Pregnancy: When to Treat Group B Strep

Your physician is following the recommendations of the American College of Obstetricians and Gynecologists as well as the Centers for Disease Control. The recommendations come from the many studies showing that labor is the best time to treat the baby and mother. When mothers are treated during pregnancy, they may be exposed to penicillin-resistant strains of other bacteria, and the recurrence rate is high.

From an individual viewpoint, many women want to be treated. It is controversial, but some physicians will do it. Whether or not Group B strep causes preterm labor and premature rupture of the membranes is questionable and needs further research.

Your local infectious-disease officer at your state department of health can be of help here, too.

Good luck.
