Key facts

HPV at a glance.

The essentials, in plain English - what HPV is, how it behaves and how UK medicine keeps it in check.

  • What it is

    A family of more than 200 related DNA viruses that infect skin and mucous membranes, spread by skin-to-skin and sexual contact.

  • How common

    Extremely common - most sexually active adults acquire at least one HPV type in their lifetime, usually without symptoms.

  • Most infections clear

    Around 80 to 90 per cent of infections are cleared by the immune system within one to two years without treatment.

  • High-risk types

    HPV 16, 18, 31, 33, 45, 52 and 58 can drive cervical, anal, oropharyngeal, vulval, vaginal and penile cancers.

  • Low-risk types

    HPV 6 and 11 cause the majority of anogenital warts and rare recurrent respiratory papillomatosis.

  • Prevention

    The 9-valent Gardasil vaccine and UK primary HPV cervical screening have transformed HPV-related cancer prevention.

Why this guide matters

A common virus, an uncommon amount of confusion.

HPV covers everything from a hand wart to cervical cancer. Understanding which type does what turns anxiety into a clear plan.

  • Most HPV clears without treatment

    Around 80 to 90 per cent of infections are cleared by the immune system within two years - the immune system is genuinely on your side.

  • Vaccination is transformative

    Gardasil 9 protects against nine HPV types and has already cut cervical pre-cancer rates dramatically in the vaccinated generation.

  • Screening finds problems early

    UK primary HPV cervical screening picks up high-risk infection years before cancer could develop - attend every invitation.

How the diagnosis is made

From first concern to a clear plan.

The steps a UK GP, GUM clinician or specialist will normally follow, in order - so you know what to expect and why.

  1. 01

    Assessing

    Full sexual health history

    A confidential history of exposures, partners and prior screening frames the right tests and vaccination advice.

  2. 02

    Assessing

    Genital and skin examination

    Careful inspection for anogenital warts, verrucae and common warts - often the only clinical clue that HPV is present.

  3. 03

    Assessing

    Cervical screening (women 25 to 64)

    Primary HPV testing on a liquid-based cytology sample - the UK first-line test for high-risk HPV at the cervix.

  4. 04

    Confirming

    Colposcopy for abnormal screens

    A magnified view of the cervix with acetic acid and iodine, guided biopsy if abnormalities are seen.

  5. 05

    Confirming

    Anal cytology and HRA

    High-resolution anoscopy for higher-risk groups including MSM and people living with HIV - specialist-led.

  6. 06

    Preparing

    ENT review if suspected oropharyngeal disease

    Persistent throat symptoms, a neck lump or unexplained ear pain warrant a head-and-neck cancer pathway referral.

  7. 07

    Preparing

    Counselling and partner support

    A calm, evidence-based conversation about transmission, disclosure, vaccination and follow-up - as important as any test.

Typical timeline: first visit to a clear plan within a few weeks.

Symptoms

How HPV actually shows up.

Warts, subclinical infection, cervical changes and, rarely, cancers of the cervix, anus, oropharynx, vulva, vagina or penis.

  • Anogenital warts

    Flesh-coloured, cauliflower-like papillomas around the vulva, penis, perineum or anus - usually HPV 6 or 11.

  • Common warts and verrucae

    Firm, keratotic papules on hands, fingers and soles - most often HPV 1, 2 and 4.

  • Subclinical infection

    The majority - no visible lesion at all, often detected only through routine cervical screening.

  • Cervical changes (CIN)

    Cervical intraepithelial neoplasia found on screening - graded CIN 1 to 3 depending on depth.

  • Vulval, vaginal and penile changes

    HPV-related dysplasia (VIN, VaIN, PIN) - white plaques, pigmentation or persistent itch that need biopsy.

  • Oropharyngeal disease

    Persistent sore throat, neck lump, ear pain or a hoarse voice - HPV 16 is now a leading cause of tonsil and tongue-base cancers.

  • Anal changes

    Anal warts, bleeding, itch or a mass - higher-risk in MSM and people living with HIV.

  • Red flag - persistent bleeding or lesion

    Postcoital or intermenstrual bleeding, non-healing ulcer or a persistent lump needs same-week clinical review.

Treatment

How HPV is managed in the UK.

Vaccination for prevention, topical or clinic-based treatments for warts, LLETZ for cervical changes and MDT care for cancer.

  • Gardasil 9 vaccination

    The UK primary prevention - offered to boys and girls at school age and available privately for adults. See /conditions/hpv-vaccination/.

  • Podophyllotoxin or imiquimod

    Patient-applied topical creams for external anogenital warts - two 3-day cycles or up to 16 weeks respectively.

  • Cryotherapy

    Liquid nitrogen freezing of warts in a GUM or dermatology clinic - repeated weekly until clearance. See /treatments/genital-wart-treatment/.

  • Electrocautery, laser or excision

    Specialist options for extensive, keratinised or resistant lesions - performed under local anaesthetic.

  • LLETZ or cone biopsy

    Large loop excision of the transformation zone - the standard treatment for high-grade cervical CIN. See /conditions/cervical-cancer-screening/.

  • Vulval, vaginal or penile treatment

    Imiquimod, laser, excision or specialist multidisciplinary care depending on site and grade.

  • Head-and-neck cancer pathway

    Suspected HPV-related oropharyngeal disease is managed by ENT and oncology MDTs. See /conditions/head-and-neck-cancer/.

  • Counselling and psychological support

    A specialist nurse or psychologist can help with disclosure, relationships and the anxiety a positive HPV result can bring.

Red flags

When HPV needs urgent attention.

Most HPV is managed in primary or sexual health care. These are the situations that need faster, specialist review.

  • Postcoital or intermenstrual bleeding

    Persistent unexplained bleeding in a woman with a cervix needs urgent examination and colposcopy - a two-week-wait referral if unresolved.

  • Non-healing genital ulcer

    An ulcer that does not heal within four weeks needs specialist review to exclude HPV-related cancer.

  • Neck lump or persistent sore throat

    A neck lump lasting three weeks or a persistent unilateral sore throat needs a head-and-neck two-week-wait referral.

  • Anal bleeding, pain or mass

    Any new anal lump, bleeding or persistent pain needs specialist assessment - particularly in MSM and people living with HIV.

  • Rapidly growing or pigmented warts

    Sudden change in a wart, ulceration, pigmentation or bleeding warrants biopsy to exclude squamous cell carcinoma.

  • Immunocompromise

    People living with HIV, transplant recipients and those on long-term immunosuppression need earlier, more frequent HPV surveillance.

  • Recurrent respiratory papillomatosis

    A rare condition of laryngeal papillomas causing voice change or stridor in children and adults - urgent ENT review.

  • Pregnancy with active warts

    Anogenital warts in pregnancy need obstetric and GUM co-management - podophyllotoxin and imiquimod are contraindicated.

  • Psychological distress after a positive result

    A positive HPV or abnormal screening result can be distressing - ask for counselling; it is a normal part of care.

Living with it

A common virus, handled well.

Four things make the biggest difference over time - vaccination, screening, open conversations and compassionate support.

A quiet reminder

Having HPV says nothing about you as a person.

It is one of the most common viruses in human biology. Ask for the same practical, kind care you would for any other infection.

  1. 01 Vaccinate

    Prevention is the strongest lever

    Gardasil 9 protects against nine HPV types and is now offered to boys and girls. Adult catch-up is available privately.

  2. 02 Screen

    Attend every cervical screen

    Primary HPV testing is the most effective way to prevent cervical cancer - attend from age 25 to 64 when invited.

  3. 03 Talk

    Disclosure is manageable

    HPV is so common that most partners have already been exposed - a calm, factual conversation is usually enough.

  4. 04 Support

    It is not a moral failing

    HPV can be acquired at any point in a sexual life, sometimes decades earlier. Ask for psychological support if you need it.

Frequently asked

Everything we get asked about HPV.

Quick answers on transmission, clearance, vaccination, screening and what an abnormal result means.

  • What is HPV?

    Human papillomavirus is a family of more than 200 related DNA viruses that infect skin and mucous membranes. Most are harmless, some cause warts, and a smaller group of high-risk types can drive cervical, anal, oropharyngeal, vulval, vaginal and penile cancers over years to decades.

  • How is HPV spread?

    HPV is spread mainly by skin-to-skin and sexual contact - vaginal, anal and oral. Condoms reduce but do not eliminate transmission because the virus lives on skin the condom does not cover. Common warts on hands and verrucae on feet spread by direct contact and shared surfaces.

  • Will my HPV clear on its own?

    For most people, yes. Around 80 to 90 per cent of HPV infections are cleared by the immune system within one to two years without any treatment. Persistent infection with a high-risk type over many years is what raises cancer risk, which is why cervical screening focuses on detecting persistence.

  • Should adults have the HPV vaccine?

    Adults who missed the school programme can benefit from Gardasil 9 - especially before or in early sexual life, and in groups at higher risk including MSM up to age 45. The vaccine is available privately in the UK and is the strongest single step you can take to prevent HPV-related cancers.

  • What does an abnormal cervical screening result mean?

    It usually means high-risk HPV has been detected and, if cell changes are also seen, colposcopy is offered. Colposcopy is a magnified look at the cervix that takes about 15 minutes; if needed, a small biopsy or LLETZ treatment can be arranged. Most abnormalities never become cancer if followed up properly.

  • Do genital warts mean I have a high-risk HPV type?

    Not usually. Anogenital warts are almost always caused by low-risk HPV 6 and 11, which do not cause cancer. It is possible to carry both low-risk and high-risk types, so routine cervical screening remains important for anyone with a cervix regardless of a wart history.
