Kim S, et al. - The goal of this research was to inspect the effect of testing influenza in infants < 90 days with the fever. Furthermore, it examined the individuals’ characteristics to investigate which infants had to be considered for such testing. Diagnostic tests for influenza based on a detailed contact history were mandatory to gauge the cause of fever during the influenza epidemic season. Targeted testing for influenza could lead to a decrease in antibiotic use and admission rates in young infants.
