About Group B Strep
Group B Streptococcus (GBS) is a normal bacterium which can be found in 20- 30% of adults in the UK, usually without any symptoms or side-effects. It’s most commonly found in our normal ‘gut flora’ and is also often found in the vagina of adult women.
GBS can occasionally cause infection, most commonly in newborn babies but also sometimes in women during pregnancy or after birth.
GBS is a recognised cause of preterm delivery, maternal infections, stillbirths and late miscarriages. Preterm babies are known to be at particular risk of GBS infection as their immune systems are not as well developed as those of full-term babies.
Overall, without preventative medicine, GBS infections affect an estimated 1 in every 1,000 babies born in the UK.
