Fever is one of the most common complaints in pediatric practice and often a source of concern for both parents and clinicians. This practical, case-based guide walks pediatric trainees and practitioners through a systematic approach to diagnosing the cause of fever.

A distinctive feature is guidance on parental counseling in challenging situations. Key Features: Case-based, system-wise approach to diagnosing pediatric fever.
