For anyone pregnant and living with herpes simplex virus (HSV), especially genital HSV, it’s natural to feel a mix of anxiety, uncertainty, and a deep sense of responsibility. Concerns about how HSV might affect the pregnancy, the baby, or the delivery are valid—and shared by many. The thought of potential complications like neonatal herpes or early labor can be deeply unsettling.
What’s important to know is that while herpes can lead to complications in certain cases—particularly if a first-time (primary) infection occurs late in pregnancy—most people with HSV go on to have healthy pregnancies and healthy babies. The greatest risk arises when someone contracts HSV for the first time during the third trimester. In those cases, because the body hasn’t had time to build protective antibodies, there’s a higher chance of the virus being transmitted to the baby during birth.
However, that scenario is not the norm. Most people living with HSV are managing a recurrent infection, which carries a much lower risk—around 1%—of neonatal transmission. That risk is further reduced with proper care. Suppressive antiviral therapy, close monitoring in the third trimester, and thoughtful delivery planning are all highly effective at keeping both mother and baby safe.
This guide walks through the stages of pregnancy—from the early weeks to labor and delivery—with practical, evidence-based strategies to manage herpes confidently and safely. With awareness, early communication with healthcare providers, and a personalized approach to care, it’s entirely possible to have a pregnancy that is not just safe but also empowering.
Step One: Talk to Your Healthcare Provider Early
The first prenatal visit sets the tone for your pregnancy journey—and it’s the ideal time to talk openly with your provider about herpes. Whether it’s a longstanding diagnosis or a recent one, sharing your HSV status early allows your care team to create a plan tailored to you and your baby’s well-being. This isn’t just a matter of medical documentation—it’s a proactive step that significantly reduces the risk of complications like neonatal herpes, particularly in cases where the infection is new or unmanaged.
If you’ve had outbreaks in the past, your doctor can factor that history into when (and if) to begin antiviral medication in the third trimester. If you’ve never discussed HSV with a provider before, now is the time—especially if you suspect past exposure. The more information your care team has, the more effectively they can guide you through a healthy pregnancy and delivery.
It’s also important to clarify whether your herpes is oral or genital, and whether it’s caused by HSV-1 or HSV-2. While both types can cause genital infections, they behave differently when it comes to shedding and recurrence—details that matter when making decisions about medication and birth planning. HSV-2 is more likely to cause repeat outbreaks, which may influence the timing of antiviral treatment or the decision to consider a cesarean delivery if active symptoms are present at labor.
For those who haven’t had obvious symptoms but believe they might have been exposed to HSV, type-specific blood testing can offer valuable insight. Many people carry the virus without knowing it, and serologic testing can help identify whether you’re already immune or still at risk—particularly important if your partner is known to have HSV. This information can be used to guide protective strategies throughout pregnancy and delivery.
Early conversations lead to better outcomes. Starting the dialogue now gives you time to prepare, adjust, and move through your pregnancy with clarity and confidence.
Managing Herpes in Pregnancy: A Trimester-by-Trimester Approach
Every stage of pregnancy brings different needs and considerations, and managing herpes is no exception. Whether you’ve had HSV for years or were recently diagnosed, knowing how to approach each trimester can help reduce anxiety and ensure the best outcomes for you and your baby. Here’s how management evolves over time.
First Trimester: Build the Foundation
The early weeks of pregnancy are filled with new emotions and adjustments. For those with HSV, it’s reassuring to know that herpes outbreaks in the first trimester are rarely dangerous to the fetus. The risk of transmitting the virus is extremely low at this stage unless a first-time infection occurs near the time of delivery.
That said, it’s a good time to focus on supporting your immune system. Emotional stress, lack of sleep, and poor nutrition can all contribute to outbreak frequency. Prioritizing rest, staying hydrated, and eating well are not just general pregnancy advice—they can also help keep HSV in check.
If outbreaks do happen, it’s worth knowing that early research has found no increased risk of birth defects with first-trimester use of antivirals like acyclovir or valacyclovir. While treatment decisions should always be made in partnership with your provider, having these options on the table can offer peace of mind.
Second Trimester: Monitor and Plan
As your pregnancy progresses, the focus shifts to preventing outbreaks that could affect labor. This is a good time to track your symptoms more closely, especially if you tend to have frequent recurrences. Establishing your typical outbreak pattern helps your healthcare provider determine the best time to start antiviral suppression.
If you’ve been having regular outbreaks, your provider may recommend starting treatment earlier than the standard timeline. Reassessing your care plan mid-pregnancy allows for flexibility and ensures your body is well-prepared heading into the final stretch.
Third Trimester: Prepare for Delivery
Most providers recommend starting suppressive antiviral therapy—usually valacyclovir or acyclovir—at 36 weeks. This step significantly reduces the likelihood of viral shedding or an active outbreak during labor, two of the primary concerns when it comes to protecting the baby during delivery.
The presence of visible sores or warning symptoms (like tingling or burning) at the time of labor usually leads to a recommendation for a cesarean delivery to avoid neonatal exposure. However, if you’re symptom-free and shedding risk is low, vaginal delivery is often considered safe, even for those with a known HSV diagnosis.
By taking it trimester by trimester, managing herpes in pregnancy becomes less overwhelming—and more about staying informed, responsive, and supported.
Delivery Planning: Safe and Informed Choices
When it comes to giving birth, people living with herpes often have one pressing question: Can I have a vaginal delivery? The answer, in most cases, is yes.
Vaginal Delivery Is Often Safe
For individuals with a history of genital herpes, vaginal birth is typically safe as long as there are no active lesions or warning symptoms—such as tingling or itching—at the time of labor. Medical guidelines and research consistently support this, recognizing that the risk of transmitting the virus during an asymptomatic delivery is very low. Starting suppressive antiviral therapy at 36 weeks further reduces the likelihood of viral shedding during birth.
Even for those who are seropositive—meaning they have developed antibodies to HSV—vaginal delivery remains a recommended and safe option in the absence of symptoms. With appropriate management, the vast majority of births proceed without complication.
When Cesarean Delivery Becomes Necessary
Cesarean birth is advised when active herpes lesions or prodromal symptoms are present at the onset of labor. This is to minimize the risk of neonatal herpes, which, while rare, can be serious. While not every case of transmission can be prevented through surgical delivery, it remains the best option when there are signs of active infection.
People who acquire herpes for the first time in the third trimester—particularly a primary genital infection—are at increased risk of passing the virus to their newborn, since their immune system hasn’t yet produced protective antibodies. In these situations, a planned C-section may be recommended even in the absence of visible symptoms.
Suppressive Therapy Makes a Difference
One of the most effective ways to reduce the need for a surgical delivery is through suppressive antiviral therapy. Starting medication like valacyclovir or acyclovir at 36 weeks significantly lowers the chance of outbreaks or viral shedding during labor. In fact, research shows that for those with a first-episode infection during pregnancy, suppressive therapy can reduce C-section rates from over one-third to nearly zero.
Ultimately, delivery decisions are made in partnership with a healthcare provider, based on current symptoms and the timing of infection. With open communication and the right care plan, people living with herpes can have safe, supported, and empowered birth experiences.
Partner Considerations: Shared Responsibility and Communication
When navigating pregnancy with herpes, it’s not just about managing the virus—it’s also about protecting your partner and nurturing mutual trust. If you’re in a relationship where one partner has HSV and the other does not (a discordant couple), taking steps to reduce the risk of transmission is especially important, both for the health of your partner and your peace of mind.
If Your Partner Is HSV-Negative
For those newly diagnosed or living with HSV during pregnancy, using barrier protection such as condoms remains a key preventative measure. While not foolproof, condoms significantly lower the chance of transmission—especially when used consistently and correctly. This is particularly crucial if your partner is HSV-negative, as primary infections during pregnancy (for either partner) carry higher health risks.
In cases where one partner is seronegative, daily suppressive antiviral therapy for the partner with HSV can offer added protection. Suppression reduces both the frequency of outbreaks and asymptomatic shedding, making transmission less likely and creating a safer dynamic for the duration of the pregnancy.
Oral-Genital Contact and HSV-1
Many people don’t realize that HSV-1, commonly associated with cold sores, is now a leading cause of genital herpes—often spread through oral-genital contact. If your partner has an active cold sore, it’s important to avoid oral sex until the area is fully healed. This is especially critical during pregnancy, as a first-time genital HSV-1 infection in the third trimester poses a higher risk of neonatal herpes.
Even without visible symptoms, HSV-1 can be transmitted through viral shedding. Using barrier protection or abstaining from oral-genital contact during suspected shedding periods can help reduce this risk.
Communicate and Collaborate
Perhaps most important of all is honest, open communication between partners. Conversations about HSV status, boundaries, and protective strategies aren’t always easy, but they are empowering. When both partners feel informed and involved, it creates a sense of shared responsibility and respect.
Collaborating on decisions about sexual activity, antiviral treatment, and delivery planning helps ensure that both people feel supported. It also increases adherence to safety strategies, improving outcomes for everyone—especially the baby.
In relationships where HSV is part of the picture, compassion and clarity go a long way. With a united approach, you can navigate pregnancy with confidence and connection.
Emotional Well-being During Pregnancy
Managing herpes during pregnancy isn’t just a medical experience—it’s an emotional one. For many, an HSV diagnosis or the responsibility of managing a known condition during this time can bring up feelings of anxiety, shame, or isolation. These emotions are deeply human and completely valid, especially in a world where stigma around HSV still lingers.
Some people feel overwhelmed by fears of harming their baby or being judged by others. This can be even more intense for those who are newly diagnosed, younger, or navigating pregnancy for the first time. When social support is lacking, these feelings can grow heavier, contributing to stress and emotional fatigue during a time that’s already full of change.
Support Makes a Difference
The good news is that emotional health can be supported just like physical health. Having someone to talk to—a therapist, a trusted friend, a partner—can help ease the emotional weight. Connecting with others who understand the experience, like members of HSV-positive communities or online support groups, can also offer comfort and reduce feelings of isolation. In these spaces, people often find validation, shared wisdom, and reminders that they’re not alone.
Therapy can be especially helpful if you’re grappling with anxiety or shame related to HSV. A professional can help you unpack fears, challenge internalized stigma, and build strategies for staying grounded throughout your pregnancy. Personalized, compassionate care is a powerful tool for emotional resilience.
You Are Not Alone—and You Are Not “High Risk” Because of HSV
One of the most reassuring truths is this: most people with genital herpes have healthy pregnancies and healthy babies. Having HSV doesn’t automatically make your pregnancy “high risk.” The exception is if a primary infection occurs late in pregnancy, in which case your healthcare provider will work closely with you to manage it safely.
With medical support, suppressive therapy, and thoughtful delivery planning, the risk of transmitting herpes to a baby is low. And just as importantly, you deserve to feel calm, informed, and empowered—not blamed or burdened.
Pregnancy is a profound and personal journey. HSV is just one part of it—not the defining feature. With care and community, you can move through this time with strength, confidence, and peace of mind.
After Birth: Protecting Your Baby
Bringing a new baby into the world is a time of profound joy—and naturally, a time of heightened vigilance. For parents living with HSV, understanding how to protect a newborn after birth is key to feeling empowered and prepared. The good news: with basic precautions and a little planning, the risk of postnatal transmission remains very low.
When the Risk Is Highest
The majority of neonatal herpes cases happen not after birth, but during delivery—specifically when a birthing parent has a new or active genital HSV infection at the time of labor. The risk of passing the virus to the baby is significantly higher (30–50%) in cases of primary infection acquired late in pregnancy. By contrast, the risk drops to under 1% when HSV is a recurrent infection and well-managed.
That’s why careful delivery planning matters. If lesions or symptoms are present during labor, a cesarean birth is typically recommended to reduce the chance of exposure.
Protecting Against HSV-1 After Birth
Once home, another form of herpes—HSV-1, commonly known as cold sores—becomes a concern. HSV-1 can be passed through saliva and even small amounts of contact with a sore or infected skin. Anyone with a cold sore, including family members or visitors, should avoid kissing the baby or touching the baby’s face, hands, or open skin. Even casual contact can pose a serious risk if HSV is transmitted to a newborn’s still-developing immune system.
Though rare, cases of severe or even fatal HSV-1 infection have occurred in babies exposed to infected caregivers. Practicing caution, especially in the first few weeks, is an essential part of keeping your baby safe.
The Importance of Hygiene and Awareness
Basic hygiene goes a long way in preventing transmission. Thorough handwashing—before feeding, diaper changes, or any skin contact—is a simple but powerful tool. If you or anyone around the baby has an active lesion, it’s best to avoid skin-to-skin contact altogether until it’s fully healed.
Also, keep a close eye on your newborn’s health. HSV in babies can sometimes present with subtle symptoms, mimicking common infections like sepsis. If you notice anything unusual—fever, lethargy, or unexplained skin lesions—reach out to a healthcare provider right away. Early treatment is key.
By staying informed, setting healthy boundaries with visitors, and trusting your instincts, you can confidently protect your baby and focus on bonding in those beautiful early days of life.
When to Call Your Doctor
Pregnancy brings a steady stream of bodily changes, and it can be hard to know what’s normal and what warrants medical attention. If you’re living with HSV—or at risk of acquiring it—there are specific signs that should prompt a call to your healthcare provider. Early intervention is not just protective; it’s powerful.
New Symptoms During Pregnancy
If you experience symptoms of genital herpes for the first time during pregnancy—especially in the third trimester—it’s important to seek medical care immediately. A primary infection during this stage carries a significantly higher risk of passing HSV to the baby during delivery. The earlier your provider can diagnose and begin antiviral therapy, the better the outcome for both you and your baby.
First-time HSV infections may be more intense than recurrent episodes. Symptoms like painful genital ulcers, flu-like illness, swollen lymph nodes, or general fatigue should never be ignored. Even if you’re unsure, it’s worth making the call to rule out any concerns.
If Your Partner Develops HSV Near Delivery
If your partner develops signs of HSV late in your pregnancy, it can change your own risk profile—particularly if you’re HSV-seronegative. Transmission from a newly infected partner is more likely during this window, and if contracted late, the risk to the baby increases. If this happens, it’s essential to inform your provider and discuss protective strategies, such as abstaining from sex or using condoms until delivery.
Type-specific testing may be advised to clarify your own HSV status and inform next steps. These kinds of conversations can feel awkward, but they’re essential for safe and informed care planning.
Signs of Neonatal Herpes After Birth
After your baby is born, stay alert for signs that may indicate neonatal herpes. Symptoms often appear within the first few weeks and can include fever, excessive sleepiness or fussiness, poor feeding, or small blisters or sores on the skin. These symptoms might resemble common newborn issues, but when HSV is a factor, prompt evaluation is crucial.
If you notice any of these signs, don’t wait—contact your baby’s doctor immediately. Neonatal herpes can progress quickly without treatment, but early use of antiviral medication like acyclovir can make a life-saving difference.
Knowing when to reach out for help is a core part of managing HSV in pregnancy and beyond. Trust your instincts, stay informed, and never hesitate to lean on your healthcare team—they’re there to support you and your baby every step of the way.
Moving Forward with Confidence and Care
Living with herpes during pregnancy can bring up a lot of questions, emotions, and decisions—but you don’t have to navigate any of it alone. With good information, early conversations with your provider, and thoughtful planning through each trimester, it’s entirely possible to protect your baby and care for yourself along the way.
Most people with HSV have safe, healthy pregnancies. The key is being proactive: understanding your risks, managing symptoms, and creating a delivery plan that fits your unique experience. It’s also about honoring the emotional side of this journey—acknowledging any fears or shame without letting them define your pregnancy. You are more than a diagnosis, and you deserve support that sees the full picture of who you are.
