Group B Strep (GBS)
A detailed guide on symptoms, mother & baby complications, treatments, and medical triggers.
What is Group B Strep (GBS)?
An infection caused by Streptococcus agalactiae bacteria. It is a common bacterium found in the digestive and lower reproductive tracts of 25% of healthy adult women, which can be passed to the baby during vaginal delivery.
Key Symptoms & Warning Signs
Knowing what warning signs to identify can help catch and manage this condition early. Keep in mind that some conditions are entirely asymptomatic and only detected during routine clinical screenings.
- ⚠️ No symptoms for the mother (GBS is colonizing, not an active infection for the mother)
- ⚠️ High fever or difficulty feeding in newborns (signs of GBS infection in baby)
Maternal & Fetal Risks
Unmanaged conditions can introduce health complications for both the expectant mother and the developing fetus. Proper diagnosis and clinical compliance mitigate these risks.
Risks to the Mother 👩⚕️
Uterine infection (chorioamnionitis) or urinary tract infections.
Risks to the Baby 👶
Sepsis (blood infection), pneumonia, meningitis, and developmental issues if untreated during labor.
Treatment & Clinical Management
Treatment protocols are tailored to the severity of the condition, your gestational age, and general fetal parameters. Common management strategies include:
Routine screening swab of the vagina and rectum at weeks 36 to 37
Intravenous (IV) antibiotics (usually penicillin) during active labor
Newborn monitoring for 24-48 hours after birth
🚨 When to Call Your Healthcare Provider
Call your OB/GYN immediately when your water breaks or active labor starts, especially if you have tested positive for GBS, so antibiotic treatment can begin on time.
Frequently Asked Questions
Can I take oral antibiotics before labor to cure GBS?
No, oral antibiotics taken before labor are not effective because the bacteria naturally colonizes the tract and will return before delivery. GBS must be treated with IV antibiotics during active labor.
What if I have a scheduled C-section and am GBS positive?
If you are having a C-section before your water breaks or labor begins, the risk to the baby is extremely low, and antibiotics are generally not required.
How does GBS affect the baby after birth?
Early-onset GBS occurs within 24 hours of birth, causing breathing problems and fever. Late-onset occurs weeks later and can lead to meningitis. Antibiotics during labor reduce early-onset risk by 80%.
