Perinatal Group B Streptococcal Diseasecomes from an intrauterine infection of the fetusfrom the spread of Group B Streptococcusfrom the vaginaof a colonized woman who is typically asymptomatic. Medical studiesshow that prenatalscreening cultures reduce the incidence of Perinatal Group B Streptococcal Disease. Studies of single institutions or health maintenance organizationsshow institutions with a culture-based screening policy have close to 90% of delivering women with documented GBS screening, and close to 90% of GBS-positive women received intrapartum antibiotics. ^{[{{fullurl:Template:FULLPAGENAME}}#endnote_Hafner]} Cost-effectiveness analyses of the screening- and risk-based strategies have indicated that although the initial costs associated with specimen collection and processing make the screening strategy more expensive than the risk-based approach, the overall cost savings due to disease prevention do not differ importantly between strategies. ^{[{{fullurl:Template:FULLPAGENAME}}#endnote_Pediatrics]}
