No! The treatment is simple: IV antibiotics in labor. This decreases the risk of transmission to your baby to less than 0.5 percent, and therefore is not a reason to expose yourself to the risks of a C-section.
With the problems that GBS infections can cause in newborns, you may wonder if having GBS is a reason to have a scheduled C-section. This is definitely not the case! Luckily, the treatment for GBS is simple: your doctor or midwife will order IV antibiotics to be given during your labor to decrease the chance of transmission. The drug of choice is usually penicillin, but if you are allergic an alternative will be used. The goal is to have the antibiotics in at least 4 hours before your deliver.
