Genital herpes is a common, manageable viral infection — not a sign of poor hygiene or a single partner's "fault" — and once you have it, the virus stays in your body permanently, with recurrences usually becoming milder and less frequent over time. It's caused by the herpes simplex virus (HSV-1 or HSV-2), transmitted through skin-to-skin contact during vaginal, anal, or oral sex, including from a partner who has no visible symptoms at the time.
How it's actually transmitted
- Skin-to-skin contact, not only through visible sores — the virus can shed from the skin even when nothing is visibly wrong, which is why it spreads even between outbreaks.
- Either HSV type, from either site — HSV-1 (traditionally linked to cold sores) and HSV-2 (traditionally linked to genital herpes) can each infect either the mouth or the genitals, usually through oral sex.
- Not through toilet seats, towels, or casual contact — the virus doesn't survive well outside the body, so transmission is specifically from direct skin contact with an infected area.
The first episode vs. a recurrence
| First episode | Recurrence | |
|---|---|---|
| Severity | Often the most intense episode | Usually milder |
| Duration | Can last 2–4 weeks | Often shorter, days to about a week |
| Symptoms | Blisters/sores, pain, sometimes fever and swollen lymph nodes | Usually just local blisters or sores, without systemic symptoms |
| Warning signs | Not always present | A tingling, itching, or burning sensation often precedes visible sores by a day or so |
Recurrences generally become less frequent and less severe over the first year or two as your body's immune response to the virus matures.
What actually triggers a recurrence
Common triggers include stress, illness or fever, menstruation, friction during sex, and a weakened immune system. Triggers vary between individuals, and tracking your own pattern over a few recurrences can help you anticipate and sometimes shorten an episode by starting treatment at the very first tingling sensation, rather than waiting for a visible sore.
How it's managed
- Antiviral medication (such as acyclovir, valacyclovir, or famciclovir) shortens episodes and reduces viral shedding — started as early as possible in an episode works best.
- Suppressive daily therapy is an option for people with frequent recurrences, and also meaningfully reduces the chance of passing the virus to a partner.
- Local comfort measures — loose clothing, keeping the area clean and dry, and avoiding friction — help with discomfort during an active episode.
- Telling a partner is a conversation worth having proactively, since consistent condom use and avoiding contact during an active outbreak both reduce (though don't eliminate) transmission risk.
A herpes diagnosis often feels much bigger in the first week than it actually turns out to be in practice — it's a manageable, common condition that most people learn to recognise and handle with increasing confidence over time.
Frequently asked
Does genital herpes affect my ability to get pregnant?
No, herpes itself doesn't affect fertility. The main consideration in pregnancy is managing any active outbreak around the time of delivery, since a first-episode infection very close to labour carries a small risk to the newborn — something your obstetrician will specifically plan around if you have a history of herpes.
Can I still have a normal vaginal delivery if I have herpes?
In most cases, yes — a C-section is specifically recommended only if you have visible sores or prodromal symptoms right around the time of labour, not simply because of a herpes diagnosis in general.
How do I know if it's herpes and not something else, like a yeast infection or an ingrown hair?
Herpes sores typically appear as small, fluid-filled blisters that break open into shallow, painful ulcers, often with a preceding tingling sensation. If you're not sure, a swab test during an active sore is the most reliable way to confirm it rather than guessing from appearance alone.
Will my recurrences ever stop completely?
For many people they become infrequent enough to barely notice over the years, though the virus itself remains in the body permanently. Suppressive therapy is an option if recurrences stay frequent or bothersome.
Can I pass it to a partner even when I have no symptoms?
Yes — this is called asymptomatic shedding, and it's one of the main reasons herpes spreads even when both partners believe there's no active outbreak. Consistent condom use and, for frequent recurrences, suppressive antiviral therapy both reduce this risk.
