Step-by-step explanation:
The most frequent cause of death in children under five years old in low-income countries are pneumonia, diarrhea, congenital anomalies, preterm birth complications, birth asphyxia/trauma, and malaria. These causes can be prevented or treated with affordable interventions including immunization, adequate nutrition, safe water and food, and quality care by a trained health provider.
The availability of doctors and nurses in low-income countries is significantly lower compared to nations with a high income. This lack of healthcare professionals contributes to the high rates of child mortality.
