How do I safely manage herpes during pregnancy to protect the baby’s skin? 

Managing the herpes simplex virus during pregnancy is a priority for ensuring the health and safety of the infant. While many women with a history of herpes have healthy pregnancies and deliveries, the virus requires careful clinical monitoring to prevent transmission to the baby during birth. Because the immune system of a newborn is not yet fully developed, exposure to the virus can lead to serious complications. Following established healthcare pathways in the United Kingdom ensures that both the mother and the baby receive the appropriate care and protection throughout the pregnancy and delivery process.

Distinguishing between primary and recurrent infections 

The risk to the baby depends largely on whether the mother develops the virus for the first time during pregnancy or has a history of previous outbreaks. If you get genital herpes for the first time in the last six weeks of pregnancy, there is a high risk you will pass it to your baby during a vaginal birth. This is because the body has not had enough time to produce the antibodies that help protect the baby. In contrast, if you have a history of recurrent herpes before becoming pregnant, your immune system already has antibodies that are passed to the baby through the placenta, significantly reducing the risk of transmission during delivery. 

Clinical management in the third trimester 

To reduce the risk of an active outbreak at the time of birth, healthcare professionals often recommend a course of antiviral medication starting around the thirty sixth week of pregnancy. The Royal College of Obstetricians and Gynaecologists guidelines suggest that daily antiviral management in late pregnancy can help prevent recurrences and reduce the need for a caesarean section. This suppressive therapy works by keeping the virus in a dormant state during the final weeks of gestation, ensuring the skin remains clear and reducing the likelihood of asymptomatic viral shedding during labour. 

Delivery decisions and viral outbreaks 

The method of delivery is carefully considered if an active outbreak is present when labour begins. If there are visible blisters or sores on the genitals at the time of birth, a caesarean section is often recommended to bypass the infected area and prevent the baby’s skin from coming into contact with the virus. However, if no sores are present and it is a recurrent infection, a vaginal birth is usually considered safe. Your midwife and obstetrician will perform a thorough examination and discuss the best options with you to ensure the safest possible outcome for the baby. 

Protecting the baby after birth 

Safety measures continue after the baby is born to prevent any accidental transmission from the mother or other family members. If you have an active cold sore on your lip, you must be extremely careful not to kiss the baby and to wash your hands thoroughly before any contact. Neonatal herpes is a very serious condition for young babies, so anyone with a cold sore should avoid close contact with the infant. Hygiene is the most effective tool in the postnatal period for keeping the baby’s skin and overall health protected from the virus while their immune system matures. 

Identifying symptoms in the newborn 

It is essential for parents to be aware of the signs of viral exposure in a newborn, as early intervention is critical. Symptoms of neonatal herpes can be subtle at first and may include the baby appearing lethargic, having a high temperature, or showing a lack of interest in feeding. You should also look for any small blisters on the baby’s skin, around their eyes, or inside their mouth. If a baby shows any of these signs, especially if there has been a known exposure to the herpes virus, you must seek medical attention immediately. 

Working with your clinical team 

Open communication with your midwife and GP throughout your pregnancy is the best way to manage the risks associated with the herpes virus. You should inform your care team about your history with the virus, even if you have not had an outbreak for a long time. This allows them to create a tailored care plan that includes the necessary monitoring and management to protect both you and your baby. Being proactive about your health ensures that all necessary precautions are in place well before your due date. 

Conclusion 

Safely managing herpes during pregnancy involve clinical monitoring, the potential use of antiviral medication in the third trimester, and careful planning for delivery. By understanding the risks and following professional guidance, the chances of passing the virus to the baby are significantly minimised. Consistent hygiene and awareness of symptoms after birth further ensure the infant’s safety. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
