Abstract

Infectious diarrhea remains a significant global health challenge, causing considerable morbidity and, in severe cases, mortality, particularly among vulnerable populations such as young children and the elderly. This clinical guide, developed by the Infectious Diseases Society of America (IDSA), aims to provide evidence-based recommendations for the diagnosis and management of infectious diarrhea. It covers the identification of key pathogens, diagnostic testing strategies, and treatment protocols, with a focus on antibiotic stewardship and tailored therapeutic interventions. These guidelines emphasize the importance of accurate diagnosis to reduce unnecessary treatments, prevent antimicrobial resistance, and improve patient outcomes. By providing a structured approach to the clinical management of infectious diarrhea, this guide seeks to support healthcare professionals in delivering effective and consistent care.
