ACOG Committee Opinion No. 485: Prevention of early-onset group B streptococcal disease in newborns.

In 2010, the Centers for Disease Control and Prevention revised its guidelines for the prevention of perinatal group B streptococcal disease. Although universal screening at 35-37 weeks of gestation and intrapartum antibiotic prophylaxis continue to be the basis of the prevention strategy, these new guidelines contain important changes for clinical practice. The Committee on Obstetric Practice endorses the new Centers for Disease Control and Prevention recommendations, and recognizes that even complete implementation of this complex strategy will not eliminate all cases of early-onset group B streptococcal disease.
