The American Academy of Pediatrics, American College of Obstetricians and Gynecologists, and U.S. Centers for Disease Control and Prevention have established two methods to help reduce the risk of Group B streptococcal septicemia:

• Pregnant women are tested for group B streptococcus at 35 - 37 weeks into their pregnancy. If the bacteria are detected, women are given antibiotics through a vein during labor.
• Prenatal screening is not done, but a woman who meets certain risk factors is given antibiotics through a vein during labor.

Both sets of procedures are currently accepted as the standard of care.

Newborns who are at high risk are tested for GBS infection. They may receive antibiotics through a vein during the first 48 hours of life until blood culture results are available.

In all cases, proper hand washing by nursery caretakers, visitors, and parents helps prevent the spread of the bacteria after the infant is born.

An early diagnosis can help decrease the risk of some complications.
