prophylaxis for foreign travel. As international travel continues to become more common in the lives of US residents, having at least a basic understanding of the medical problems that travelers face has become a necessary aspect of practicing medicine. The goal of this book is to be a comprehensive resource for clinicians to find the answers to their travel health–related questions.
