Child health encompasses physical, mental and social well-being of children under the age of five. The leading causes of under-five deaths are pre-term birth complications, pneumonia, birth asphyxia, diarrhoea and malaria. Malnutrition contributes to nearly half of all under-five deaths. All these conditions contribute hugely to child impairments too. Common impairments and activity limitations related to child health including birth defects, cerebral palsy, developmental delays, burns, falls and injuries and road traffic injuries are outlined and different examples of rehabilitation across the care cycle are given. A case study of cerebral palsy in Haiti is cited.
