Herpes and Marriage: Relationships, Pregnancy, and Children

Finding out that you or your partner has herpes can be frightening, especially when marriage or children are on your mind. This guide answers the questions many people are afraid to ask: whether someone with herpes can marry, how the virus passes between partners, how to lower that risk, and what herpes means for pregnancy, childbirth, and newborns.

Can Someone With Herpes Get Married?

Yes. Having herpes does not prevent anyone from marrying, having a loving and intimate relationship, or having children. Herpes is a common, long-term infection: the WHO estimates that 64% of people under 50 have HSV-1, and 13% of people aged 15 to 49 have HSV-2. Most of them have no symptoms or only mild ones, and many don't know they have it.

What herpes does call for is honesty, a few practical precautions, and medical advice at key moments — especially before and during pregnancy. No method makes the risk of passing it on zero, but together they lower it.

What Is Herpes?

Herpes is caused by the herpes simplex virus (HSV). After the first infection, the virus stays in the nerve cells for the rest of your life. It can remain inactive (dormant) for long periods and become active again from time to time.

HSV-1 and HSV-2: Oral and Genital Herpes

• HSV-1 usually spreads through oral contact and causes cold sores around the mouth. Most adults have it, usually since childhood. HSV-1 can also cause genital herpes through oral-genital contact.
• HSV-2 spreads through sexual contact and is the main cause of genital herpes.

The type matters for couples: the CDC notes that recurrences and symptom-free shedding are much less frequent with genital HSV-1 than with genital HSV-2.

Symptoms, Dormancy, and Recurrences

Many people never notice symptoms. When symptoms appear, they can include painful blisters or open sores around the mouth, genitals, or anus, often preceded by tingling, itching, or burning. Genital herpes can also cause pain when passing urine (see our guide to burning urination). A first episode can come with fever, body aches, and swollen glands.

Later outbreaks (recurrences) are usually shorter and milder than the first. Triggers can include illness, fever, stress, menstruation, and sun exposure.

Herpes Is Not Shingles

Shingles (herpes zoster) is a different infection, caused by the chickenpox virus (varicella-zoster virus), not herpes simplex. Its painful rash appears on one side of the body only. Because the rash can occasionally appear on the genitals, people sometimes confuse the two — but shingles is a different virus, and having it says nothing about genital herpes.

Does a Herpes Diagnosis Mean Someone Was Unfaithful?

No — a herpes diagnosis cannot prove infidelity, and it says nothing about hygiene or morals. The virus can stay silent for years. The NHS notes that symptoms "might not appear for weeks or even years after you're infected," and that testing cannot tell you how long you've had herpes or who you got it from.

A first outbreak during marriage may come from an infection acquired long before the relationship began, by either partner, without anyone knowing. Many people also carry HSV-1 from childhood, which can later cause genital herpes through oral sex. Blaming each other is rarely accurate and rarely helpful.

How Does Herpes Spread Between Partners?

Herpes spreads through direct skin-to-skin or mucous-membrane contact with an area where the virus is present:

• vaginal, anal, or oral sex
• kissing or other contact with a cold sore
• oral sex from a partner with oral herpes, which can cause genital herpes
• touching a sore and then touching the genitals or another person

Herpes can spread without visible sores. The virus is most contagious from the first tingling of an outbreak until the sores have completely healed, but it can also be shed from skin that looks normal. The CDC states that most genital herpes infections are passed on by people who don't know they're infected or have no symptoms at the time.

The risk of symptom-free transmission is highest early on. The CDC says symptom-free shedding of HSV-2 is most frequent in the first 12 months after infection, but still happens from time to time even years later. The NHS describes the risk as highest in the first 6 months and rare after 2 years. Sources differ on how low the risk eventually becomes, which is why the precautions below remain worthwhile.

What doesn't spread herpes: the CDC and NHS state that you can't get herpes from toilet seats, swimming pools, bedding, towels, or sharing cutlery.

How Can Couples Lower the Risk of Transmission?

Each of these measures lowers the risk; combining them lowers it further.

About suppressive treatment: in a randomised trial of 1,484 heterosexual, monogamous couples in which one partner had symptomatic genital HSV-2, daily valacyclovir taken by that partner for 8 months reduced symptomatic transmission by about three-quarters and new infections overall by about half (1.9% compared with 3.6%). Both groups were also counselled and offered condoms. The CDC notes there is no equivalent evidence yet for genital HSV-1 or for people whose infection was found only on a blood test.

About condoms: the CDC says condoms are less effective at protecting men from infection than women, while the pooled analysis found similar protection for both. Either way, condoms help but are not complete protection.

If both partners have the same virus: according to the WHO, people who already have HSV-1 are not at risk of being reinfected with HSV-1, though they can still acquire HSV-2.

What If Only One Partner Has Herpes?

When one partner has herpes and the other doesn't, a doctor can help you talk through:

• which type of virus is involved (HSV-1 or HSV-2) and where (mouth or genitals)
• how often outbreaks happen, and whether daily suppressive treatment makes sense
• whether the other partner already carries the same virus

Testing has real limits. If there's a fresh sore, a swab test (PCR) is the most reliable way to confirm herpes and its type. Blood tests look for antibodies and can help in some situations — for example, the CDC says a type-specific HSV-2 blood test can be offered to the partner of someone with genital herpes. But blood tests:

• are not recommended as routine screening for everyone without symptoms
• can give false-positive results, especially with low positive values, so results may need confirming
• can miss a recent infection; after a recent possible exposure, the CDC advises repeating the test 12 weeks later
• can't show whether HSV-1 is in the mouth or the genitals, or when the infection happened

The CDC also advises against antiviral pills for the partner without herpes as a prevention method, because there's no evidence that this works. Don't diagnose yourself or take antiviral medicine without medical advice.

How to Talk About Herpes With Your Partner

Telling a partner or future spouse can feel hard, but it allows you to make decisions together. It can help to:

• choose a calm, private moment, not during intimacy
• share the facts: herpes is common, manageable, and often silent
• explain the precautions you can take together
• see a doctor together if you have questions about testing or treatment

The CDC recognises that a herpes diagnosis can cause significant distress, and counselling is a core part of care. If worry or guilt is affecting your relationship or daily life, a clinical psychology specialist or your doctor can help; our guide to anxiety explains the signs that it's time to get support. If you're preparing for marriage, our guide to premarital screening in Jordan explains the separate blood tests that couples usually take.

Can a Person With Herpes Have Children?

Yes. Herpes is not listed by the WHO, CDC, or NHS as a cause of infertility, and their pregnancy guidance focuses on protecting the baby, not on difficulty conceiving. A few small studies have looked at possible effects of herpes viruses on sperm, but the evidence is limited and not established. If you have concerns about fertility, speak to a doctor.

What matters more is planning:

• Tell your obstetric clinician about any history of genital herpes — yours or your partner's. The CDC advises that both the team caring for the pregnancy and the team caring for the newborn should know.
• If only the male partner has genital herpes, ask your doctor how to lower the risk for the female partner while trying to conceive and throughout pregnancy, because a first infection in late pregnancy carries the highest risk for the baby.

Herpes in Pregnancy and Childbirth

The NHS states that women who had genital herpes before pregnancy can usually expect a healthy baby and a vaginal delivery.

Why Timing Matters

The risk to the baby depends mainly on when the mother was first infected:

These figures come from the CDC. A large US study that followed more than 58,000 pregnant women also found that a first-episode infection at the time of labour was one of the strongest risk factors for neonatal herpes. The CDC also notes that many mothers of babies with neonatal herpes had no known history of herpes, which is why new symptoms in pregnancy always deserve attention.

If You Already Have Herpes Before Pregnancy

Your obstetric team may suggest antiviral treatment in the last weeks of pregnancy to reduce the chance of an outbreak at delivery. The CDC recommends starting it at 36 weeks of pregnancy for women with recurrent genital herpes. Your obstetric team will decide whether it applies to you. According to the CDC, this treatment reduces the need for a caesarean, but it may not protect against transmission in every case.

New Symptoms or a Possible Exposure During Pregnancy

See your obstetric team promptly — don't wait for your next routine visit — if during pregnancy you:

• develop genital sores, blisters, or tingling for the first time
• think you were exposed to herpes, especially in the third trimester

If a partner has genital herpes and you don't, the CDC advises avoiding vaginal sex during the third trimester. If a partner has cold sores and you don't, it advises avoiding receiving oral sex during the third trimester. A first infection in the second half of pregnancy is managed by specialists, so don't start or stop any medicine on your own.

Labour and Delivery: Is a Caesarean Always Needed?

No. A history of herpes alone is not a reason for a caesarean. At the start of labour, every woman should be asked about symptoms and examined:

• No sores and no warning symptoms: a vaginal delivery is usually possible.
• Genital sores at the start of labour: a caesarean is recommended. It lowers the risk but doesn't remove it completely. ACOG's patient guidance adds that a caesarean may also be needed if there are warning signs of an outbreak (tingling, burning, or pain where sores usually appear).
• A first infection in the third trimester: ACOG states that a caesarean may be offered, because the virus can be shed for longer after a first infection.

These decisions depend on many details and are made with your obstetric team. Don't plan your delivery method based on this article alone.

Herpes and Newborns

Neonatal herpes — herpes infection in a newborn — is rare: the WHO estimates about 10 cases for every 100,000 births worldwide. But it can be serious, which is why prevention and early treatment matter.

A baby can also catch HSV-1 after birth from someone with a cold sore. The NHS warns that kissing a baby while you have a cold sore can cause neonatal herpes. Anyone with a cold sore should avoid kissing newborns and should wash their hands before touching the baby.

Breastfeeding is usually safe: ACOG states that the virus is not passed through breast milk. Keep any sores covered, wash your hands before feeding, and don't feed from a breast that has a sore on it.

Treatment: What Antivirals Can and Can't Do

Antiviral medicines — acyclovir, valacyclovir, and famciclovir — are the mainstay of herpes treatment. They can be used:

• for an outbreak (episodic treatment): works best when started at the first tingling or as soon as sores appear, ideally within the first day
• every day (suppressive treatment): reduces the number of outbreaks by 70% to 80% in people who get them often, and lowers the risk of passing HSV-2 on to a partner

Antivirals don't remove the virus from the body: once you stop taking them, outbreaks can return. They are prescription medicines; your doctor will choose the medicine, dose, and duration — especially during pregnancy. Pain relievers, warm baths, and loose clothing can ease the discomfort of an outbreak.

What Should You Do After a Possible Exposure?

• Don't take antivirals "just in case." The CDC says there's no evidence that taking antivirals after an exposure prevents infection.
• Watch for symptoms. If sores or blisters appear, see a doctor or sexual health clinic quickly, ideally while the sores are fresh, so a swab test can confirm the diagnosis.
• Avoid sexual contact while you have any symptoms.
• If you're pregnant, tell your obstetric team promptly.
• About blood tests: an early blood test can be falsely negative; your doctor may suggest testing about 12 weeks after the exposure.

When Should You See a Doctor?

For pregnancy, an obstetrics and gynecology specialist manages herpes care, and an infectious disease specialist may be involved in complex cases.
