Challenges of Recognizing Serious Infections

Identifying serious bacterial infections in young children poses significant clinical challenges, particularly among febrile infants. With an increase in awareness about the potential severity of fevers, parents are now bringing their infants to emergency departments sooner after the onset of symptoms. This shift necessitates the need for effective clinical decision rules and biomarkers to assess the risk of invasive bacterial infections in these young patients. Current guidelines emphasize the importance of evaluating febrile infants with algorithms that consider the duration of fever, but there is variability in the performance of these rules based on how quickly the infant presents.
