Listeria infections occur most often in newborns and elderly patients. Neonatal infections can be subdivided into early onset and late-onset disease.

  • Early onset neonatal infections (< 5 d) begin at a mean age of 1.5 days.

  • Late-onset neonatal infections (>5 d) begin at a mean age of 14 days.

  • Postnatal infections usually occur in immunocompromised children and are less common than neonatal infections.
