  The highest incidence of bacteremia was found in patients aged less than 1 year (57.9%), and the majority of patients (30.5%) were infants aged less than 1 month. Staphylococcus aureus was the most common isolated pathogen (18.7%). Prematurity was associated with 13.2% of the cases, and respiratory tract infection (10.1%) and fever (76.1%) were chief complaints.
