Neonatus is a Latin term that refers to a newborn or a newly born individual. Derived from the Latin words "neo," meaning new, and "natus," meaning born, neonatus is typically used in the medical field to describe an infant during the immediate period after birth.
In the context of healthcare, neonatus refers to a newborn baby in the first 28 days of life, also known as the neonatal period. This term highlights the vulnerability and specific needs of a newborn, as they require specialized care and attention during this crucial stage of development. Neonatal healthcare focuses on monitoring and providing medical support to ensure the well-being and survival of neonatus.
The neonatal period is a critical time when the newborn undergoes various physiological changes and adaptation processes as they transition from intrauterine to extrauterine life. During this period, various assessments, screenings, and interventions are performed to ensure the optimal health and development of the neonatus.
Neonatus may also be used in broader contexts to simply refer to a newly born individual, regardless of their age as it pertains to the neonatal period. However, in the medical field, the term typically pertains to the specific age range of a newborn baby in the first few weeks of life.
