Newborn babies can get the bacteria:
- Before birth, the fetus may breath in fluid around it
- During delivery, from the birth canal
- After birth, by touch, often with the mother

Black newborns are at increased risk. It is also common in mothers who give birth at a young age.
Things that may raise your baby's risk are:
- An infected mother who doesn’t get treated before birth
- Mother had a prior baby with GBS infection
- Mother has a urinary tract infection due to GBS.
- Labor or water breaking before 37 weeks
- Water breaking for 18 hours or more before birth
- Mother has a fever during labor
- Frequent pelvic exams during labor
- Use of tools that check the fetus
A pregnant woman usually doesn’t have symptoms.
The newborn may have
- Breathing problems
- Not eating well
- Crying a lot
- Problems waking
GBS colonization may be found during an office visit. Testing should be done about one month before the baby is due.
Your baby may have:
- Blood tests
- Urine tests
- Spinal fluid test
For the Mother
If you have GBS or are at high risk, your doctor will give you antibiotics. This will lower the risk that your baby will get sick. It must be given at least four hours before birth. Some babies can still get GBS.
If GBS is found in the urine, women should be treated for this infection with antibiotics.
For the Baby
A newborn who may have GBS may be need a couple of extra days of medical care. Blood and urine tests may be done. Antibiotics will be given.
Follow these steps:
- Get screened for GBS at 35-37 weeks.
- Talk to your doctor about taking antibiotics during birth if you have not been tested but are at risk.
