Neonatal death refers to the death of a baby within the first 28 days of life. This period is critical as newborns are particularly vulnerable to health complications. Common causes of neonatal death include premature birth, birth defects, infections, and complications during delivery. Preventive measures, such as proper prenatal care and skilled birth attendance, can significantly reduce the risk of neonatal death. Organizations like the World Health Organization work to improve maternal and infant health, aiming to lower neonatal mortality rates globally through education and healthcare initiatives.
