Overview
Natural History
GBS in Neonates
Most newborns with early-onset disease have symptoms on the day of birth. Babies who develop late-onset disease may appear healthy at birth and develop symptoms of group B strep disease after the first week of life. Infants with early-onset GBS disease generally present with respiratory distress, apnea, or other signs of sepsis within the first 24--48 hours of life.[1] The most common clinical syndromes of early-onset disease are sepsis and pneumonia; less frequently, early-onset infections can lead to meningitis.
GBS in Pregnancy
GBS colonization during pregnancy can be transient, intermittent, or persistent. Although some women with GBS colonization during a pregnancy will be colonized during subsequent pregnancies, a substantial proportion will not.[2][3] In the absence of any intervention, an estimated 1%-2% of infants born to colonized mothers develop early-onset GBS infections.[4][5]
