01 · Overview
The short version
A person can have herpes without obvious sores
Genital herpes can cause painful blisters and sores, but some people have only mild symptoms or none at all. That is why testing matters when symptoms are new or when a partner has been diagnosed.
It spreads through direct sexual contact and skin-to-skin contact
Herpes can spread during vaginal, anal, or oral sex, and sometimes through other sexual skin contact. Condoms lower the risk, but they do not remove it completely.
Other conditions can look similar
Yeast, friction, dermatitis, shaving irritation, and other STIs can all cause sores, bumps, or burning. A swab from a sore or a blood test may be used depending on the timing and symptoms.
Medicine can help even though the virus stays in the body
There is no cure that removes herpes from the body, but antiviral medicines can shorten outbreaks, ease symptoms, and lower the risk of passing the virus to someone else.
02 · Care guidance
When to get help
Emergency help
- Get emergency care now if a newborn may have been exposed during delivery.
- Get emergency care now if you have eye pain or vision changes and think herpes may be involved.
- Get emergency care now if severe weakness, confusion, or trouble drinking fluids develops.
Get advice promptly
- Contact a clinician soon if you have new genital blisters or sores, burning with urination, frequent recurrences, symptoms after a new sexual partner, or a sore that is not healing as expected.
- Seek prompt care if you are pregnant, have a weakened immune system, or think your symptoms could be herpes, syphilis, or another STI.
If symptoms are mild and you are otherwise well, arrange a non-urgent visit for testing, treatment discussion, and guidance on partner protection and outbreak care.
03 · Genital Herpes
What genital herpes means in plain terms
Genital herpes is a lifelong viral infection that may cause repeated outbreaks, often becoming less frequent over time.
Genital herpes is caused by herpes simplex virus. HSV-2 is the usual cause, but HSV-1 can also infect the genital area. Once the virus gets into the body, it stays there for life.
The first episode can feel very different from later ones. Some people get painful blisters that break open and become sores. Others notice only mild irritation or nothing they would connect to an STI. That is one reason the diagnosis is sometimes missed until testing is done.
Outbreaks often happen more often in the first year and then become less frequent. The symptoms may also become milder over time, but the virus does not go away.
- Blisters may appear near the genitals, buttocks, thighs, or anal area.
- Symptoms can be absent or easy to miss.
- The infection can still be passed on even between outbreaks.

How it spreads, and why condoms do not fully block it
Herpes spreads mainly through direct sexual contact, even when sores are not visible.
Genital herpes can spread during vaginal, anal, or oral sex. It can also spread through contact with the mouth, genitals, or anus when the virus is active on the skin. A person may not know they have it, which is why transmission can happen before anyone notices sores.
Condoms lower the risk, but they do not fully prevent herpes because the virus can be on skin that the condom does not cover. Polyurethane condoms are an option if latex is a problem.
The safest way to avoid infection is not to have vaginal, anal, or oral sex. For many people, that is not the choice they want to make, so the practical question becomes how to reduce risk as much as possible.
- Transmission can happen with or without obvious sores.
- Skin-to-skin exposure matters, not just fluid exposure.
- Avoid sexual contact during active outbreaks when possible.

Signs that fit herpes, and signs that could be something else
Painful blisters, sores, itching, or burning are common, but the same pattern can come from other problems.
A first outbreak may cause clusters of blisters that open and become painful sores. Some people also notice itching, tingling, burning with urination, or tender glands. Sores may show up where the virus entered the body, but they can also appear on nearby skin such as the buttocks or thighs.
Later outbreaks are often shorter and less severe than the first one. Even so, a new genital sore should not be ignored. Herpes is only one possible explanation. Yeast, friction, dermatitis, shaving irritation, syphilis, and other STIs can look similar.
If you are trying to decide whether to wait it out, the pattern matters. Mild redness after shaving may improve quickly. A sore that blisters, breaks open, or keeps recurring deserves testing.
- Tingling or burning can come before sores appear.
- Pain with urination may happen if urine touches open sores.
- A new sore is not proof of herpes by itself.

What testing can show, and why timing matters
Testing may involve a swab of a sore or a blood test, depending on whether symptoms are present.
If you have a fresh sore, getting seen early can matter because there is more to sample. A clinician may swab the lesion to look for herpes. If the sore has already healed, a swab may not help much.
When there are no visible sores, blood testing may sometimes be used. That can help in some situations, but it does not always show when infection was acquired or explain old symptoms by itself. A negative result also does not always settle the question if the timing was early.
Testing is useful because many genital symptoms overlap. If the cause is syphilis or another STI, the treatment and partner guidance may be different. Clear testing avoids treating the wrong problem and may lower the chance of passing infection to others.
- Try to be seen early in an outbreak if possible.
- Tell the clinician if you are pregnant or have a weak immune system.
- Bring up any recent sexual contact or partner diagnosis.

What treatment can and cannot do
Antiviral medicines can help outbreaks heal sooner and may reduce future outbreaks and transmission risk.
There is no cure that removes herpes from the body, but antiviral medicines are commonly used. They can shorten an outbreak, reduce discomfort, and in some people lower the chance of passing the virus to someone else.
Treatment may be started when symptoms begin, or it may be prescribed as ongoing prevention for people who have frequent outbreaks or want to reduce spread risk. Which approach fits depends on your health, symptom pattern, and goals.
If symptoms are severe, if outbreaks are happening often, or if a partner is pregnant, treatment planning becomes more important. It is also worth asking about medication timing if you are worried that your outbreak is not improving as expected.
- Start treatment early when possible.
- Do not share prescription antiviral medicine with other people.
- Treatment choice depends on your health and outbreak pattern.

Sex, partners, pregnancy, and staying safer day to day
Herpes can be managed long term, but pregnancy and newborn exposure need special care.
If you have a known diagnosis, it helps to tell sexual partners before sex. That gives both people a chance to think about protection, testing, and whether sex should wait during symptoms. Condoms and antiviral medicine may lower risk, but they do not fully prevent transmission.
Avoid sex when sores are open or when warning symptoms such as tingling or burning suggest an outbreak. That is when the virus is more likely to spread. If you are not sure whether irritation is herpes, it is safer to wait until you have been checked.
Pregnancy changes the stakes. Genital herpes can sometimes be passed to a baby during childbirth, and newborn infection can be serious. If you are pregnant, trying to become pregnant, or think a newborn may have been exposed, the timing of care matters more than self-treatment.
- Tell partners about a known diagnosis before sex.
- Avoid sex during open sores or warning symptoms.
- Pregnancy and newborn exposure need prompt medical attention.
09 · FAQ
Questions people ask
Should I have sex during an outbreak?
It is safer to wait. Open sores and warning symptoms such as tingling or burning mean the virus is more likely to spread. Even if you feel well enough, sex during that time can expose a partner. If you are unsure whether a sore is herpes or something else, avoid sex until you are evaluated.
Can I take over-the-counter medicine for pain?
Some people use common pain relievers for discomfort, but read the label carefully and make sure they are safe for you. If you have kidney disease, ulcers, are pregnant, or take blood thinners, ask a clinician or pharmacist before using them. Gentle rinsing with lukewarm water and loose clothing can also help reduce irritation.
Is genital herpes dangerous in pregnancy?
It can be, especially if the infection is new late in pregnancy or if sores are present near delivery. Because newborn herpes can be serious, pregnancy calls for prompt obstetric guidance rather than waiting for the outbreak to pass on its own. Tell your obstetric clinician about any history of herpes or possible exposure.
When should I get tested after possible exposure?
If you develop sores, pain, or tingling, get checked as soon as possible. If you have no symptoms but are worried about exposure, a clinician can help decide whether testing now or later makes sense. The timing matters because some tests are more useful once symptoms appear or after enough time has passed for blood tests to turn positive.
Can a sore that is not healing be herpes?
It could be, but a sore that lingers can also be syphilis, irritation, or another infection. A non-healing sore deserves a visit because the cause may need different treatment. If you have a weak immune system, are pregnant, or notice worsening pain or discharge, get seen sooner rather than later.
Can oral sex spread genital herpes?
Yes. HSV can spread through oral sex, and HSV-1 can cause genital infection as well as cold sores around the mouth. That means a partner’s mouth or genitals can be part of the exposure, even if the person has no obvious symptoms at the time.
