Newborn infant

Alternative names


An infant is considered to be a “newborn” up to age one month. This is also called the neonatal period. It is important because it represents a short period of life where changes are very rapid and when many critical events can occur. During the first 30 days, most congenital defects (such as congenital heart disease) are discovered. Genetic abnormalities may manifest themselves and it is a time when infections such as congenital herpes, group B strep, Toxoplasmosis and others are discovered as they begin to have clinical effects.
