The short answer: herpes causes painful blisters or sores that come and go, while HPV usually causes painless bumps (genital warts) or nothing at all. Herpes is a lifelong viral infection managed with antivirals; HPV is the most common STI, often clears on its own, and its high-risk types can cause cancer. A swab or exam tells them apart.

What each one is
Genital herpes
Genital herpes is caused by two related viruses: herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) CDC, About Herpes. Once you're infected, the virus stays in your nerve cells for life and can reactivate periodically. Most people have no symptoms or symptoms so mild they miss them, so most never know they carry it and the majority of HSV-2 infections go undiagnosed.
HPV & genital warts
Human papillomavirus is the most common STI CDC, About HPV. There are many types. The low-risk types cause genital warts, which are small, painless bumps. The high-risk types cause no symptoms but can, over years, drive cellular changes that lead to cancer. Most HPV infections are asymptomatic, and the immune system clears many of them without treatment. For the full picture on warts, see our guide to hpv & genital warts.
Symptoms compared
The single most useful distinction is pain versus no pain. Herpes lesions hurt; wart bumps generally don't.
A herpes first outbreak tends to be the worst. It starts as small blisters that break open into painful, raw sores, which take a week or more to heal. The first episode often comes with flu-like symptoms like fever, body aches, and swollen glands, because your body is meeting the virus for the first time. Sores show up on or around the genitals, the rectum, or the mouth. Later outbreaks are shorter and milder, and many people feel a warning prodrome (tingling, itching, or burning in the same spot) a day or so before sores appear.
Genital warts look different. They usually appear as a single small bump or a cluster of bumps in the genital area. They can be flat or raised, smooth or cauliflower-textured, and they're typically painless, with no blistering, no breaking open, and no flu symptoms. High-risk HPV, the kind linked to cancer, causes no bumps or symptoms at all, so screening is the only way to catch it.
How to tell them apart
One caveat: you often can't tell these apart by looking or feeling CDC Tx Guidelines. Early herpes can look bump-like before it blisters, and a wart can be mistaken for a healing sore. The discriminating features that actually help:
- Pain and the way it changes: herpes lesions are painful, blister first, then ulcerate and crust over before healing; warts stay as stable, painless bumps that don't ulcerate.
- Timeline: herpes comes in episodes that flare and resolve, then recur in the same area; warts persist or slowly grow until treated.
- Systemic symptoms: a first herpes outbreak can bring fever and swollen lymph nodes, and warts never do this.
- Texture: warts are firm, often cauliflower-like growths; herpes is a fluid-filled blister that becomes an open sore.
The overlap is real enough that you need a test, not a self-exam, to settle it.
HPV vs herpes at a glance
| Feature | Genital herpes | HPV / genital warts |
|---|---|---|
| Cause | HSV-1 or HSV-2 | Human papillomavirus |
| What you see | Blisters → painful open sores | Painless bumps; or nothing |
| Pain | Yes, often significant | Usually none |
| Course | Flares and recurs in the same spot | Persists/grows until treated |
| Systemic symptoms | Fever, aches with first outbreak | None |
| Cancer link | No | Yes — high-risk types |
| Cure | No; antivirals control it | No cure for virus; warts treatable; often clears on its own |
| Vaccine | None | Yes (HPV vaccine) |
Testing
For herpes, the best test when you have a lesion is a swab of the sore for type-specific virologic testing, either a NAAT (nucleic acid amplification test) or culture CDC, Herpes Testing. Swab-based tests work best and tell you whether it's HSV-1 or HSV-2. The sore has to be present and unhealed for the swab to catch the virus, so timing matters.
For HPV, testing is different and more limited. There's no routine HPV test for men, adolescents, or women under age 30 CDC, Pink Book; HPV screening is done through cervical screening in eligible women. Genital warts are usually diagnosed by a clinician simply looking at them.
What testing involves depends on which infection is suspected: a urine sample, a self-collected swab, or a quick visual exam. You can get tested at low or no cost through health departments, Planned Parenthood, and Title X clinics. If you're testing because of a specific encounter, read up on when to test after exposure so you don't test too early and get false reassurance.
Treatment compared
Neither virus has a cure, but both are manageable. For herpes, three FDA-approved oral antivirals (acyclovir, valacyclovir, and famciclovir) shorten and control outbreaks but don't clear the virus. They can be taken episodically at the first sign of an outbreak or daily as suppressive therapy. Suppressive therapy does more than reduce your own flares: in a randomized trial of serodiscordant couples, daily valacyclovir lowered the risk of passing HSV-2 to a partner by about 48% Corey et al., NEJM, so some people take it for a partner's sake. If you're weighing your options, our overview of alternative herpes treatments explains what's supported and what isn't.
For genital warts, several patient-applied creams and solutions are options: imiquimod 3.75% or 5% cream, podofilox 0.5% solution or gel, and sinecatechins 15% ointment (sinecatechins aren't recommended for people who are immunocompromised or HIV-positive) CDC, Anogenital Warts. Clinic-based removal methods also exist. Treating warts removes the visible growths but doesn't necessarily eliminate the virus.
The biggest difference is prevention: there's an effective HPV vaccine and no herpes vaccine. Given at the recommended ages, the HPV vaccine can prevent more than 90% of HPV-caused cancers, and Gardasil 9 is about 98% effective against the precancers caused by HPV 16 and 18 American Cancer Society. HPV causes virtually all cervical cancer, over 90% of anal cancers, and about 70% of throat (oropharyngeal) cancers, and oropharyngeal cancer has now overtaken cervical cancer as the most common HPV-related cancer in the US NCI.
Can you have more than one at once?
Yes. HPV and herpes are caused by completely different viruses, and having one offers no protection against the other. Because both are extremely common and both frequently cause no symptoms, plenty of people carry both without knowing. A bump-vs-sore distinction can't rule out a second infection; only testing and screening can. It's one more reason a self-diagnosis isn't reliable.
When to see a clinician
See a clinician if you notice any new genital bump, sore, blister, or unusual growth, especially while you can still see it, since a herpes swab works best on an active lesion. Also seek care if you have painful sores with fever or swollen glands (a possible first herpes outbreak), bumps that grow or multiply, or any new lesion after a new partner. Keep up with cervical screening if you're eligible, regardless of symptoms, because high-risk HPV is silent.
