SUID (Sudden Unexpected Infant Death also known as sudden unexplained infant death): is defined as
the sudden and unexpected death of an infant in which the manner and cause of death are not immediately obvious
prior to investigation.

SIDS (Sudden Infant Death Syndrome): Is defined as the sudden death of an infant under one year of age which
remains unexplained after a thorough case investigation, including performance of a complete autopsy, examination
of the death scene and review of the clinical history. SIDS is a diagnosis of exclusion, assigned only once all known
and possible causes of death have been ruled out.

How are SUID and SIDS different? SUID can be caused by metabolic disorders, hypothermia or hyperthermia,
neglect or homicide, poisoning, or accidental suffocation. Some SUIDs are ruled SIDS, others are sleep-related
deaths but ruled undetermined.
