Living with genital herpes means managing a common, lifelong skin condition. Most people have few or mild outbreaks, daily antiviral pills can make recurrences rare and lower the odds of passing the virus to a partner, and honest disclosure plus condoms keep relationships healthy.

The essentials: what genital herpes actually is
Genital herpes is caused by two related viruses — herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) CDC. After the first infection, the virus retreats into nerve roots near your spine and stays there for life. There's no cure. Antivirals don't erase the latent virus or change how often it reactivates once you stop taking them; they only control symptoms while you're on them. That sounds heavy, but in practice this is a skin condition that flares now and then and quiets down over the years for most people.
Which virus you carry matters. Genital HSV-2 recurs and sheds far more than genital HSV-1, so type-specific testing changes what you can expect. Increasingly, genital herpes is an HSV-1 infection picked up through oral sex — in one US young-adult cohort the share of new genital herpes caused by HSV-1 rose from 31% to 78% HSV-1 cohort. Genital HSV-1 recurs about once in the first year, while genital HSV-2 averages around four times a year. If you're sorting out an oral-versus-genital picture, our guide to oral herpes symptoms explains how HSV-1 behaves around the mouth.
Most people with herpes don't know they have it. Symptoms are absent or so mild they get mistaken for a razor nick, a yeast infection, or an ingrown hair, and the majority of HSV-2 infections are never diagnosed. People pass it without realizing they carry it.
Symptoms: first outbreak, recurrences, and the prodrome
A first outbreak is usually the worst one. You may get small blisters that break open into painful sores on or around the genitals, rectum, or mouth, and they typically take a week or more to heal. The first episode can come with flu-like symptoms — fever, body aches, and swollen glands — because your immune system is meeting the virus for the first time.
Recurrences are shorter and milder. Many people feel a warning sign hours to a day before, called a prodrome: tingling, itching, or a shooting ache in the area where a sore is about to appear. That prodrome is your moment to start episodic treatment or to avoid skin contact. Outbreak patterns differ by sex and anatomy, and the presentation can be subtle; our breakdown of genital herpes symptoms in women covers where lesions show up and what's easy to miss.
You can transmit herpes with no symptoms at all. People with HSV-2 shed virus on about 10% of days even when they never have an outbreak, and most of that shedding leaves no visible sore JAMA shedding study. Assuming "no sore, no risk" is the most common mistake people make, and disclosure and prevention matter even between flares.
Testing: the right test depends on whether you have a sore
If you have an active sore, the accurate test is a swab of the lesion sent for type-specific NAAT or culture, which also tells you whether it's HSV-1 or HSV-2 CDC testing. Go in while the sore is fresh; once it's healing, the swab is more likely to miss the virus. A clinic visit during an outbreak gets you the most reliable diagnosis, so schedule it promptly.
Without a sore, a type-specific blood (serologic) test can help, but it has real limits. The CDC does not recommend herpes blood screening for people without symptoms in most situations, because false positives are common and a result can cause more distress than it resolves. If you're trying to figure out timing for any STI check, see when to test after exposure, and if you want to arrange testing you can get tested through our partners. Don't ask for a herpes blood test "just in case" without talking through what a result would actually mean.
Treatment: episodic versus daily suppressive therapy
Three FDA-approved antivirals — acyclovir, valacyclovir, and famciclovir — control herpes CDC treatment guidelines. None cures the infection; they shorten and soften outbreaks while you take them. The two strategies work differently, and the right one depends on how often you flare and whether you're protecting a partner.
| Approach | How you take it | Best for | What it does |
|---|---|---|---|
| Episodic therapy | A short course started at the first prodrome or sore | Infrequent outbreaks | Shortens and eases each individual outbreak |
| Suppressive therapy | A pill taken every day | Frequent recurrers; protecting a partner | Cuts recurrences by 70%–80% and lowers transmission risk |
Daily suppressive therapy does more than reduce your own outbreaks. In a randomized trial of couples where one partner had HSV-2 and the other didn't, suppressive valacyclovir lowered the risk of passing the virus to the uninfected partner by about 48% Corey et al.. That's the evidence behind taking a daily pill for someone else's sake. The medications themselves are inexpensive generics, so cost is rarely the barrier.
Prevention, disclosure, and dating with herpes
Three things stack the odds in your favor: condoms, daily suppressive antivirals if you choose them, and honest disclosure. Condoms decrease but don't eliminate transmission, because they don't cover all the skin that can shed virus. Daily suppressive therapy makes passing it on less likely. And telling a partner before sex, calmly, with facts is advised, and frankly the part people dread most.
Disclosure is easier with a script. Keep it short, factual, and unapologetic. You might say: "I want to be upfront — I have genital herpes. It's common, I manage it, and I take medication that lowers the chance of passing it on. I'm happy to answer questions or send you what I've read." Pick a calm moment, not the heat of the bedroom. Most partners take it better than the worst-case scenario in your head, and the conversation often deepens trust rather than ending things.
- Disclose before sex, in a low-pressure setting, and lead with the facts rather than apology.
- Use condoms consistently and avoid skin-to-skin contact during a prodrome or visible outbreak.
- Consider daily suppressive therapy if you're in a relationship with a partner who doesn't carry the virus.
- No sore does not mean no risk, since most transmission happens with no visible outbreak.
Pregnancy and herpes
Herpes is manageable in pregnancy, but it needs a plan. Antiviral therapy late in pregnancy can reduce signs of herpes at delivery, and suppressive acyclovir started around 36 weeks lowers the need for a cesarean. A woman with recurrent lesions present at the onset of labor should have a cesarean to reduce the risk of neonatal herpes, which is serious in a newborn.

When to see a clinician
See a clinician if you have a new genital sore — get swabbed while it's fresh for the most reliable diagnosis. Book a visit if outbreaks are frequent or painful enough to disrupt your life, so you can discuss daily suppressive therapy. Reach out if you're pregnant and have a herpes history, planning a pregnancy, or starting a relationship with a partner who doesn't carry the virus and want a transmission-reduction plan. And if a first outbreak comes with high fever, severe pain, trouble urinating, or symptoms spreading beyond the genitals, get seen promptly.
