This section elaborates on the transmission pathways of GBS, which can significantly affect both the mother and her unborn child.
Vertical Transmission Mechanisms
Vertical transmission refers to the passage of pathogens from the mother to the infant during various stages of pregnancy and childbirth. The following are the primary mechanisms through which GBS can be transmitted:
- Intrapartum Transmission: The most common mechanism occurs during labor when the infant comes into contact with GBS colonized in the birth canal. In approximately 25% of women, GBS is present in the vagina and rectum. If these women are not identified and treated, newborns are at risk of GBS disease.
- Transplacental Transmission: Although less common, GBS can be transmitted through the placenta during pregnancy, particularly if there is infection in the amniotic fluid, leading to higher risk for the fetus.
- Postnatal Transmission: After birth, GBS can be passed to the infant through direct contact with colonized caregivers or surfaces. This is why hygiene practices post-delivery are imperative.
Signs of vertical transmission may not appear immediately, but symptoms can develop within the first week of life, emphasizing the need for monitoring.
Risk Factors for Transmission
Certain factors can enhance the risk of GBS transmission from mother to child. Understanding these risk factors helps in identifying at-risk pregnancies and planning appropriate interventions. These include:
- Maternal GBS Colonization: The presence of GBS in a mother's body increases the likelihood of transmission during delivery. Women who test positive for GBS late in pregnancy should be considered high-risk.
- Preterm Birth: Babies born before 37 weeks are more vulnerable to GBS infection due to immature immune systems and possible exposure to the bacteria in an unprepared birth canal.
- Prolonged Rupture of Membranes: If the amniotic sac breaks more than 18 hours before delivery, the risk increases. Prolonged exposure may allow GBS to ascend and infect the uterus.
- Multiple Vaginal Examinations During Labor: Each examination can introduce bacteria or disturb colonized areas, increasing the odds of transmission to the infant.
- Maternal Fever During Labor: A temperature of 100.4°F (38°C) or higher may suggest an infection, increasing the risk for GBS transfer.
It is crucial for expecting mothers to be aware of these risk factors and discuss them with healthcare providers to devise a plan for managing GBS through appropriate screening and treatment options.
