Based on diagnostic criteria by CDC most SUIDs are reported as one of three types of infant deaths: SIDS, unknown cause, and accidental suffocation and strangulation in bed. About half of SUIDs are SIDS. SIDS, a type of SUID is referred to or described by various names for many years, and currently defined as the sudden death of infants under the age of one-year-old that cannot be explained after performing a comprehensive investigation and a clinical history and autopsy examination
