Infants

An infant is at increased risk of developing group B strep disease if:

  • The mother carries group B strep in her body
  • The baby is born prematurely (earlier than 37 weeks)
  • The mother's water breaks 18 hours or more before delivery
  • The mother has an infection of the placental tissues and amniotic fluid (chorioamnionitis)
  • Group B strep bacteria have been detected in the mother's urine (bacteriuria) during pregnancy (either her current pregnancy or previous pregnancies)
  • The mother's temperature is greater than 100 F (38 C) during labor
  • The mother previously delivered an infant with group B strep disease

Adults

You're at increased risk of a group B strep infection if:

  • You have a medical condition that impairs your immune system, such as diabetes, HIV infection, cancer or liver disease
  • You're older than 65, particularly if you live in a nursing home
