           Partnerships have been foundational to the American Academy of Pediatrics (AAP) since
           its establishment in 1930. At the individual level, pediatricians have partnered with one
           another to improve the lives of the children for whom they care. At the organizational
           level, the AAP has partnered with groups that impact children’s health, such as the
           Centers for Disease Control and Prevention (CDC), the American College of Obstetri-
           cians and Gynecologists (ACOG), the American Academy of Family Physicians (AAFP),
           and the US Food and Drug Administration (FDA). And at the governance level, the
           Academy has partnered with local and national leaders across party lines to advance
           policies that benefit children. At their core, partnerships have been the fundamental
           reason for the Academy’s success in advancing the health and well-being of children for
           almost 90 years.
                The 2018 Red Book: Report of the Committee on Infectious Diseases is dedicated to two of
           the Academy’s most influential partners, Larry K. Pickering, MD, and Carol J. Baker,
           MD. Drs. Pickering and Baker personify the highest ideals of effective collaboration
           and partnership. Both are passionate advocates for children who have harnessed their
           energies and friendship to achieve more together than would have been accomplished
           separately. As Editor and Associate Editor, respectively, for 5 editions of the Red Book
           spanning 15 years, Drs. Pickering and Baker worked side by side to create a product that
           is used the world over by pediatricians caring for children. To be sure, the editions of the
           Red Book that they led in 2000, 2003, 2006, 2009, and 2012 were very much a group
           effort, with several skilled associate editors and scores of Committee on Infectious
           Diseases (COID) members and liaisons also guiding the development of great Red Books.
           But it was Larry and Carol who inspired and led this group to achieve truly remarkable
           things.
                 Carol Baker entered medicine in an era when women physicians were rare. She was
           the only woman in her medical school class at Baylor College of Medicine from 1964 to
           1968. Following graduation, she completed an internship in pediatrics at the University of
           Southern California before returning to Baylor for residency and pediatric infectious
           disease fellowship training. She then spent two years at Harvard Medical School as a
           research fellow and instructor before accepting a faculty position at Baylor College of
           Medicine in 1975, where she has remained for her entire career. Carol is responsible for
           generating an extraordinary amount of information regarding Streptococcus agalactiae. She
           performed the seminal epidemiologic and natural history investigations of the role this
           pathogen plays in neonatal sepsis and meningitis, correlated maternal colonization of
           group B streptococcus at delivery with risk to the neonate, and devised the screening plan,
           in collaboration with the AAP, CDC, and ACOG, that is used worldwide for the
           prevention of early-onset group B streptococcal disease, whereby women are universally
           screened for colonization with the bacteria near the end of pregnancy and treated
           perinatally if positive.
                 Larry Pickering completed medical school at West Virginia University School of
           Medicine in 1970 and then completed his residency and pediatric infectious diseases
           fellowship training at Washington University in St. Louis. He was recruited to the
           University of Texas School of Medicine at Houston in 1974, where he began a long
           career focusing on viral, bacterial, and protozoal enteric diseases. His research explored
           the protective factors against enteric pathogens that are present in human milk, contrib-
           uting to the resurgence of breastfeeding across the country in the 1980s and 1990s.
           Larry’s work on the pathophysiology of enteric diseases was truly bench to bedside to
           bench and laid the groundwork for outbreak investigations, diagnostic advances, thera-
           peutic interventions, and prevention of enteric diseases through hygienic improvements
           and vaccine development.
                 Although at separate institutions, the environment in Houston was inclusive and col-
           laborative as well as a bit competitive. Drs. Baker and Pickering would see each other at
           least weekly at the citywide infectious disease conference, where representatives of the
           participating institutions would prepare and present cases for the meeting. At many, if not
           most, of these weekly meetings, Larry would present a patient for the stated purpose of
           stumping Carol, or vice versa. They forged a deep friendship based on profound respect
           for the clinical acumen, scientific rigor, and ethical underpinnings of the other. Their first
           publication together was in 1981, the case of a child with group A streptococcal meningi-
           tis. It was the first of many collaborative efforts.
                 After leaving UT Houston in 1992, Larry moved to Eastern Virginia Medical School,
           where he was vice chair for pediatric research. In 2001, he moved to the CDC to serve as
           the Senior Advisor to the Director and the Executive Secretary of the Advisory Commit-
           tee on Immunization Practices (ACIP). Larry served on the AAP COID from 1990–1996
           and was an Associate Editor of the 1994 and 1997 editions of the Red Book. Following
           publication of the 1997 Red Book, Larry was named Editor of the 2000 edition, and he
           immediately recruited Carol to serve as an Associate Editor. Carol served as a COID
           member from 1999–2005, and together she and Larry produced five editions of the Red
           Book. Their partnership extended to the CDC as well when Dr. Baker joined the ACIP
           in 2006 as a member and ascended to Chair of the ACIP from 2009–2012. Whether
           sitting side by side at ACIP meetings or around the conference room table at COID
           meetings, Drs. Pickering and Baker modeled respect for one another as they worked
           tirelessly toward the better health of all children. Their thoughtful and informed leader-
           ship at the AAP and CDC helped establish the current era of historically low rates of
           most vaccine-preventable diseases.
                There is an old African proverb that if you want to go fast, go alone; but if you want
           to go far, go together. Larry and Carol have always gone together, and children across
           the world have benefited from how far they traveled. This edition of the Red Book is
           dedicated to Larry and Carol as a small token of thanks and appreciation on behalf of all
           of the children and pediatricians whose lives are better because of their partnership.
                                                              Preface
           The Red Book, now in its 31st edition, has been a unique and valuable source of infor-
           mation on infectious diseases and immunizations for pediatric practitioners since 1938.
           In the 21st century, with the practice of pediatric infectious diseases changing rapidly and
           the limited time available to the practitioner, the Red Book remains an essential resource to
           quickly obtain current, accurate, and easily accessible information about vaccines and
           vaccine recommendations, emerging infectious diseases, diagnostic modalities, and
           treatment recommendations. The Committee on Infectious Diseases of the American
           Academy of Pediatrics (AAP), the editors of the Red Book, and the 500 Red Book contribu-
           tors are dedicated to providing the most current and accurate information available in
           the concise, practical format for which the Red Book is known.
                For the first time since the 2006 edition, the print version of the Red Book will be
           provided to every AAP member as part of their member benefit. This change reflects
           the Academy’s strong interest in its members’ needs. In a series of AAP Periodic Surveys
           conducted of its members, pediatricians expressed that the ease of retrieval of information
           from the book format is highly valued in the midst of busy practices.
                As with each of the last 4 editions, AAP members also will continue to have access to
           Red Book content on Red Book Online (www.aapredbook.org). AAP policy statements,
           clinical reports, and technical reports and recommendations endorsed by the AAP are
           posted on Red Book Online as they become available during the 3 years between Red Book
           editions, and online chapters are modified as needed to reflect these changes. Red Book
           users also are encouraged to sign up for e-mail alerts on www.aapredbook.org to
           receive new information and policy updates between editions.
                Another important resource is the visual library of Red Book Online, which is continu-
           ally updated and expanded to include more images of infectious diseases, examples of
           classic radiologic and other findings, and recent information on epidemiology of infec-
           tious 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, sections, and councils;
           the American Academy of Family Physicians; the American College of Obstetricians and
           Gynecologists; the American Thoracic Society; the Canadian Paediatric Society; the
           Centers for Disease Control and Prevention; the US Food and Drug Administration; the
           National Institutes of Health; the National Vaccine Program Office; the Pediatric
           Infectious Diseases Society; la Sociedad Latinoamericana de Infectología Pediátrica; 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 whenever possible.
                Most important to the success of this edition is the dedication and work of the editors,
           whose commitment to excellence is unparalleled. This new edition was made possible
           under the able leadership of David W. Kimberlin, MD, editor, along with associate
           editors Michael T. Brady, MD, Mary Anne Jackson, MD, and Sarah S. Long, MD. We
           also are indebted to H. Cody Meissner, MD, for his untiring efforts to gather and organ-
           ize the slide materials that make up the visual library of Red Book Online and are part of
           the electronic versions of the Red Book, and to Henry H. Bernstein, DO, MHCM, for his
           continuous efforts to maintain up-to-date content as editor of Red Book Online.
                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 ac-
           tively by suggesting specific ways to improve the quality of future editions. The committee
           membership and editorial staff hope that the 2018 Red Book will enhance your practice
           and benefit the children you serve.
                                                       Introduction
           The Committee on Infectious Diseases (COID) of the American Academy of Pediatrics
           (AAP) is responsible for developing and revising guidance from the AAP for management
           and control of infectious diseases in infants, children, and adolescents. Every 3 years, the
           COID issues the Red Book: Report of the Committee on Infectious Diseases, which contains a
           composite summary of current recommendations representing the policy of the AAP on
           various aspects of infectious diseases, including updated vaccine recommendations for the
           most recent US Food and Drug Administration (FDA)-licensed vaccines for infants, chil-
           dren, and adolescents. These recommendations represent a consensus of opinions based
           on consideration of the best available evidence by members of the COID, in conjunction
           with liaison representatives from the Centers for Disease Control and Prevention (CDC),
           the FDA, the National Institutes of Health, the National Vaccine Program Office, the
           Canadian Paediatric Society, the American Thoracic Society, the Pediatric Infectious
           Diseases Society, the American Academy of Family Physicians, the American College of
           Obstetricians and Gynecologists, Red Book consultants, and scores of collaborators. This
           edition of the Red Book is based on information available as of February 2018. The Red
           Book is your own personal infectious disease consultant, on your bookshelf and ready for
           you 24 hours a day, 7 days a week. Arguably, it is most valuable in those circumstances in
           which definitive data from randomized controlled trials are lacking. It is in those situa-
           tions that guidance from experts in the field is most critical, and the COID has literally
           hundreds of years of cumulative expertise to bring to bear on such recommendations.
           The Red Book is formatted as hard copy, mobile app, and online Web version, with the
           electronic versions containing links to supplemental information, including visual images,
           graphs, maps, and tables.
                Preparation of the Red Book is a team effort in the truest sense of the term. Within
           weeks following the publication of each Red Book edition, all Red Book chapters are sent for
           updates to primary reviewers who are leading national and international experts in their
           specific areas. For the 2018 Red Book, one quarter of primary reviewers were new to this
           process, ensuring that the most up-to-date information has been included in this new edi-
           tion. Following review by the primary reviewer, each chapter is returned to the assigned
           Associate Editor for incorporation of the reviewer’s edits. The chapter then is disseminated
           to content experts at the CDC and FDA and to members of all AAP Sections, Commit-
           tees, and Councils that agree to review specific chapters for their additional edits as
           needed, after which it again is returned to the assigned Associate Editor for harmonization
           and incorporation of edits as appropriate. Two designated COID reviewers then complete
           a final review of the chapter, and it is returned to the assigned Associate Editor for inclu-
           sion of any needed additional modifications. Finally, each chapter is discussed and debated
           by the full COID at its “Marathon Meeting,” held at the AAP during the spring of the
           year prior to publication, where it is finalized. Copyediting by the Editor and senior medi-
           cal copy editor follows, and the book then is reviewed by the Red Book reviewers appointed
           by the AAP Board of Directors. In all, 1000 hands have touched the 2018 Red Book prior to
           its publication! That so many contributors dedicate so much time and expertise to this
           product is a testament to the role the Red Book plays in the care of children.
                Through this deliberative and inclusive process, the COID endeavors to provide
           current, relevant, evidence-based recommendations for the prevention and management
           of infectious diseases in infants, children, and adolescents. Seemingly unanswerable
           scientific questions, the complexity of medical practice, ongoing innovative technology,
           continuous new information, and inevitable differences of opinion among experts all are
           addressed during production of the Red Book. In some cases, other committees and experts
           may differ in their interpretation of data and resulting recommendations, and occasion-
           ally no single recommendation can be made because several options for management are
           equally acceptable. In such circumstances, the language incorporated in the chapter
           acknowledges these differing acceptable management options by use of the phrases “most
           experts recommend...” and “some experts recommend...” Both phrases indicate valid rec-
           ommendations, but the first phrase signifies more agreement and support among the ex-
           perts. Inevitably in clinical practice, questions arise that cannot be answered easily on the
           basis of currently available data. When this happens, the COID still provides guidance
           and information that, coupled with clinical judgment, will facilitate well-reasoned, clini-
           cally relevant decisions. Through this process of lifelong learning, the committee seeks to
           provide a practical 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 between the 2015 and 2018
           editions has been compiled (see Summary of Major Changes, p XXXV). However, this
           list only begins to cover the many in-depth changes that have occurred in each chapter
           and section. Throughout the Red Book, Internet addresses enable rapid access to new
           information. In addition, new information between editions from the COID, in the form
           of Policy Statements, Clinical Reports, and Technical Reports, are posted on Red Book
           Online (www.aapredbook.org), and online chapters are modified as needed with
           clear indications of where changes have been made. These completed work products are
           a result of the continuous reassessment by the COID of its current positions across the
           spectrum of pediatric infectious diseases, and demonstrate the dynamic process by which
           the Committee’s deliberations always are inclusive of new data and perspectives.
                Information on use of antimicrobial agents is included in the package inserts (product
           labels) prepared by manufacturers, including contraindications and adverse events. The
           Red Book does not attempt to provide this information comprehensively, because it is avail-
           able readily in the Physicians’ Desk Reference (www.pdr.net) and in package inserts.
           As in previous editions of the Red Book, recommended dosage schedules for antimicrobial
           agents are provided (see Section 4, Antimicrobial Agents and Related Therapy) and may
           differ from those of the manufacturer as provided in the package insert. Antimicrobial
           agents recommended for specific infections in the Red Book may or may not have an FDA
           indication for treatment of that infection. Physicians also can reference additional infor-
           mation in the package inserts of vaccines licensed by the FDA (which also may differ from
           COID and ACIP/CDC recommendations for use) and of immune globulins, as well as
           recommendations of other committees (see Sources of Vaccine Information, p 0), many of
           which are included in the Red Book.
                Likewise, we strive to utilize the accurate terminology for licensure, approval, or
           clearance of drugs and devices by the FDA. The correct term used depends on the
           classification of the product (eg, drug, biological product, or device) and, for devices,
           whether a “premarket notification” or a “premarket application” has been submitted.
           Drugs are approved by the FDA. Biologic products (eg, vaccines, immunoglobulin
           preparations) are licensed by the FDA, and vaccines are approved for use in certain
           populations and age groups. The FDA “clears” devices after reviewing premarket
           notifications, but “approves” devices after reviewing a premarket application. Whether a
           premarket notification or premarket application needs to be filed depends on the
           classification of the medical device. “Cleared” devices (also called “510 (k)” or “premarket
           notification” devices) can be searched at www.fda.gov/MedicalDevices/
           ProductsandMedicalProcedures/DeviceApprovalsandClearances/
           510kClearances/ucm089319.htm. Devices@FDA (www.accessdata.fda.gov/
           scripts/cdrh/devicesatfda/index.cfm) is more comprehensive and includes both
           “cleared” and “approved” tests and other devices. Where we fail in the Red Book to select
           the appropriate term for a given product, we apologize for any (additional) confusion this
           adds to this regulatory structure.
                This book could not have been prepared without the dedicated professional compe-
           tence of many people. The AAP staff has been outstanding in its committed work and
           contributions, particularly Jennifer Frantz, senior manager, who served as the administra-
           tive director for the COID and coordinated preparation of the Red Book; Jennifer Shaw,
           senior medical copy editor; Linda Rutt, division coordinator; Theresa Wiener, manager
           of publishing and production services; and all of the directors and staff of the AAP pub-
           lishing and marketing groups who make the full Red Book product line possible.
                Marc Fischer, MD, of the CDC, and Karen M. Farizo, MD, of the FDA, devoted
           time and effort in providing significant input from their organizations. Meg Fisher, MD,
           and Renée Jenkins, MD, served as Red Book reviewers appointed by the AAP Board of Di-
           rectors, spending scores of hours reviewing the final chapters for consistency and accu-
           racy. I am especially indebted to the Associate Editors Michael T. Brady, MD, Mary
           Anne Jackson, MD, and Sarah S. Long, MD, for their expertise, tireless work, good
           humor, and immense contributions in their editorial and committee work. Members
           of the COID contributed countless hours and deserve appropriate recognition for their
           patience, dedication, revisions, and reviews. The COID appreciates the guidance and
           dedication of Carrie L. Byington, MD, COID Chairperson, whose knowledge, dedica-
           tion, insight, and leadership are reflected in the quality and productivity of the commit-
           tee’s work. I thank my wife, Kim, for always being there and for her patience, under-
           standing, and never-ending support as this edition of the Red Book came to fruition.
                I also would like to personally thank Karen Remley, MD, for her leadership of the
           AAP and for her support of the COID and the Red Book. In her travels across the country,
           Dr. Remley has heard first-hand the value that the Red Book brings to the treatment of
           children. These experiences mirror her own as a pediatric emergency medicine physician
           earlier in her luminous career. Dr. Remley has provided keen insights into the design of
           the new Red Book cover to be inclusive of the years that it will be current, between now
           and 2021. She also has tirelessly supported efforts across the AAP to be responsive to
           members’ stated desire to have access to the printed version of the Red Book, culminating
           in the AAP Board of Directors’ approval of providing a hard copy of the book to all AAP
           members as part of their member benefit. Her tireless fight for the welfare of all children
           is inspiring to all who look to the AAP for leadership.
                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 are the indi-
           viduals to whom this edition of the Red Book is dedicated, Larry K. Pickering, MD, and
           Carol J. Baker, MD. I have learned so much from each of them, and the legacies that
           they leave in pediatrics and the Red Book will endure for generations to come.
                                                                                          David W. Kimberlin, MD, FAAP

                years of age who are traveling to areas where cholera is a risk.
           118. Disease manifestations and risk factors for Other Vibrio Infections have been
                added to the chapter. Monotherapy for severe diarrhea using doxycycline or
                ciprofloxacin has been added as well.
           119. Description of West Nile Virus transmission via human milk has been expanded.
                The number of cases has been updated, along with infection incidence rates in more
                heavily affected states. A Web link to a review summarizing potential treatments
                (including Immune Globulin Intravenous with or without a high titer of WNV
                antibody, WNV recombinant humanized monoclonal antibody, interferon,
                corticosteroid, ribavirin) has been added.

                in the Yersinia enterocolitica and Yersinia pseudotuberculosis Infections
                chapter. The etiology of infection has been expanded to discuss differences in
                virulence gene distribution among Yersinia species, and correlating with clinical
                manifestations.
           121. Zika is a new chapter in the 2018 Red Book. Its development has been carefully
                coordinated to include input from Zika experts and to harmonize with diagnostic
                recommendations from the CDC, including partnership between the AAP and
                CDC on the evaluation and management of infants with possible congenital Zika
                    virus infection as the case incidence decreased in 2017. This chapter was early re-
                    leased online by the AAP in 2017 to aid in management.
