About Group B Strep (GBS)

Group B Streptococcus is also known as GBS, Strep B or group B Strep. It is a common bacteria that normally causes no harm. In the UK, 1 in 4 women carry group B Strep in their vagina and rectum. You’re unlikely to know you carry it.

If you carry group B Strep, your baby may be exposed to it around labour and birth. While most babies won’t be affected, there is a very small chance of your baby becoming seriously ill or even dying. In extremely rare cases group B Strep infection can cause miscarriage, early labour or stillbirth.

For more information about group B Strep, visit the Royal College Obstetricians and Gynaecologists  (RCOG) website.
