Background: Brief Resolved Unexplained Event (BRUE) or sudden infant death syndrome (SIDS) is the sudden and unexpected death of an infant less than 12 months old. The research aimed to understand the background of the disease called BRUE and try to understand the reason behind the untimely death of infants. Methods: The design that would be ideal for executing the considered research work is descriptive design. This is because the cross-sectional approach of methodology was used and for this reason, it needs a detailed assessment of the research perspective which would be facilitated by the chosen design. There are two approaches that are mostly used while proceeding with the research work and they are inductive as well as deductive approaches. In this case, an approach that is inductive in nature was utilized because this approach helped in developing new theories and understanding the perspective of the people regarding the disease called BRUE. Results: Study included 515 participants. Participants reported that the most frequent physical factor leading to BRUE is defects in brain (n= 264, 51.3%). Some participants reported that they considered taking medications at infantile stage might lead to BRUE (n= 191, 37.1%). Furthermore, about half of participants reported that BRUE is not a common incident (n= 242, 47%). More than half of study partisans cannot understand BRUE (n= 294, 57.1%). In addition, half of study participants believed that maternal factors could lead to BRUE (n= 266, 51.7%). Participants reported that age is the highest prone risk to BRUE (n= 310, 60.2%). They reported closely for both no overheating of baby’s body (n= 249, 48.3%) and proper sleeping posture (n= 237, 46%) Conclusion: This research aimed to learn more about BRUE and the causes of premature neonatal mortality. Some worried that giving their babies drugs may raise their risk of BRUE. Over half claimed BRUE is uncommon. Over half of research supporters disagree with the BRUE definition. 50% of participants felt maternal factors caused BRUE. Half of those surveyed didn't know whether BRUE is preventable. Two-thirds of the study participants felt sleeping awkwardly may raise BRUE risk.
