Sudden unexpected infant death (SUID) is a major contributor to infant death and a persistent public health issue. After an initial decline after the 1994 “Back to Sleep” campaign, SUID numbers plateaued. Currently, ∼10 infants die suddenly and unexpectedly each day in the United States. In 2019, we established a surveillance system for SUID in Cook County, Illinois, partnering our academic medical center, the Cook County Medical Examiner’s Office, and child death review to create the Cook County SUID Case Registry. Our data show that, in Cook County, including the city of Chicago, ∼1 infant dies unexpectedly during sleep every week. Of these SUID, ∼25% were because of suffocation/possible suffocation. SUID peaks at 30 to 60 days old. SUID rates are 15 times higher in non-Hispanic Black infants and 3 times higher in Hispanic infants, compared with white infants. Nearly all involved 1 or more unsafe sleep factors. SUID are concentrated in community areas experiencing high hardship. Through our Community Partnership Approaches for Safe Sleep–Chicago team, we have developed collaborative prevention approaches in affected communities, allowing for conversations with families and those who support them to better understand barriers to safe sleep that they experience. These partnerships and our data allow for tailoring of informed prevention approaches to address upstream factors driving disproportionate infant mortality in historically disinvested communities, as well as optimizing the immediate risks posed by the infant sleep environment. Data from our system show the number of SUID declining modestly since our prevention work began.
