Group B Strep (GBS)

GBS is bacteria that is commonly found in the vagina (approximately 30% of women) and is known to come and go at any time. Although it causes no harm to the mother, it can cause serious infection in the newborn. There are different screening methods, one of which is a vaginal swab at 36 weeks gestation. If this is positive then you will be given intravenous antibiotics when you’re in labour or if you rupture your membranes (break your waters). This reduces the risk of infection to the newborn to 1 in 1000.
