Do I have genital herpes?
Genital herpes (HSV) is very common, often causes few or no symptoms, and isn't included in most standard STI panels. Answer a few questions about your symptoms and risk factors to see how concerned to be, when a test is reliable, and where to get tested. This is a guide, not a diagnosis.

About genital herpes
What is genital herpes?
Worried you might have genital herpes? You're far from alone, and it's a calmer situation than its reputation suggests. Herpes is one of the most common STIs there is — roughly 1 in 6 Americans aged 14–49 carry it — yet most have never been diagnosed, because the symptoms are often so mild they're mistaken for a pimple, an ingrown hair or a bit of chafing. Feeling fine, or never noticing a sore, is genuinely the norm here.
There's no cure — the virus stays in the body for life — but for most healthy adults it's manageable rather than dangerous, and antiviral medicines keep outbreaks short and infrequent. Worth knowing: herpes usually isn't part of a standard STI panel, so a clean check-up doesn't mean you've been tested for it. The most accurate test is a swab of an active sore; a blood test can show past exposure when there's no sore. This check just weighs your answers to show how concerned to be.

Screening guidance
Who should get tested for genital herpes?
Because genital herpes is often silent, the CDC recommends routine screening for the groups most likely to have it — not just people with symptoms.
-
1
You have a genital, anal or oral sore right now
Get it swabbed promptly — a swab of an active sore is the most accurate test and can identify the type. Don't wait for it to heal.
-
2
A partner has told you they have herpes
A type-specific blood test can show whether you already carry the same type, and counseling helps you both weigh the real risks.
-
3
You're pregnant and you or a partner has herpes
Tell your prenatal provider so antivirals and a delivery plan can protect the newborn.
-
4
You're considering a blood test without symptoms
The CDC doesn't recommend routine herpes screening for people with no symptoms and no affected partner — blood tests can give false positives, so it's worth talking it through with a clinician first.
Timing
When a genital herpes test is reliable
If you have a sore right now, get it swabbed today — that's the most accurate test, and sensitivity drops as the sore heals, so don't wait. For a blood (antibody) test taken after a possible exposure with no current sore, antibodies can take about 4–6 weeks — and up to 12 weeks — to show up, so testing too soon can read falsely negative; wait at least 12 weeks for the most reliable result. Note: avoid IgM herpes tests, which the CDC advises against because they're unreliable.
Your genital herpes testing window
After a possible exposure, a genital herpes test becomes reliable around 4–6 weeks (antibody); a sore can be swabbed sooner later.
Before day 28 a test can miss it · from day 28 it's reliable · re-test after day 42 if you tested early.

Guidance only — confirm timing with a clinician. A negative result before the conclusive date may need a repeat test.
U.S. data
Genital Herpes in the United States
Genital herpes is more common in women than men and disproportionately affects Black women — approximately 48% carry HSV-2 antibodies compared to around 11% of white women, a disparity driven by structural inequities in healthcare access and partner network effects rather than individual behavior. HSV-1, traditionally an oral virus, now causes a significant and growing share of new genital herpes cases, especially in younger adults through oral sex. Globally, the WHO estimates 500 million people live with genital herpes.

Good to Know
Genital herpes (HSV) questions
Common questions about genital herpes (hsv) and genital herpes (hsv) testing, answered.
What does a herpes outbreak feel like?
A first outbreak can bring tingling or itching, then small painful blisters or sores on the genitals, anus, or mouth, often with fever, body aches, and swollen glands. Later outbreaks are usually milder and shorter, and many people's symptoms are so mild they're mistaken for something else.
Can you have herpes with no symptoms?
Yes — most people with genital herpes have no or very mild symptoms and don't know they carry it. It can still be passed to partners, even between outbreaks.
Is herpes included in a standard STD test?
Usually not. Most standard STD panels don't include herpes, so a 'clean' panel doesn't mean you've been tested for it. Herpes is best confirmed by swabbing an active sore; blood tests exist but aren't recommended for people without symptoms.
How soon after exposure can I test?
If you have a sore, it can be swabbed right away — that's the most accurate test. Blood (antibody) tests can take about 4–6 weeks, and up to 12 weeks, to turn positive after a new infection.
Is genital herpes dangerous?
For most healthy adults it's uncomfortable but not dangerous, and antivirals control it. The main risks are during pregnancy (it can be passed to a newborn) and for people with weakened immune systems — both need medical advice.
Trust & transparency
How this assessment works
-
Grounded in public-health guidance
The questions — and how heavily each answer counts — follow the risk factors and symptoms the CDC and WHO describe for Herpes.
-
A risk guide, not a diagnosis
Your answers produce a risk level — how concerned to be — and flag anything that needs urgent care. Only a lab test can confirm or rule out an infection.
