Dedication
This edition of the Red Book is dedicated to Ralph D. Feigin, MD, FAAP. Although Ralph never served on the AAP Committee on Infectious Diseases, there are very few chapters in this book that were not influenced by his considerable body of work or that of his trainees. In fact, a true listing of his accomplishments in pediatrics and pediatric infectious diseases would likely require a book this size. Ralph planned on being a general pediatrician, but entered the field of infectious diseases almost by accident. As a medical student, he learned how to measure amino acids in human blood, a relatively new science at the time. When he entered the military in 1965, he was assigned to the US Army Research Institute of Infectious Diseases at Fort Detrick, Maryland, where he performed ground-breaking work on the circadian periodicity of amino acid metabolism during infection. Thus, a great career was launched. A few of his subsequent contributions to the understanding of infectious diseases and their management in children include:
- Defining many of the metabolic changes that occur during the incubation period and early phases of clinical infectious diseases
- Using animal models to document that the time of day when a viral or bacterial infection occurs may have a marked effect on morbidity and mortality
- Providing one of the first descriptions of the effectiveness of clindamycin for methicillin-susceptible Staphylococcus aureus infections
- Defining the stability of antimicrobial agents in parenteral solutions, which still serves as the basis for most manufacturers' recommendations for intravenous use
- Contributing to epidemiologic studies showing that a single dose of measles vaccine would not be an effective strategy to eradicate measles and documenting the development of atypical measles syndrome in previously immunized children
- Defining the pharmacokinetics of cefazolin in children
- Reporting detailed epidemiologic studies of the occurrence of leptospirosis in urban populations and documenting transmission from healthy immunized dogs to humans
- Performing detailed sequential long-term (520 years) prospective evaluations of children with bacterial meningitis to determine how epidemiology and pathogenesis related to clinical manifestations and sequelae
- Delineating the role of the syndrome of inappropriate antidiuretic hormone secretion in children with bacterial meningitis
- Contributing to defining adherence of Haemophilus influenzae to epithelial cells as a necessary requirement for colonization and/or invasion
Impressive as these accomplishments are, they only scratch the surface of Ralph's contribution to pediatrics. He served as President of the Society for Pediatric Research, the American Pediatric Society, and the Association of Medical School Pediatric Department Chairs. He authored or coauthored 15 books, including 6 editions of the Textbook of Pediatric Infectious Diseases, and was coeditor of Oski's Pediatrics: Principles and Practice. He served as the Associate Editor of Pediatrics and Editor for the Pediatric Division of Up-To-Date, Inc. Beginning in 1974, he served as a consultant to the Surgeon General of the US Army on defense of the United States against biologic warfare. He was a vocal advocate for the need to consider the special needs of children in disaster planning, including events of biological terrorism. He also served as a member of the Board of Governors and the Finance Committee for the Clinical Center of the National Institutes of Health, again advocating for promotion and funding of pediatric research. Ralph's many accomplishments were recognized in 2007 with his receipt of the John Howland Award, the penultimate award in pediatrics.
Anyone who knew Ralph understands that his greatest professional passion was teaching. The fabled "Feigin rounds" were a truly unique experience in the art of differential diagnosis. He won the "Outstanding Teacher Award" from the medical students so often that he had to be retired from competition. When Ralph was asked how he built the pediatrics program at Baylor College of Medicine into the largest one in the United States, he emphatically stated that it started with the residency program. In his 31 years as a department chairman, Ralph helped train more than 1000 residents, and his department trained more than 900 fellows. His graduates are members of the faculty at 109 US medical schools and include 55 division heads and 5 department chairs or deans of medical schools. As recognition of his prowess, he received the Lifetime Educational Achievement Award from the American Academy of Pediatrics.
Although his professional accomplishments speak volumes, they reflect only one part of the man himself. Ralph was noted for his boundless energy and limitless optimism. He was one of the rare leaders who turned his personal vision of excellence into reality, but maintained his sense of proportion and humanity. He was kind, gentle, and compassionate in the best tradition of pediatricians. He was generous with his wisdom and his time, with his door always open to friends and colleagues, residents, and students. He also was devoted to his family. With his wife Judy (the "other Dr. Feigin"), he raised 2 daughters and a son and has 6 grandchildren, all of whom live in Houston.
It is difficult to think of anyone who has contributed more to pediatrics and the study of infectious diseases in the last 4 decades than Ralph Feigin. He was a brilliant clinician, accomplished researcher, creative administrator, unparalleled teacher, devoted family man, and revered mentor. He has forever changed the study of pediatric infectious diseases. This edition of the Red Book is dedicated to Ralph to thank him on behalf of all the children and pediatricians whose lives he has touched.

Preface
The Red Book is a unique source of information on immunizations and infectious diseases for practitioners. The practice of pediatric infectious diseases is changing rapidly. With the limited time available to the practitioner, the ability to quickly obtain up-to-date information about new vaccines and vaccine recommendations, emerging infectious diseases, new diagnostic modalities, and treatment recommendations is essential. The Committee on Infectious Diseases of the American Academy of Pediatrics (AAP) and the editors of the Red Book are dedicated to providing the most current and accurate information available in the concise, practical format for which the Red Book is known.
The value of the Red Book is further enhanced by the Red Book Online (www.aapredbook.org ), where statements and recommendations from the AAP and other important information that becomes available during the 3 years between editions of Red Book are provided. Another important resource is the visual library of Red Book Online, which has been updated and expanded to include more images of infectious diseases, examples of classic radiologic and other findings, and recent epidemiology of infectious diseases.
The Committee on Infectious Diseases relies on information and advice from many experts, as evidenced by the lengthy list of contributors to Red Book . We especially are indebted to the many contributors from other AAP committees, the Centers for Disease Control and Prevention, the Food and Drug Administration, the National Institutes of Health, the Canadian Paediatric Society, the World Health Organization, and many other organizations and individuals who have made this edition possible. In addition, suggestions made by individual AAP members to improve the presentation of information on specific issues and on topic selection have been incorporated into this edition.
Most important to the success of this edition is the dedication and work of the editors, whose commitment to excellence is unparalleled. Under the able leadership of Larry K. Pickering, MD, editor, with associate editors Carol J. Baker, MD, David W. Kimberlin, MD, and Sarah S. Long, MD, this new edition was made possible. We also are indebted to Edgar O. Ledbetter, MD, for his invaluable and untiring efforts to gather and organize the slide materials that make up the visual library of Red Book Online and are part of the electronic versions of the Red Book .
As noted in previous editions of the Red Book , some omissions and errors are inevitable in a book of this type. We ask that AAP members continue to assist the committee actively by suggesting specific ways to improve the quality of future editions.
Joseph A. Bocchini, Jr, MD, FAAP
Chairperson, Committee on Infectious Diseases

Introduction
The Committee on Infectious Diseases (COID) of the American Academy of Pediatrics (AAP) is responsible for developing and revising guidelines for the AAP for control of infectious diseases in children. At intervals of approximately 3 years, the committee issues the Red Book: Report of the Committee on Infectious Diseases , which contains a composite summary of current AAP recommendations concerning infectious diseases in and immunizations for infants, children, and adolescents. These recommendations represent a consensus of opinions developed by members of the committee in conjunction with liaison representatives from the Centers for Disease Control and Prevention (CDC), the Food and Drug Administration (FDA), the National Institutes of Health, the National Vaccine Program Of.ce, the Canadian Paediatric Society, the American Thoracic Society, Red Book consultants, and numerous collaborators. This edition is based on information available as of January 2009.
Unanswered scienti.c questions, the complexity of medical practice and technology, continuous new information, and inevitable differences of opinion among experts result in inherent limitations of the Red Book . In the context of these limitations, the committee endeavors to provide current, relevant, science-based recommendations for prevention and management of infectious diseases in infants, children, and adolescents. In some cases, other committees and experts may differ in their interpretation of data and resulting recommendations. In some instances, no single recommendation can be made because several options for management are equally acceptable.
In making recommendations in the Red Book , the committee acknowledges these differences in viewpoints by use of the phrases "most experts recommend..." and "some experts recommend..." Both phrases indicate valid recommendations, but the first signifies more support among experts, and the second, less support. Hence "some experts recommend..." indicates a minority view that is based on data and/or experience and is sufficiently valid to warrant consideration.
Inevitably in clinical practice, questions arise that cannot be answered on the basis of currently available data. In such cases, the committee attempt to provide guidelines and information that, in conjunction with clinical judgment, will facilitate well-reasoned decisions. We appreciate questions, different perspectives, and alternative recommendations that we have received, and encourage any suggestions or correspondence that will improve future editions of the Red Book . Through this process, the committee seeks to provide a practical and authoritative guide for physicians and other health care professionals in their care of infants, children, and adolescents.
To aid physicians and other health care professionals in assimilating current changes in recommendations in the Red Book , a list of major changes has been compiled (see Summary of Major Changes, p xxix). However, this listing only begins to cover changes that have occurred in each chapter and section. Health care professionals should consult individual chapters and sections of the book for current guidelines. In addition, new information inevitably begins to outdate some recommendations in the Red Book , and necessitates that health care professionals remain informed of new developments and resulting changes in recommendations. Between editions, the AAP publishes new recommendations from the committee in Pediatrics , in AAP News , and on the Red Book Online Web site (www.aapredbook.org ). In this edition, we continue to provide Web site addresses throughout the text to enable rapid access to new information. The Red Book Online Web site provides access to important Red Book errata that may have occurred. On Red Book Online, you can enroll for e-mail alerts to be noti.ed automatically when new errata have been announced.
When using antimicrobial agents, physicians should review the package inserts (product labels) prepared by manufacturers, particularly for information concerning contraindications and adverse events. No attempt has been made in the Red Book to provide this information, because it is available readily in the Physicians' Desk Reference , online (www.pdr.net ), and in package inserts (product labels). As in previous editions, recommended dosage schedules for antimicrobial agents are given (see Section 4, Antimicrobial Agents and Related Therapy). Recommendations in the Red Book for drug dosages may differ from those of the manufacturer in the package insert. Physicians also should be familiar with information in the package insert for vaccines and immune globulins as well as recommendations of other committees (see Sources of Vaccine Information).
This book could not have been prepared without the dedicated professional competence of many people. Edgar O. Ledbetter, MD, H. Cody Meissner, MD, and Jon R. Almquist, MD, served as Red Book reviewers appointed by the AAP Board of Directors. Dr Ledbetter also led the charge in gathering and organizing the new slide materials for the electronic part of the Red Book . The AAP staff has been outstanding in its committed work and contributions, particularly Alison Siwek and Hope Hurley, managers, who served as the administrative directors for the committee and coordinated preparation of the Red Book ; Jennifer Pane, senior medical copy editor, who improved every aspect of the Red Book ; Darlene Mattefs, department assistant; Barbara Drelicharz, division assistant;Peg Mulcahy, graphic designer; and Jeff Mahony, Mark Ruthman, and Mark Grimes, Department of Marketing, who make the Red Book Online and other Red Book products possible. Special appreciation is given to Stephanie Renna, assistant to the editor, for her work, patience, and support. Marc Fischer, MD, of the CDC, and R. Douglas Pratt, MD, and Lisa Lee, MD, of the FDA, devoted time and effort in providing input from their organizations. I am especially indebted to the associate editors Carol J. Baker, MD, Sarah S. Long, MD, and David W. Kimberlin, MD, for their expertise, tireless work, good humor, and immense contributions in their editorial and committee work. Georges Peter, MD, continues to provide constant support and advice and has left his imprint on all future editions of the Red Book . Members of the committee contributed countless hours and deserve appropriate recognition for their patience, dedication, revisions, and reviews. As a committee, we particularly appreciate the guidance and dedication of the current committee chairperson, Joseph A. Bocchini, MD, whose knowledge, dedication, insight, and leadership are re.ected in the quality and productivity of the committee's work. I thank Mimi for always being there and for her patience, understanding, and neverending support.
There are many other contributors whose professional work and commitment have been essential in the committee's preparation of the Red Book . Of special note is the person to whom this edition of the Red Book is dedicated, Ralph D. Feigin, MD, who was an exceptional leader, a constant inspiration, and a good friend. His death leaves a void in all of our lives.
