Test your knowledge of infectious diseases with Diagnosis Detective

March 1, 2024

Clinicians are invited to solve an infectious disease case every month with a Red Book Online feature called Diagnosis Detective.

Pediatric experts from AAP committees, councils and sections submit short, real-world cases, some of which include images. Multiple-choice questions ask about the diagnosis and treatment. Answers, explanations and links to additional information are provided.

The team of volunteers that submits cases is led by Kristina K. Bryant, M.D., FAAP, Red Book Online lead and member of the AAP Committee on Infectious Diseases (COID).

A group of COID members developed the feature for health care professionals, who use the content in both learning and teaching.
