The Risks of Group B Strep In Pregnancy

Group B Streptococcus, more commonly known as Group B Strep (GBS), is a bacterium that can infect babies. This bacterium is commonly found in the vaginal or rectal area — which is why mothers who undergo vaginal delivery can pass it on to their baby. 

Many people in the world carry group B strep (GBS) bacteria. While it usually isn’t harmful to adults, it has the potential to cause harm to your baby. What Is Group B Strep?  

The infection doesn’t have distinct symptoms, making it harder for mothers to know they may need treatment. However, most healthcare providers screen mothers for GBS per the American Academy of Obstetricians and Gynecologists (ACOG) recommendation on your 36th or 37th week of pregnancy. 

What Are The Risks of GBS In Babies?  

There are two types of GBS disease that can be found in babies: 

  • Early-onset GBS occurs during the baby’s first week of life. This Strep B infection can manifest as pneumonia. This type of GBS infection was quite common before ACOG began recommending treating the infection at the 36th or 37th week of pregnancy.   
  • Late-onset GBS manifests as meningitis and occurs during your baby’s first few months. Look for irritability and a bulging soft spot on the baby’s head. 

Most newborns infected with GBS seem unaffected by it. However, a percentage of babies for reasons we do not understand develop severe infections that can lead to life-threatening complications pneumonia and menigitis. In the US, an average of 930 babies get early-onset GBS and about 1,050 babies get late-onset GBS each year.  

What Are The Symptoms You Should Look Out For?  

It is rare to experience the symptoms of group B strep. While the elderly and those with medical conditions may have them, the best way for you to identify GBS is to get have a culture of a vaginal swab for the bacterium. 

However, babies infected with GBS have vague symptoms: 

  • Fever 
  • Difficulty feeding 
  • Irritability 
  • Sleepiness, and 
  • Breathing problems 


My experience is that a fever is sometime present, there is often difficulty breathing, and they may just seem to sleep constantly.
 

How do You Treat GBS?  

If your doctor finds traces of GBS, you will be treated with intravenous penicillin antibiotics every four hours during your labor and delivery. It is also likely that you will be given an oral antibiotic treatment if GBS is detected in your urinary tract. If you need to be treated for GBS, your baby should also be treated. 

Talk to Your Healthcare Provider  

As a part of your prenatal care, you should be screened for GBS, even if not until you are 37 or 38 weeks pregnant. You need to talk with your doctor about whether your GBS should be treated early in your pregnancy or at the standard 37 to 38 weeks. Physicians have their own protocols for dealing with GBS in pregnancy and you should find out what your physician prefers.  

GBS is the most common cause of neonatal death and it is both treatable and preventable.

Why should you support Rural Doc Alan?

Dr. Lindemann delivered 6000 babies for over 40 years with no maternal mortalities, no eclampsia, and no babies with cerebral palsy. He tells his story here of how he did this in a medical environment that really doesn’t do well with deliveries. He openly admits that much he learned about safe pregnancy came from his patients, not medical books. Donating here will help spread the word to women everywhere so they can learn about safe pregnancy.
