What is Sudden Unexpected Infant Death (SUID)?

Sudden Unexpected Infant Death (SUID) happens in infants less than one (1) year of age and the cause of death is not known until there is a complete investigation.

  • Each year in the United States, more than 4,500 infants die suddenly of no immediately obvious cause.
  • Half of these Sudden Unexpected Infant Deaths (SUID) are due to Sudden Infant Death Syndrome (SIDS).


What is Sudden Infant Death Syndrome (SIDS)?

Sudden Infant Death Syndrome (SIDS) is defined as the sudden death of an infant less than one (1) year of age that cannot be explained after a thorough investigation is conducted, including a complete autopsy, examination of the death scene, and review of the clinical history.

  • SIDS is the leading cause of death among infants aged one (1) month to one (1) year of age.
  • The overall rate of SIDS in the United States has declined by more than 50% since 1990.
