Early-onset sepsis develops in the first 2-3 days after birth. Late-onset sepsis develops within 3-7 days after birth.

Neonatal sepsis is caused by bacteria. The infant may come in contact with bacteria during pregnancy, birth, or from the environment after birth.

Early-onset sepsis is caused by an infection from the mother. It may pass to the infant from the placenta or birth canal during birth. Antibiotics may be given to high risk mothers during labor. This may prevent early-onset bacterial sepsis in some infants.

Late-onset sepsis is caused by bacteria from the healthcare environment.
