Invasive Group B Streptococcal Disease (group B strep, GBS)

Group B Streptococcus (GBS) is a bacteria commonly found in the gut or genital tract (vagina). GBS can occasionally cause serious infections in vulnerable people, in particular newborn babies.

Invasive GBS (iGBS) is an infection where the bacteria is isolated or detected from a normally sterile body site, such as blood or spinal fluid.

iGBS disease in infants under 90 days is a notifiable disease in Ireland.
