Human Papillomavirus Infection: Causes, Symptoms and Treatment

Human papillomavirus (HPV) is one of the most common viral infections in the world. In most cases, the body’s immune system clears the virus naturally, and it does not cause any health problems.

However, in some people, the virus does not go away and remains in the body. When HPV infection persists, it can lead to various health conditions, ranging from harmless skin or tissue growths to serious cancers. Because of these risks, HPV is a major public health concern, highlighting the importance of prevention, regular screening, and early treatment.

In this blog, we will explore what a human papillomavirus infection is and how it spreads. We will look at what symptoms look like, how medical professionals treat the condition, and prevention methods.

What Is Human Papillomavirus?

The human papillomavirus (HPV) is not a single virus but a large group of related viruses spread through skin-to-skin contact. With over 200 types, some cause common warts on the hands or feet, while others affect the genitals. The virus enters through tiny cuts in the skin and lives in the surface cells of the skin and mucous membranes. Although many infections cause no symptoms, understanding HPV is the first step toward protecting your health.

Types of Human Papillomavirus

There are many different types of human papillomavirus, and not all affect the body in the same way, which is why doctors group HPV strains into low-risk and high-risk categories to better identify potential health risks and guide prevention and treatment.

How Is HPV Related To Cervical Cancer?

The link between human papillomavirus and cervical cancer is well established, as nearly all cases of cervical cancer are caused by high-risk HPV infections. When the virus remains in the body for a long time, it enters the cells lining the cervix and alters the way they grow. Over time, these abnormal changes can develop into cancer if they are not detected and treated. This is why routine screening is so important, as it helps identify these changes early, before cancer has a chance to develop.

Who Can Be Affected by HPV?

Anyone sexually active can contract a human papillomavirus infection, as the virus does not discriminate based on gender or background. It is so common that nearly all sexually active men and women will be exposed to at least one type of HPV at some point in their lives if they are not vaccinated.

HPV in Men

Men often carry the virus without symptoms, which allows it to spread unknowingly. When signs do appear, they usually include warts on the penis, scrotum, or around the anus, and in some cases, high-risk strains can lead to cancers of the penis, anus, or throat. The risk is higher for men with weakened immune systems, making early awareness and prevention important.

HPV in Women

Anyone sexually active can get human papillomavirus, as it spreads easily through skin-to-skin contact. It is extremely common, and most people will be exposed to at least one type of HPV in their lifetime if they are not vaccinated.

Symptoms of HPV

Most people with human papillomavirus (HPV) do not show symptoms because the immune system keeps the virus under control. When signs do appear, they usually show up as warts, and their location and appearance depend on the strain involved.

Genital Warts

These appear as flat lesions or small, cauliflower-like bumps. In women, they can develop on the vulva, near the anus, on the cervix, or in the vagina. In men, they usually appear on the penis, scrotum, or around the anus. They rarely cause pain, but they may itch.

Common Warts

These are rough, raised bumps that usually appear on the hands and fingers and may become painful or bleed if injured. Because they spread through touch, they can appear in new areas. Although harmless, they can still be uncomfortable and unsightly.

Plantar Warts

These are hard, grainy growths that appear on the heels or balls of the feet and, because of their location, can cause discomfort or pain when you walk or stand.

Flat Warts

These are flat-topped and slightly raised lesions, usually darker than your natural skin colour. Which can appear anywhere but are common on the face, neck, or legs.

Causes of HPV

A human papillomavirus infection spreads through direct contact when the virus passes from one person to another and enters the skin or mucous membranes.

Skin-to-Skin Contact

The virus can spread by touching a wart on someone else or by coming into contact with contaminated surfaces, which is common for hand and foot warts. Walking barefoot in public showers or swimming pools increases the risk of developing plantar warts.

Sexual Transmission

This is the main way genital HPV spreads, as the virus passes from person to person during vaginal, anal, or oral sex and through intimate skin-to-skin contact. Penetration is not required for transmission, and although using condoms lowers the risk, it does not eliminate it because the virus can live on areas of skin that condoms do not cover.

Mother to Child Transmission

Although rare, a pregnant woman with active genital warts can pass human papillomavirus to her baby during delivery, which may lead to warts developing in the baby’s throat or voice box.

What Are The Complications Of HPV?

The most serious outcome of this virus is cancer, as high-risk strains can cause permanent damage to cells even though most infections are harmless. While cervical cancer is the most well-known result, human papillomavirus can also lead to several other types of cancer.

• Anal Cancer: The virus can cause changes in the cells of the anus, which may eventually lead to anal cancer in both men and women.
• Penile Cancer: High-risk strains can affect the skin of the penis, which may eventually lead to penile cancer.
• Throat Cancer: The virus can infect the back of the throat, including the base of the tongue and the tonsils, which can lead to oropharyngeal cancer.
• Vaginal Cancer: This is a rare type of cancer that forms in the vagina and is strongly linked to high-risk HPV infection.
• Vulvar Cancer: This cancer affects the outer surface of the female genitalia and often begins as a lump or sore that does not heal.

How Is HPV Diagnosed?

Detecting human papillomavirus early is key to preventing cancer, and doctors use specific tests to find the virus or the cell changes it causes, with the approach differing for men and women.

For Men

• Visual Inspection: A healthcare provider examines the genital area to look for warts or lesions and determine whether they are consistent with an HPV infection.
• Anal Pap Test: Doctors may use this test for men who are at higher risk, including those who have sex with men, to check for abnormal cells in the anal canal.
• HPV DNA Test for Men: This is not a standard test for the general public and is mainly used for research, though doctors may apply it in certain high-risk cases to identify the presence of the virus.

For Women

• Pap Smear (Cervical Screening Test): This is a routine procedure in which the doctor collects a sample of cells from the cervix and sends them to a lab to detect abnormal changes, and women are generally advised to begin this screening at age 21.
• HPV DNA Test: This test looks for the genetic material of the virus and identifies high-risk strains that are more likely to cause cancer. It is often done alongside a Pap smear for women over the age of 30.

How is HPV Treated?

Medical science has not yet found a cure for the virus itself, so treatment focuses on managing symptoms and removing abnormal cells, with doctors aiming to clear visible warts and treat precancerous changes in the cervix.

• Cryosurgery: This treatment involves freezing the warts or abnormal cells with liquid nitrogen, where the extreme cold destroys the tissue.
• Loop Electrosurgical. In this procedure, doctors use a thin wire loop charged with electricity to cut away abnormal tissue from the cervix.
• Electrocautery: This method uses an electrical current to burn off warts and is effective for removing specific growths.
• Laser Therapy: This method uses an intense beam of light to destroy warts or abnormal cells and is often chosen when other treatments are difficult to apply.
• Cold Knife Cone Biopsy: In this procedure, a doctor uses a scalpel to remove a cone-shaped piece of tissue from the cervix, which removes the abnormal cells.
• Prescription Cream: Doctors may prescribe medicated creams that you apply directly to the warts at home, helping the immune system fight the virus.
• Trichloroacetic Acid: A healthcare provider applies this chemical solution to the warts, where it burns off the growth.

Can HPV Be Prevented?

It is difficult to completely avoid exposure to human papillomavirus because of how common the infection is; however, you can take steps to significantly reduce your risk.

• HPV Vaccines: This is the most effective form of protection, as the vaccine guards against the strains responsible for most cancers and warts.
• Practice Safe Sex: Using contraceptives consistently lowers the risk of transmission and helps protect both you and your partner.
• Get Regular Screenings: Women should follow the recommended schedule for Pap smears, as early detection helps prevent cancer.
• Maintain Good Hygiene: Keep skin clean and dry. Avoid walking barefoot in public areas to prevent plantar warts.
• Avoid Smoking: Smoking weakens the immune system. People who smoke are less able to clear the virus from their bodies.
• Educate and Communicate: Talk to sexual partners about sexual health. Honest communication helps both parties stay safe.
