Death of a live- born infant within the first 28 days of life.
The passing away of an infant born alive within the initial four weeks of life is termed neonatal death. This type of death is categorized as either early or late: early neonatal deaths transpire during the first week of life, while late neonatal deaths occur from the conclusion of the first week until 27 days after birth. Roughly fifty percent of neonatal deaths in the UK stem from prematurity, approximately a quarter result from congenital malformations, and the remaining cases are attributed to various factors, including infections and challenges during delivery.
