The American Academy of Pediatrics (AAP) Red Book® Atlas of Pediatric Infectious Diseases,
3rd Edition, is a summary of key disease information from the AAP Red Book®: 2015 Report of
the Committee on Infectious Diseases. It is intended to be a study guide for students, residents,
The visual representations of common and atypical clinical manifestations of infectious diseases
provide diagnostic information not found in the print version of the Red Book. The juxtaposition
of these visuals with a summary of the clinical features, epidemiology, diagnostic methods, and
treatment information hopefully will serve as a training tool and a quick reference. The Red Book
Atlas is not intended to provide detailed treatment and management information but rather a
big-picture approach that can be reﬁned by consulting reference texts or infectious disease
specialists. Complete disease and treatment information from the AAP can be found at http://
redbook.solutions.aap.org, the electronic version of the Red Book.
This Red Book Atlas could not have been completed without the superb assistance of Peter Lynch,
Barrett Winston, Jason Crase, Theresa Wiener, and Peg Mulcahy at the AAP and of those physi-
cians who photographed disease manifestations in their patients and shared these with the AAP.
Some diseases are rarely seen today because of improved preventive strategies, especially immuni-
zation programs. While photographs can’t replace hands-on experience, they have helped me to
consider the likelihood of a correct diagnosis, and I hope this will be so for the reader. I also want
to thank those individuals at the Centers for Disease Control and Prevention who have generously
provided many photographs of the etiologic agents, vectors, and life cycles of parasites and proto-
zoa relevant to these largely domestic infections.
The study of pediatric infectious diseases has been a challenging and ever-changing professional
life that has brought me great joy. To gather information with my ears, eyes, and hands (the his-
tory and physical examination), to place this into the context of relevant epidemiology and incu-
bation period, and then to select a few appropriate diagnostic studies is still exciting for me.
Putting these many pieces together and arriving at the correct diagnosis is akin to solving a crime.
On many occasions, just seeing the clue (a characteristic rash, an asymmetry, a swelling) will solve
the medical puzzle, lead to recovery with the proper management, and bring the satisfaction
almost nothing can replace. It is my hope that the readers of the third edition of the Red Book
Atlas might ﬁnd a similar enthusiasm for the ﬁeld.
