Sudden Unexpected Infant Death (SUID) and Sudden Death in the Young (SDY)

The Centers for Disease Control and Prevention’s (CDC)’s Division of Reproductive Health supports the Sudden Unexpected Infant Death (SUID) and Sudden Death in the Young (SDY) Case Registry to improve data quality on SUID and SDY case surveillance. Additionally, CDC collaborates with organizations and subject matter experts to support standardizing death investigations, including scene recreations with doll reenactments.

SUID and SDY Surveillance

The SUID and SDY Case Registry supports SUID monitoring programs in 22 states and jurisdictions. The registry builds on the child death review program. CDC collaborates with many other organizations to create guidelines and training materials for the investigation of infant deaths.

SUIDI Reporting Form

The Sudden Unexpected Infant Death Investigation Reporting Form is a voluntary tool and template for states and jurisdictions to use. The tool standardizes data collection to help improve classification of sleep-related infant deaths.

The Data Coordinating Center for SDY

The SDY Data Coordinating Center Case Registry gathers information about young people who die suddenly and unexpectedly. Babies, children, and young adults up to age 20 are included in the SDY Case Registry.
