"The purpose of this [document] is to provide the reader with vital communication concepts and tools to assist in preparing for and responding to a severe influenza pandemic in the United States. The focus of the book is on the possibility of a severe pandemic. Although the concepts do apply to less intense public health challenges, they may not need to be executed at the same level of intensity. This book is intended to be used as an addition to the CDC Crisis and Emergency Risk Communication coursebook (Reynolds, Galdo, Sokler, 2002) and the Crisis and Emergency Risk Communication: By Leaders for Leaders coursebook (Reynolds, 2004). The concepts in this book do not replace, but, instead, build on the first two books. This book shares foundational concepts that will support your communication work and should be relevant even as the circumstances surrounding a severe pandemic may change. Nonetheless, the information in this book is current as of October 2007. As major events occur, especially related to countermeasures such as pandemic vaccine development, some assumptions may change."
