Most women with HPV have no symptoms at all, which is why the infection is so easy to miss. About 85% of people will get an HPV at some point in their lifetime, and the vast majority of those infections cause no visible signs. The only reliable way to know if you have HPV is through screening tests, since your body rarely gives you obvious clues.
Why HPV Usually Has No Symptoms
The majority of HPV infections are asymptomatic. Your immune system quietly fights the virus in the background, and about 80% to 90% of infections clear on their own within two years. During that time, you can carry the virus and pass it to a partner without ever knowing you’re infected.
This is what makes HPV different from many other infections. There’s no fever, no fatigue, no discharge that signals something is wrong. The virus can persist for years in a small number of people, gradually causing cellular changes on the cervix that only show up on a screening test. That’s why routine screening matters so much: it catches what your body can’t tell you about.
Visible Signs That Can Appear
When HPV does produce symptoms, it’s usually the low-risk strains (not the cancer-causing ones) that make themselves known through genital warts. These can appear on the vulva, inside the vagina, around the anus, or on the cervix. They look like small, skin-colored bumps that sometimes cluster together in a cauliflower-like shape. Some are raised, others are flat, and many are so small you can’t see them with the naked eye.
Genital warts can cause itching or discomfort in the area, and some women notice bleeding during sex. They may go away on their own, stay the same, or grow in size or number. Importantly, the strains that cause visible warts are almost always different from the high-risk strains linked to cervical cancer. So the absence of warts doesn’t mean you’re in the clear, and the presence of warts doesn’t mean you’re at higher cancer risk.
How HPV Testing Works
There are two main screening tools, and they feel identical from your perspective. Both involve a speculum exam where a provider collects cells from your cervix. The difference is what happens in the lab.
- HPV test: The collected cells are checked for the presence of high-risk HPV strains. This tells you whether you’re carrying a virus that could eventually cause cervical changes.
- Pap test (Pap smear): The cells are examined under a microscope for abnormal changes. This tells you whether the virus has already started affecting your cervical cells.
No special preparation is needed for an HPV test. If you’re getting a Pap test, avoid intercourse, douching, and vaginal medicines for two days before your appointment so the results are accurate.
There is no approved blood test for HPV. And currently, there’s no recommended HPV test for the throat, vulva, or other sites outside the cervix. Screening only detects cervical HPV infections.
When and How Often to Get Screened
Current guidelines recommend cervical cancer screening for women ages 21 to 65 who are at average risk. The specific approach depends on your age:
- Ages 21 to 29: A Pap test every three years. HPV co-testing is not recommended in this age group because HPV infections are so common in younger women and almost always resolve on their own.
- Ages 30 to 65: A primary HPV test every five years is preferred. Alternatively, you can get a combined HPV and Pap test (co-testing) every five years, or a Pap test alone every three years if HPV testing isn’t available.
Women at average risk should not be screened more frequently than every three years. More frequent testing leads to unnecessary follow-up procedures without improving outcomes.
Self-Collection HPV Tests
The FDA has approved self-collected HPV tests that can be done at home, which is a newer option for women who find clinic-based screening uncomfortable or inaccessible. A provider still needs to order the test and supply the collection device. Availability is limited right now, but these tests are expected to become more widely accessible over time. Self-collection is currently an option for women ages 30 to 65 at average risk.
What a Positive HPV Result Means
A positive HPV test does not mean you have cancer. It means high-risk HPV was detected in your cervical cells. What happens next depends on several factors: your current test results, your previous screening history, any past treatments for cervical cell changes, and your age.
Based on your overall risk level, your provider may recommend one of three paths. You might simply return for a repeat HPV or co-test in one to three years. You might need a colposcopy, which is a closer examination of the cervix using a magnifying instrument. During a colposcopy, a vinegar solution is applied to the cervix to highlight abnormal areas, and a small tissue sample (biopsy) is typically taken. Or, if significant precancerous changes are found, you might need treatment to remove those cells.
Two strains in particular, HPV 16 and HPV 18, cause about 70% of cervical cancers worldwide. When a high-risk infection persists for years instead of clearing, it can slowly change cervical cells into precancerous tissue. If that tissue isn’t found and removed, it can eventually develop into cancer. This process typically takes many years, which is why regular screening is so effective at catching problems early.
HPV Vaccination After Exposure
If you’ve already tested positive for HPV, vaccination can still be beneficial. A study published in Scientific Reports tracked 320 women who tested positive for HPV and had never been vaccinated. Among the 250 who chose to get vaccinated, 72.4% completely cleared their HPV infection during the follow-up period, compared to 45.7% of those who didn’t get vaccinated. The effect was even stronger for the specific strains covered by the nine-strain vaccine.
Vaccination doesn’t treat an active infection the way an antibiotic treats bacteria. But it appears to support the immune response and may help the body clear the virus more effectively. It also protects against strains you haven’t been exposed to yet. The vaccine is approved for people through age 45, so even if you weren’t vaccinated as a teenager, it’s worth discussing with your provider.
How HPV Spreads
HPV is transmitted through skin-to-skin contact during sexual activity, including vaginal, anal, and oral sex. Condoms reduce the risk but don’t eliminate it, because the virus can live on skin that a condom doesn’t cover. You can contract HPV from a partner who has no symptoms and no idea they’re carrying the virus. There’s no way to know when you were infected or who transmitted it, and having HPV says nothing about the number of partners you’ve had. A single sexual contact is enough.
