What are the signs of GBS infection in a baby?


  • Most babies who develop GBS infection become unwell during their first week of life – this is known as early-onset GBS infection.
  • Most commonly babies will become unwell within 12-24 hours of birth.
  • Although less common, GBS infection can affect babies until they are 3 months old. This is known as late-onset GBS infection.
  • The Royal College of Obstetricians and Gynaecologists states that babies with early-onset GBS infection may have the following symptoms:
    • Grunting/ noisy breathing/ moaning
    • They may seem to be working hard to breathe when you look at their chest or tummy, or not be breathing at all.
    • Be sleepy and/or unresponsive.
    • Be crying inconsolably.
    • Be unusually floppy.
    • Not feed well or not keep milk down.
    • Have a high or low temperature and/or skin that feels too hot or cold.
    • Have changes in their skin colour (including blotchy skin).
    • Have an abnormally fast or slow heart rate or breathing rate.
  • If you notice any of these signs or symptoms or are worried about your baby, then you should seek urgent medical attention and mention GBS.
