Several factors contribute to childhood mortality, including:
1. [Infectious diseases]: Diseases such as pneumonia, diarrhea, and malaria remain leading causes of death among young children, especially in low-income countries. 2. [Malnutrition]: Malnutrition weakens the immune system, making children more vulnerable to infections and diseases. 3. [Neonatal conditions]: Complications during birth, prematurity, and congenital abnormalities are significant causes of death in the first month of life. 4. [Lack of access to healthcare]: Inadequate healthcare services, including immunizations, can lead to preventable deaths. 5. [Environmental factors]: Poor sanitation, unsafe drinking water, and exposure to pollutants can increase the risk of fatal diseases.
