Paediatrics is the branch of medicine dealing with the development, care, and diseases of infants, children, and adolescents. It emerged over a century ago in response to an increasing awareness that children's health problems differ from adults and that a child's response to illness varies with age. The top five causes of mortality in Zambia are pneumonia, diarrhea, malaria, malnutrition, and HIV-related diseases. Pediatrics monitors indicators like under-five mortality rate and considers factors like a child's best interest, parental responsibility, and a child's developing autonomy and capacity for self-determination.
