The signs of neonatal sepsis are usually characterized by the infant generally "not doing well." Poor temperature control, usually with hypothermia, lethargy, poor feeding, pallor, cyanosis or mottling, and jaundice, may be evident. Seizures are not a manifestation of sepsis. Severe neurologic sequelae may occur in low–birth-weight infants with sepsis. Hyperthermia is rare in neonatal sepsis. Urinary output is not affected by sepsis.
