This retrospective study was done to determine the incidence of neonatal Group B streptococcal sepsis among newborn between 1998 and 2010. Among 107,692 babies born during this period, the overall incidence of Group B streptococcal sepsis was 0.76/1000 live births with the incidence of early onset sepsis being 0.68 (95% confidence interval: 0.52-0.83)/1000 live births. The overall rate of early onset sepsis decreased to 0.55/1000 live births with introduction of intrapartum antibiotic policy.
