HPV (Human Papilloma Virus)

HPV often causes no symptoms, and many people carry the virus without knowing they are infected. When symptoms do occur, they may include:aHPV often causes no symptoms, and many people carry the virus without knowing they are infected. When symptoms do occur, they may include:

• Genital warts, appearing as small, fleshy bumps or skin growths around the genital or anal area
• Raised or clustered lesions, sometimes with a cauliflower-like appearance
• Itching, irritation, or discomfort in the affected area (warts are often painless)

High-risk types of HPV typically do not cause visible symptoms but may lead to abnormal cell changes over time. These changes are usually detected through routine cervical screening rather than physical symptoms.

Yes, it is very common to have HPV without any noticeable symptoms. Most people with HPV do not develop visible signs, so the infection often goes undetected. Even without symptoms, HPV can still be transmitted to sexual partners.

Low-risk types may cause genital warts, while high-risk types are usually asymptomatic and are often only identified through cervical screening or other clinical assessments. Because HPV frequently has no symptoms, regular screening remains an important part of sexual health.

Most HPV infections clear naturally without causing harm. However, persistent infection with high-risk HPV types can lead to abnormal cell changes (dysplasia), which may progress to cancer over time if not identified and managed.

This includes cervical cancer, as well as cancers of the anus, penis, vulva, vagina, and some head and neck sites. Low-risk types can cause genital warts, which are benign but may be recurrent and distressing for some individuals.

If HPV causes symptoms, they may appear weeks to months after exposure. However, in many cases, visible signs such as genital warts can take several months to develop.

High-risk HPV types usually do not cause symptoms and may remain undetected for years, only being identified through cervical screening after causing gradual cell changes. Many people with HPV never develop symptoms at all.

HPV is caused by a group of viruses that are spread through direct skin-to-skin contact, most commonly during sexual activity. This includes vaginal, anal, and oral sex, as well as close genital contact and sharing sex toys. The virus enters through microscopic breaks in the skin or mucous membranes and can be transmitted even when no symptoms are present. Because HPV is very common, most sexually active people will be exposed to it at some point.

Several factors can increase the likelihood of acquiring HPV, including:

• Having multiple sexual partners
• Having a partner with multiple previous partners
• Becoming sexually active at a younger age
• Having a weakened immune system (e.g. due to illness or medication)
• Smoking, which may impair the body’s ability to clear the virus

HPV can affect anyone who is sexually active, even those with a single lifetime partner.

The most effective way to reduce the risk of HPV is vaccination, alongside safer sex practices and regular screening. The HPV vaccine protects against the types most commonly associated with genital warts and HPV-related cancers.

Condoms and dental dams reduce the risk of transmission but do not provide complete protection, as HPV spreads through skin-to-skin contact. For individuals with a cervix, regular cervical screening is important for detecting high-risk HPV and early cell changes.

Yes, it is still possible to get HPV even if you use a condom. Although condoms reduce the risk of transmission, they do not provide full protection against HPV because the virus can spread through contact with skin not covered by the condom, such as the surrounding genital area. However, condom use remains important as it lowers the risk of HPV and helps protect against many other sexually transmitted infections.

The risk of getting HPV from kissing is considered very low. HPV is most commonly spread through intimate skin-to-skin contact during vaginal, anal, or oral sex. While some HPV types can infect the mouth and throat, transmission is more strongly associated with oral sex than with kissing. Kissing alone is not considered a common route of transmission.

It is very unlikely to get HPV from sharing personal items. HPV is primarily spread through direct skin-to-skin contact during sexual activity. Although the virus may survive briefly on surfaces, transmission via objects such as towels or razors is considered extremely uncommon. Avoiding sharing personal hygiene items is a sensible precaution.

No, HPV is not transmitted through blood transfusions. It is not a blood-borne virus, as it infects skin and mucosal tissues rather than circulating in the bloodstream. Transmission occurs through direct skin-to-skin contact, most commonly during sexual activity.

HPV is diagnosed in different ways depending on whether it is causing visible symptoms or being detected through screening.

If genital warts or visible skin changes are present, diagnosis is usually clinical, based on examination.

High-risk HPV is most commonly detected through cervical screening, where a sample of cells from the cervix is tested for HPV and any associated cell changes.

There is no routine test to check for all HPV types in people without symptoms. In selected cases, HPV testing (such as PCR-based swabs) may be used, depending on clinical indication and anatomical site.

Several approaches may be used depending on the clinical situation:

• Clinical examination to diagnose genital warts based on appearance
• Cervical screening, which tests for high-risk HPV in individuals with a cervix
• HPV DNA (PCR) tests from cervical, anal, or other sites in selected cases

The most appropriate approach depends on symptoms, anatomy, and the reason for testing. Routine HPV testing outside established screening programmes is not always indicated.

A correct diagnosis depends on the type of symptoms, the location and appearance of any lesions, and the clinical experience of the healthcare professional.

Providing a clear history—such as when symptoms appeared and how they have changed—can support accurate assessment. Many benign skin conditions can resemble HPV, so professional evaluation is important.

Yes, several conditions can be mistaken for HPV, particularly when genital warts are suspected. Common examples include skin tags, pearly penile papules, Fordyce spots, molluscum contagiosum, ingrown hairs, cysts, and moles. Many of these conditions are harmless and not sexually transmitted, but they can appear similar to genital warts. Because of this, a professional examination is recommended if you notice any unusual lumps, bumps, or skin changes.

In some cases, additional investigations may be required. These can include biopsy, where a small tissue sample is analysed, or targeted HPV PCR testing.

These are typically reserved for cases where the diagnosis is uncertain, lesions are atypical, or there is concern about abnormal cell changes.

HPV can sometimes be diagnosed from examination alone when genital warts are present, as they are often recognisable clinically.

However, many HPV infections—particularly high-risk types—do not cause visible symptoms. In these cases, screening or targeted testing is required, as examination alone cannot exclude infection.

No, HPV cannot be reliably diagnosed at home. While you may notice lumps, bumps, or skin changes, many other conditions can appear similar.

High-risk HPV usually causes no visible symptoms. Although self-sampling HPV kits exist (primarily for cervical screening), results require appropriate interpretation and follow-up within a clinical setting.

The long-term prognosis for most people with HPV is very good. In the majority of cases, the immune system clears or suppresses the virus within 1–2 years without causing health problems, and many people never develop symptoms.

If HPV persists, outcomes depend on the type involved. Low-risk types may cause genital warts, which can recur but are not cancerous. High-risk types can lead to abnormal cell changes (dysplasia), which, if persistent and untreated, may increase the risk of certain cancers over time.

Regular screening allows early detection and management of these changes, significantly reducing the risk of progression.

No, treatment does not provide immunity to HPV. There are many different HPV types, and prior infection with one type does not protect against others.

It is also possible for the same HPV type to persist at low levels in the body and become active again, rather than representing a true new infection. Treatments for HPV-related conditions, such as genital warts, remove visible lesions but do not eradicate the virus itself.

There is no guaranteed way to prevent HPV from reappearing, but certain measures can reduce risk and support immune control:

• HPV vaccination (to protect against additional high-risk and wart-causing types)
• Avoiding smoking, which is associated with persistence of HPV
• Maintaining overall health to support immune function
• Using condoms to reduce the risk of transmission and re-exposure

HPV may persist at low levels in the body even after symptoms resolve, and in some cases may become detectable again.

There is no legal requirement to disclose HPV to a partner. HPV is very common, and most sexually active people will be exposed at some point, often without knowing.

However, some people choose to discuss this with partners, particularly if they have visible genital warts or recent abnormal screening results. Open communication can support shared decision-making around sexual health.

Although it is not possible to eliminate the risk of transmission completely, the following can reduce the likelihood:

• Using condoms or dental dams
• Avoiding sexual contact when visible genital warts are present
• HPV vaccination if eligible
• Engaging with recommended screening programmes

Because HPV spreads through skin-to-skin contact, these measures reduce but do not eliminate risk.

HPV can be transmitted to a baby during childbirth, but this is very uncommon. In most cases, even if exposure occurs, the baby clears the virus without developing any health problems.

HPV in pregnancy does not usually affect fetal development and is not associated with miscarriage or preterm birth. In rare cases, transmission may lead to recurrent respiratory papillomatosis, a condition causing wart-like growths in the airway.

The presence of HPV alone is not an indication for caesarean section.

HPV does not usually cause complications during pregnancy. Hormonal and immune changes may cause genital warts to increase in size or number.

In rare cases, very large warts may cause discomfort or, occasionally, interfere with vaginal delivery. Most individuals with HPV have normal pregnancies without HPV-related complications.

HPV is very common during pregnancy, just as it is among the general adult population. Many pregnant individuals may already have HPV without knowing, as the virus often causes no symptoms. Pregnancy does not increase your likelihood of getting HPV, although hormonal changes may make existing symptoms, such as genital warts, more noticeable.

Management depends on symptoms. If treatment for genital warts is required, physical methods such as cryotherapy may be used during pregnancy.

Hyfrecation or surgical removal can be considered in selected cases but is not routinely required. Many topical treatments (e.g. podophyllotoxin, imiquimod) are generally avoided during pregnancy.

If symptoms are mild, treatment is often deferred until after delivery. Decisions should be individualised to balance symptom control and safety.

Most pregnant individuals with HPV do not need additional precautions beyond routine antenatal care.

If you have genital warts or a history of abnormal cervical screening, inform your healthcare provider so appropriate monitoring can be arranged. Over-the-counter wart treatments should be avoided unless advised by a clinician.

HPV does not usually affect postpartum recovery. The virus is not transmitted through breast milk, so breastfeeding is considered safe.

If treatment is needed after birth, suitable options can be selected that are compatible with breastfeeding.
