Can Herpes Be Transmitted To An Infant During Pregnancy Or Delivery

When babies contract herpes, its known as neonatal herpes. Also called birth-acquired herpes, neonatal herpes can happen if your baby is exposed to genital herpes during vaginal delivery.

Neonatal herpes is considered rare, but when it does happen, there can be serious complications, such as permanent injury to the babys nervous system, developmental disabilities, and death.

The risk to your baby is greatest if you acquire HSV for the first time during the third trimester of pregnancy. Thats because the levels of the HSV in your system will be highest during that time, and youll have fewer protective antibodies to pass on to the baby prior to delivery.

If you contract a genital herpes infection during the third trimester, the risk of passing the virus to your baby during delivery is

How Can I Make Sure I Dont Get Genital Herpes

If you test negative for genital herpes, the following steps can help protect you from getting a herpes infection during pregnancy:

  • If your partner has genital herpes, abstain from sex during any active herpes outbreak. Between outbreaks, use a condom from start to finish every time you have sexual contact, even if your partner has no symptoms. Consider abstaining from sex during the last trimester.
  • If you dont know whether your partner has genital HSV, you may wish to ask your partner to be tested. If your partner has genital or oral HSV, there is a very real chance that you may acquire it unless you take steps to prevent transmission.
  • Do not let your partner perform oral sex on you if your partner has an active cold sore . This can give you genital herpes.

Genital Herpes In Pregnancy

Herpes infections are only rarely passed on to babies during childbirth. If a woman already had herpes viruses inside her body at the start of pregnancy, there’s no reason why she shouldnt give birth naturally unless there are signs of an outbreak shortly before she goes into labor.

Herpes infections can be life-threatening for newborn babies. Because of this, many women who have genital herpes are afraid of passing herpes viruses on to their child while giving birth. But this only rarely happens.

How best to deal with genital herpes in pregnancy, and whether a natural birth is possible, will depend on

  • whether there are any signs of a genital herpes outbreak shortly before the birth and
  • when the woman became infected with the virus.

The risk of infection is much smaller if the woman already had genital herpes before, or at the beginning of, pregnancy. This is because her immune system will have had a chance to produce antibodies to the virus. The mother passes these antibodies on to her unborn child through her placenta, giving him or her a certain amount of protection.

Herpes Simplex Virus Infections

The herpes simplex virus causes a variety of infections, characterized by dormant periods with no symptoms and sporadic outbreaks of red, itchy, painful blisters. Generally, there are two types of herpes: genital herpes and oral herpes . However, herpes lesions from both types can be found anywhere on the body, including on the skin, mouth, eyes, and genitals.

Type 1 infections are most often found on the mouth, while type 2 infections tend to occur in the genital area.

Treatment Of Herpes In Pregnancy

The recommendation of the American College of Obstetricians and Gynecologists is to treat all primary outbreaks of genital herpes with antiviral medications, including primary outbreaks in pregnant women.

Acyclovir has the most data on the safety of use in pregnancy. A registry of over 1000 pregnant women who were exposed to acyclovir during early pregnancy suggests that acyclovir is most likely safe, as there were no increases in birth defects.

Most women who have a current outbreak of genital herpes, primary or recurrent, are usually advised to have a cesarean section to reduce the exposure of the infant to the herpes simplex virus. However, women with known herpes exposure usually take an antiviral medication in the third trimester to prevent outbreaksâand are able to safely deliver vaginally.

How Common Is Herpes Simplex

Approximately 80% of New Zealand adults have oral herpes and 30% have genital herpes.

You can get genital herpes if you have sexual contact with a partner who is infected with herpes, or if a partner who has an active cold sore performs oral sex on you. Most people with HSV dont know they are infected with herpes because they have no herpes symptoms, or symptoms too mild to notice.

If it’s your first outbreak of genital herpes, your baby may be more at risk because you haven’t had time to develop immune protection against the virus, which also helps protect the baby.

Some women experiencing an outbreak of genital herpes might be advised to have a caesarean. This would prevent the herpes virus passing from mother to baby during a vaginal birth. But most women in Australia with genital herpes do give birth safely to healthy babies vaginally.

It’s often recommended that women who have ever had genital herpes take antiviral tablets prior to the birth, even if the herpes isn’t active at the time.

Talk to your doctor or midwife about the best course of action for your situation.

How Is Herpes Diagnosed In Pregnancy


If you or your partner experience any of the above symptoms, check in with your doctor. A health care provider may be able to identify your sores via an exam, but a lab test is necessary to diagnose a case of genital herpes.

A sample is taken from the fluid inside a sore and then tested to see if it contains the virus and, if it does, what type of HSV is present. A blood test can check for antibodies and therefore diagnose HSV and its type but it cant determine how the infection was contracted or how long youve had the virus.

What Did The Research Team Do

The research team reviewed health records of pregnant women to see if treatment, treatment timing, or length of treatment reduced the risk of preterm birth and low birthweight.

Women who had genital herpes during pregnancy, doctors, and patient health organizations helped plan and conduct the study.

What Will A First Episode In Pregnancy Mean For Me And My Baby

If your first episode happens in the first 3 months of pregnancy, your baby is not more likely to have developmental problems and your risk of miscarriage is not increased. Later in pregnancy, a first episode should not affect your baby unless you are in labour .

If you go into labour less than 6 weeks after a first episode of genital herpes, your immune system wont have had time to produce antibodies to protect your baby. There is thus a high chance of passing the virus to your baby if you have a vaginal birth. If your first episode is earlier in pregnancy, your immune system will provide protection to your baby.

When a baby catches the herpes virus at birth, it is known as neonatal herpes. It can be serious but is very rare in the UK . Your baby will be looked after in a neonatal unit by a specialist team of doctors.

Which Babies Are Most At Risk

Can You Breastfeed With Herpes Virus ~ sopeldesign

Babies are most at risk from neonatal herpes if the mother contracts genital HSV for the first time late in pregnancy. This is because a newly infected mother does not have antibodies against the herpes virus, so there is no natural protection for the baby during birth. In addition, a new herpes infection is frequently active, so there is a real chance that the herpes virus will be present in the birth canal during delivery.

Firstly, make sure you tell your health care provider that you have genital herpes. Antiviral medication may be offered in late pregnancy to prevent or reduce recurrence. As labour approaches, inspect your genital area for any signs of a breakout and your health care provider will do the same. If you have an active outbreak, delivering by C-section instead of vaginally significantly reduces the high risk of transmitting the virus to your baby. Depending on the situation, you and/or your baby may be treated with anti-viral medications. If you have a vaginal delivery, some measures can prevent transmission, such as leaving membranes intact and avoiding instrument use and fetal scalp monitoring. After delivery, check the baby often for signs of infection, such as blisters, fever, or lack of appetite.

If your partner has HSV and you dont, use condoms every time you have sexual contact, even if your partner has no symptoms. Dont have sexual contact if your partner has an active outbreak and consider abstaining in the third trimester even if your partner doesnt have an active outbreak. It is recommended that you be tested early in pregnancy for HSV, and then again at 32-34 weeks gestation.

The greatest risk of infection to your baby happens if you acquire a new genital herpes infection late in pregnancy. In this case, delivering by C-section is the safest option.

Risks Of Herpes During Pregnancy

The major risk associated with herpes and pregnancy is neonatal herpes infections. These infections of the newborn are rare, but can be quite serious or even fatal. The biggest risk for neonatal herpes occurs for people who are newly infected during pregnancyparticularly near the time of delivery.

Cesarean section is recommended instead of vaginal delivery for people who have genital symptoms at the time of delivery. It is also recommended for people who are having prodromal symptoms that signal a likely outbreak. C-section has been shown to significantly reduce the risk of herpes transmission to the infant.
