The document provides an overview of Integrated Management of Childhood Illness (IMCI), which is an integrated approach to child health developed by WHO and UNICEF. IMCI focuses on well-being of children under five years old and includes preventive and curative elements implemented by families, communities, and health facilities. The integrated case management process for sick children ages 1 week to 5 years involves assessing and classifying the child's illnesses, identifying specific treatments, providing treatment instructions, counseling the mother, and follow-up care. The goal is to reduce mortality from major childhood illnesses like pneumonia, diarrhea, and malnutrition through improved skills and systems for managing sick children at primary health facilities.
