A positive group B streptococcus can lead to a normal labor. A woman who is positive for group B streptococcus has a risk of the fetus becoming infected with group B streptococcus as it passes through the birth canal, which may result in neonatal sepsis, lung infections, and other adverse outcomes. When found positive for group B streptococcus, there is no special treatment during pregnancy, and antibiotics are selected for use according to the drug sensitivity when water breaks or when labor is imminent. Intravenous application of penicillin antibiotics after water breakage and before labor can have a preventive effect, and if the newborn does not have any abnormal manifestations, no special treatment is usually needed. It is recommended that mothers should choose regular hospitals, and have a professional doctor choose a reasonable delivery method according to the examination results and labor indications.
