Perinatal health refers to the health of a mother and her baby during the perinatal period, which typically spans from the 20th week of pregnancy to the first 28 days after birth. This stage is crucial for both maternal and infant well-being, as it involves monitoring and managing health conditions that can affect pregnancy and delivery. Key aspects of perinatal health include prenatal care, which helps ensure a healthy pregnancy, and postnatal care, which supports recovery and infant development. Factors such as nutrition, mental health, and access to healthcare services play significant roles in promoting positive outcomes for both the mother and the newborn.
