The Integrated Management of Neonatal and Childhood Illness (IMNCI) was developed by WHO and UNICEF to reduce morbidity and mortality among children under five years old. It takes a curative, preventive, and promotive approach through improving family practices, ensuring access to essential medicines, strengthening health care workers' skills, and engaging communities. The IMNCI process involves assessing and classifying a child's illness, identifying and providing appropriate treatment, counseling the mother, and arranging follow-up care. Its overall goal is to improve growth, development, and survival of young children.
