Overview

Group B Streptococcus (GBS) causes invasive disease primarily in infants, pregnant or postpartum women, and older adults, with the highest incidence among young infants.[1] Before active prevention was initiated, an estimated 7,500 cases of neonatal GBS disease occurred annually in the United States.[2] Striking declines in disease incidence coincided with increased prevention activities in the 1990s,[3] and a further reduction occurred following the issuance of the recommendation for universal screening in 2002.[4] However, GBS disease remains the leading infectious cause of morbidity and mortality among newborns in the United States.[1][5] The continued burden of disease and newly available data relevant to early-onset GBS disease prevention from the fields of epidemiology, obstetrics, neonatology, microbiology, molecular biology, and pharmacology prompted revision of the guidelines for early-onset GBS disease prevention.[6]
