Orfanos I, Alfvén T, Mossberg M, et al. - Via performing a retrospective study in previously healthy, full-term infants ≤ 60 days with fever without a source, researchers examined age- and gender-specific prevalence of serious bacterial infections (SBI: urinary tract infection, bacteremia, meningitis) among febrile infants ≤ 60 days. They included a total of 1,701 infants. Of these, 214 infants (12.6%) had an SBI, among which urinary tract infection represented the vast majority. Observations revealed a low prevalence of bacteremia and meningitis, particularly in the 29–60 days age group. No significant difference was observed between boys and girls.
