HPV Infection: Symptoms, Risks, and Treatment Options

Introduction

Human papillomavirus (HPV) is one of the most prevalent sexually transmitted infections (STIs) globally, affecting millions of people each year. Many individuals remain unaware they are infected. HPV is associated with a range of health issues, including genital warts and certain cancers, such as cervical, anal, and throat cancers. Although the virus was first identified in the early 20th century, it wasn’t until the 1980s that researchers established a link between HPV and cancer. Since then, significant strides have been made in understanding the virus and developing vaccines to prevent infection.

This article offers a detailed overview of HPV infection, addressing risk factors, symptoms, diagnostic tests, treatments, and home care options. Whether you are concerned about your risk of contracting HPV or seeking information following a diagnosis, this guide will help you better understand the condition and how to manage it.

What is Human Papillomavirus (HPV) Infection?

Human papillomavirus (HPV) infection is a widespread viral condition that can lead to health problems such as genital warts and cancer. This article will explore the risk factors, symptoms, diagnostic tests, treatments, and home care strategies for managing HPV infection.

Description of Human Papillomavirus (HPV) Infection

HPV refers to a group of over 200 related viruses, some of which are transmitted through direct skin-to-skin contact, including sexual contact. HPV is classified into two main categories: low-risk and high-risk types. Low-risk types can cause genital warts, while high-risk types are linked to cancers, including cervical, anal, and oropharyngeal (throat) cancers. Not everyone infected with HPV will develop symptoms, and in many cases, the immune system clears the infection naturally.

HPV infection progresses in stages. Initially, the virus enters the body through small cuts or abrasions in the skin. In most cases, the immune system clears the infection within two years. However, in some individuals, the virus persists, leading to warts or precancerous lesions. If left untreated, these lesions can eventually progress to cancer.

HPV is extremely common. According to the Centers for Disease Control and Prevention (CDC), nearly 80 million Americans are currently infected with HPV, and about 14 million people, including teenagers, become newly infected each year. Most sexually active individuals will contract HPV at some point, but many will remain unaware due to the absence of symptoms.

Risk Factors for Developing Human Papillomavirus (HPV) Infection

Lifestyle Risk Factors

Certain lifestyle choices can increase the risk of contracting HPV. Engaging in unprotected sexual activity, particularly with multiple partners, is a significant risk factor. HPV is primarily transmitted through vaginal, anal, or oral sex. While condoms or dental dams can reduce the risk, they do not provide complete protection. Smoking also increases the likelihood of persistent HPV infection by weakening the immune system. Additionally, alcohol and drug use may impair judgment, leading to risky sexual behaviors that heighten exposure to HPV.

Medical Risk Factors

A weakened immune system, whether due to HIV infection, organ transplantation, or certain medications, makes it more difficult for the body to clear an HPV infection. Women with a history of abnormal Pap smears or cervical dysplasia are also at higher risk for HPV-related complications. Furthermore, individuals with other sexually transmitted infections (STIs), such as chlamydia or herpes, may be more susceptible to contracting HPV, as these infections can cause inflammation and skin damage, making it easier for the virus to enter the body.

Genetic and Age-Related Risk Factors

While HPV can affect individuals of any age, younger people, particularly those in their late teens and early 20s, are at higher risk due to increased sexual activity. However, older individuals are not immune, and the risk of developing HPV-related cancers increases with age, especially in those over 50. Although there is no definitive genetic predisposition to HPV infection, some studies suggest that certain genetic factors may influence how the body responds to the virus, potentially affecting the likelihood of clearing the infection or developing complications.

Clinical Manifestations of HPV Infection

Genital Warts

Genital warts are one of the most common clinical manifestations of HPV infection, affecting about 1% of sexually active adults in the United States. These warts are caused by low-risk HPV types, particularly HPV types 6 and 11. Genital warts appear as small, flesh-colored or gray growths in the genital area, including the vulva, vagina, cervix, penis, scrotum, or anus. They may be raised or flat, single or multiple, and sometimes form a cauliflower-like cluster. While generally painless, genital warts can cause discomfort, itching, or bleeding, especially during intercourse. Treatment options include topical medications, cryotherapy, or surgical removal, though the virus may persist even after the warts are removed.

Common Warts

Common warts, or verruca vulgaris, typically occur on the hands and fingers and are caused by HPV types 1, 2, and 4. They affect about 7-10% of the general population. Common warts are small, rough, raised bumps that can be flesh-colored, white, or gray. While usually painless, they can be bothersome due to their appearance or location. HPV infects the top layer of the skin, causing rapid cell growth, which leads to the formation of these warts. Although common warts often resolve on their own, treatments like salicylic acid, cryotherapy, or laser therapy may be used to remove them.

Plantar Warts

Plantar warts develop on the soles of the feet and are caused by HPV types 1, 2, and 4. These warts are relatively common, affecting around 10% of the population at some point. Plantar warts can be painful, especially when located on weight-bearing areas of the foot, such as the heel or ball. They often appear as small, hard, grainy growths with a rough surface and may have black dots in the center, which are clotted blood vessels. The pressure from walking or standing can cause plantar warts to grow inward, making them harder to treat. Treatment options include over-the-counter salicylic acid, cryotherapy, or minor surgical procedures.

Flat Warts

Flat warts, or verruca plana, are caused by HPV types 3, 10, and 28. They are less common, accounting for about 4% of all warts. Flat warts are small, smooth, and slightly raised lesions, usually flesh-colored or light brown. They tend to appear in clusters on the face, neck, hands, or legs. Flat warts are more common in children and young adults and can spread through direct contact or by scratching. Although generally painless, flat warts can be cosmetically concerning. Treatment options include topical retinoids, cryotherapy, or laser therapy.

Itching

Itching is a frequent symptom of HPV-related warts, particularly genital warts. Itching occurs in about 20-30% of individuals with genital warts. The virus irritates the skin or mucous membranes, causing an itchy sensation. Itching can range from mild to severe and may worsen with friction, such as during sexual activity or from tight clothing. Scratching the affected area can lead to further irritation or secondary infections. Treating the underlying warts often alleviates itching, and over-the-counter antihistamines or topical creams may provide temporary relief.

Burning Sensation

A burning sensation is another symptom that can occur with HPV-related warts, especially in the genital area. This symptom is reported in about 10-15% of individuals with genital warts. The burning sensation may result from skin or mucous membrane irritation caused by the warts. It can worsen with friction, such as during sexual intercourse or when wearing tight clothing. In some cases, the burning sensation may be accompanied by itching or discomfort. Treating the warts, along with using soothing creams or ointments, can help reduce the burning sensation.

Abnormal Pap Test

An abnormal Pap test result is one of the most common indicators of HPV infection, particularly in women. Approximately 5-10% of women who undergo routine Pap testing will have abnormal results, which may indicate HPV-related changes in cervical cells. HPV can cause cervical cells to undergo abnormal changes, known as dysplasia, detectable through a Pap smear. These changes can range from mild to severe and may progress to cervical cancer if untreated. An abnormal Pap test result typically leads to further diagnostic testing, such as an HPV DNA test or colposcopy, to determine the cause of the abnormality.

Lesions

HPV-related lesions can appear on the skin or mucous membranes, particularly in the genital area. These lesions may be flat, raised, or cauliflower-like, depending on the HPV type. Lesions are more common in individuals with genital warts and can cause discomfort, itching, or bleeding. In some cases, HPV-related lesions can progress to precancerous or cancerous changes, especially in the cervix, anus, or throat. Early detection and treatment of HPV-related lesions are crucial to prevent complications.

Discomfort During Intercourse

Discomfort during intercourse, or dyspareunia, can occur in individuals with genital warts or other HPV-related lesions. This symptom is reported in about 15-20% of individuals with genital warts. The presence of warts or lesions in the genital area can cause friction and irritation during sexual activity, leading to pain or discomfort. In some cases, the discomfort may be accompanied by itching or a burning sensation. Treating the underlying warts or lesions can help alleviate this symptom, and using lubricants during intercourse may provide temporary relief.

Bleeding

Bleeding is a less common symptom of HPV infection, occurring in about 5-10% of individuals with genital warts or lesions. Bleeding may occur if the warts or lesions are irritated or injured, such as during sexual activity or when using tampons. In some cases, bleeding may be a sign of more serious HPV-related changes, such as cervical dysplasia or cancer. If you experience unexplained bleeding, seek medical evaluation to determine the cause and receive appropriate treatment.

Health Conditions with Similar Symptoms to Human Papillomavirus (HPV) Infection

Genital Herpes

Genital herpes is a sexually transmitted infection (STI) caused by the herpes simplex virus (HSV). It results in painful sores or blisters around the genital or anal area. HSV-1 typically causes cold sores around the mouth, while HSV-2 is more commonly associated with genital herpes. However, both types can cause genital infections.

How to Know if You Might Have Genital Herpes vs. Human Papillomavirus (HPV) Infection

Both genital herpes and HPV can cause lesions in the genital area, but they differ in appearance. Genital herpes usually presents with painful, fluid-filled blisters or ulcers that may burst and scab over, often accompanied by itching, burning, or tingling. In contrast, HPV-related genital warts are typically painless, flesh-colored, and have a cauliflower-like appearance.

Genital herpes outbreaks tend to recur, often triggered by stress or illness, while HPV-related warts may persist or resolve without recurring. Additionally, genital herpes may cause flu-like symptoms such as fever, body aches, and swollen lymph nodes, which are not typical of HPV infections.

To distinguish between the two, healthcare providers may perform a viral culture or PCR test on a sample from herpes sores to confirm HSV infection. Blood tests can also detect HSV antibodies. HPV is diagnosed through visual inspection of warts, a Pap smear, or an HPV DNA test. If HSV is confirmed, it indicates genital herpes rather than HPV.

Syphilis

Syphilis is a bacterial infection caused by Treponema pallidum. It progresses through stages, starting with a painless sore (chancre) at the infection site, followed by a rash, and, if untreated, serious complications affecting the heart, brain, and other organs. Syphilis is primarily spread through sexual contact.

How to Know if You Might Have Syphilis vs. Human Papillomavirus (HPV) Infection

In its early stages, syphilis can cause a painless sore or ulcer that may resemble an HPV wart. However, syphilis sores (chancres) are typically firm, round, and painless, while HPV warts are soft and may have a rough surface. Syphilis sores usually appear on the genitals, anus, or mouth and heal on their own within a few weeks, even without treatment.

As syphilis progresses, it can cause a rash that may cover the entire body, including the palms and soles, which is not a feature of HPV. Additionally, syphilis can cause fever, swollen lymph nodes, and fatigue, which are not typical of HPV.

To diagnose syphilis, healthcare providers use blood tests like the rapid plasma reagin (RPR) or venereal disease research laboratory (VDRL) test to detect antibodies. A positive result indicates syphilis rather than HPV.

Molluscum Contagiosum

Molluscum contagiosum is a viral skin infection caused by the molluscum contagiosum virus (MCV). It results in small, firm, raised bumps on the skin that may be flesh-colored, white, or pink. These bumps often have a central dimple and can appear anywhere on the body, including the genital area.

How to Know if You Might Have Molluscum Contagiosum vs. Human Papillomavirus (HPV) Infection

Both molluscum contagiosum and HPV can cause bumps in the genital area, but their appearance differs. Molluscum contagiosum lesions are smooth, dome-shaped, and have a central dimple, while HPV warts are rough, cauliflower-like, and lack a central indentation.

Molluscum contagiosum bumps are usually painless, though they may become itchy or irritated. HPV warts are also generally painless but can cause discomfort depending on their location. Unlike HPV, molluscum contagiosum does not cause warts inside the vagina or anus.

Healthcare providers typically diagnose molluscum contagiosum through visual examination of the lesions. In some cases, a biopsy may be performed. HPV is diagnosed through visual inspection, a Pap smear, or an HPV DNA test. If the lesions have a central dimple, molluscum contagiosum is more likely than HPV.

Candidiasis (Yeast Infection)

Candidiasis, commonly known as a yeast infection, is caused by an overgrowth of the fungus Candida. It can affect various parts of the body, but vaginal yeast infections are the most common. Symptoms include itching, burning, and a thick, white discharge from the vagina.

How to Know if You Might Have Candidiasis vs. Human Papillomavirus (HPV) Infection

Both candidiasis and HPV can cause itching in the genital area, but candidiasis is more likely to cause intense itching, burning, and discomfort, especially during urination or sexual intercourse. Additionally, candidiasis often produces a thick, white, cottage cheese-like vaginal discharge, which is not a symptom of HPV.

HPV warts are typically painless and do not cause discharge. If you experience itching without visible warts and have a thick discharge, candidiasis is more likely. Candidiasis can also cause redness and swelling of the vulva, which is not a feature of HPV.

To diagnose candidiasis, healthcare providers may take a sample of vaginal discharge and examine it under a microscope to look for yeast cells. HPV is diagnosed through visual inspection of warts, a Pap smear, or an HPV DNA test. If yeast cells are present, candidiasis is the likely diagnosis.

Bacterial Vaginosis (BV)

Bacterial vaginosis (BV) is a common vaginal infection caused by an imbalance of bacteria in the vagina. It often results in a thin, grayish-white discharge with a strong, fishy odor. BV is not considered a sexually transmitted infection, but it is more common in sexually active women.

How to Know if You Might Have Bacterial Vaginosis vs. Human Papillomavirus (HPV) Infection

Both BV and HPV can cause changes in the vaginal area, but the symptoms are quite different. BV typically causes a thin, grayish discharge with a strong, fishy odor, which is not a symptom of HPV. HPV warts do not cause discharge or odor.

BV can also cause itching or irritation in the vaginal area, but this is usually mild compared to the itching caused by HPV warts. Additionally, BV does not cause visible warts or lesions, while HPV does.

To diagnose BV, healthcare providers may take a sample of vaginal discharge and test its pH or examine it under a microscope for signs of bacterial imbalance. HPV is diagnosed through visual inspection of warts, a Pap smear, or an HPV DNA test. If the discharge has a high pH and contains clue cells (bacteria-coated vaginal cells), BV is the likely diagnosis.

Herpes Simplex Virus (HSV)

The herpes simplex virus (HSV) causes infections in various parts of the body, most commonly the mouth (oral herpes) and genitals (genital herpes). HSV-1 typically causes cold sores around the mouth, while HSV-2 is more commonly associated with genital herpes. Both types can cause painful sores or blisters.

How to Know if You Might Have Herpes Simplex Virus vs. Human Papillomavirus (HPV) Infection

Both HSV and HPV can cause lesions in the genital area, but the nature of these lesions differs. HSV causes painful, fluid-filled blisters or ulcers, while HPV causes painless, flesh-colored warts. HSV sores may burst and scab over, while HPV warts remain intact and do not scab.

HSV infections often cause flu-like symptoms such as fever, body aches, and swollen lymph nodes, which are not typical of HPV. Additionally, HSV outbreaks tend to recur, while HPV warts may persist or resolve without recurring.

To diagnose HSV, healthcare providers may perform a viral culture or PCR test on a sample from the sores. Blood tests can also detect antibodies to HSV. HPV is diagnosed through visual inspection of warts, a Pap smear, or an HPV DNA test. If the test confirms HSV, it indicates herpes rather than HPV.

Treatment Options for HPV Infection

Medications

Imiquimod

Imiquimod is a topical cream that stimulates the immune system to fight off the HPV virus. It is primarily used to treat external genital warts caused by HPV.

Imiquimod is applied directly to the affected area, usually three times a week for up to 16 weeks. It is often prescribed for patients with small to moderate-sized warts. This medication is typically used as a first-line treatment for genital warts.

Patients can expect to see a reduction in wart size and number within a few weeks of starting treatment. Complete clearance of warts may take several months.

Podofilox

Podofilox is a topical solution or gel that works by destroying the tissue of genital warts. It is a self-applied treatment that targets external warts caused by HPV.

Podofilox is applied twice daily for three days, followed by four days of no treatment. This cycle can be repeated for up to four weeks. It is typically used for smaller warts and is a first-line treatment option.

Patients using Podofilox can expect to see warts shrink or disappear within a few weeks. However, it may cause mild skin irritation at the application site.

Sinecatechins

Sinecatechins is an ointment derived from green tea extract. It is used to treat external genital and perianal warts caused by HPV.

This medication is applied three times daily for up to 16 weeks. It is often prescribed for patients who prefer a plant-based treatment option. Sinecatechins is a first-line treatment for genital warts.

Most patients experience a gradual reduction in wart size and number over several weeks. Complete clearance may take a few months.

Trichloroacetic Acid (TCA)

Trichloroacetic acid is a chemical solution that destroys warts by breaking down the proteins in the wart tissue. It is applied by a healthcare provider.

TCA is typically used for small warts and is applied once a week until the warts are gone. It is often used when other topical treatments are not effective or for patients who prefer in-office treatments.

Patients can expect warts to gradually disappear after a few treatments. Some mild discomfort or irritation may occur at the application site.

Cryotherapy

Cryotherapy involves freezing warts with liquid nitrogen, causing the wart tissue to die and eventually fall off. This procedure is performed by a healthcare provider.

Cryotherapy is often used for external genital warts and is typically performed every 1-2 weeks until the warts are gone. It is a common first-line treatment for patients with multiple or larger warts.

Patients can expect warts to fall off within a few days to weeks after treatment. Some mild pain or blistering may occur at the treatment site.

Laser Therapy

Laser therapy uses focused light to destroy wart tissue. It is a more advanced treatment option for HPV-related warts.

This procedure is typically reserved for larger or more stubborn warts that have not responded to other treatments. It is performed in a healthcare setting under local anesthesia.

Patients can expect immediate destruction of the wart tissue, with healing occurring over the following weeks. Some scarring may occur.

Surgical Excision

Surgical excision involves cutting away warts using a scalpel or other surgical tools. This procedure is performed by a healthcare provider.

Excision is usually reserved for large or persistent warts that have not responded to other treatments. It is performed under local anesthesia in a healthcare setting.

Patients can expect immediate removal of the warts, with healing taking place over several weeks. There may be some scarring at the excision site.

Interferon

Interferon is an antiviral medication that boosts the immune system to fight off HPV. It is injected directly into the wart tissue.

This treatment is typically reserved for patients with persistent or recurrent warts that have not responded to other therapies. It is usually administered in a healthcare setting.

Patients can expect a gradual reduction in wart size and number over several weeks. However, interferon is not commonly used due to its potential side effects and the availability of other treatments.

5-Fluorouracil (5-FU)

5-Fluorouracil is a topical chemotherapy cream that destroys rapidly growing cells, such as those found in warts. It is used to treat HPV-related warts.

This medication is applied directly to the warts, usually once daily for several weeks. It is typically reserved for more resistant warts that have not responded to other treatments.

Patients can expect a gradual reduction in wart size and number over several weeks. Some skin irritation may occur at the application site.
