HPV Infection

Human papillomavirus (HPV) infection is one of the most common sexually transmitted infections (STIs) worldwide. It's so common that nearly all sexually active people will get it at some point in their lives if they don't get the HPV vaccine. There are many different types of HPV, and some are more high-risk than others. While most HPV infections clear up on their own without causing any health problems, certain types can lead to genital warts and various cancers. This comprehensive guide provides detailed information about HPV infection, including its causes, symptoms, diagnosis, treatment, and prevention strategies.

HPV is a viral infection that commonly causes skin or mucous membrane growths (warts). There are over 200 different types of HPV, categorized as either low-risk or high-risk.

• Low-risk HPV types can cause warts on the hands, feet, or genitals.
• High-risk HPV types can cause various cancers, including cervical, anal, oropharyngeal (throat), penile, vaginal, and vulvar cancer.

HPV is primarily spread through sexual contact, including vaginal, anal, and oral sex. It can also be spread through close skin-to-skin contact during sexual activity.

• Worldwide: HPV is incredibly common globally. According to a study, an estimated 80% of sexually active women and men will be infected with at least one type of HPV by 45 years of age.
• India: Cervical cancer, primarily caused by HPV, is a significant public health problem in India. It is the second most common cancer among women in India. Cervical cancer (87.6%) and oropharyngeal cancer (63.2%) are two common HPV-related cancers among females and males, respectively. 

As mentioned earlier, there are numerous types of HPV. Some of the most well-known include:

• HPV 6 and 11: These are low-risk types that cause genital warts.
• HPV 16 and 18: These are high-risk types responsible for the majority of HPV-related cancers.
• Other high-risk types: These include 31, 33, 35, 45, 52, and 58, which can also cause cancers.

HPV infection is caused by the human papillomavirus. It spreads through direct contact with infected skin or mucous membranes. While sexual contact is the most common mode of transmission, it's important to understand that HPV can be spread even without penetration.

Sexual contact

This includes vaginal, anal, and oral sex. The virus can be present on the genitals, as well as in the mouth and throat.

Skin-to-skin contact

HPV can spread through close skin-to-skin contact in the genital area, even without penetration. This means that condoms, while helpful in reducing the risk, cannot completely eliminate the chance of transmission.

Mother-to-child transmission

Although rare, HPV can be passed from mother to baby during childbirth. This can result in the baby developing a condition called recurrent respiratory papillomatosis (RRP), which involves the growth of warts in the respiratory tract.

Shared objects

While less common, it's possible to contract certain types of HPV through sharing objects like razors or towels with an infected person. This is more likely to lead to common warts rather than genital warts.

It's important to remember that HPV is very common, and most sexually active people will contract it at some point in their lives. Having HPV does not necessarily mean that someone has been unfaithful in a relationship, as the virus can remain dormant for years.

Most people with HPV infection don't experience any symptoms. The virus can remain dormant in the body for years. However, when HPV symptoms do appear, they can include:

• Genital warts: These are small, flesh-coloured or grey bumps in the genital area. They can be single or multiple and may be raised, flat, or cauliflower-shaped.
• Common warts: These are rough, raised bumps that usually appear on the hands and fingers.
• Plantar warts: These are hard, grainy growths that appear on the soles of the feet.
• Flat warts: These are small, flat-topped warts that can appear anywhere on the body.
• Precancerous changes: In some cases, HPV can cause changes to the cells of the cervix, which can lead to cancer if left untreated. These changes usually don't cause any symptoms and are detected through cervical screening.

• Visual examination: Genital warts can often be diagnosed through a visual examination by a healthcare professional.
• Pap test: This screening test is used to detect abnormal cells in the cervix that may be caused by HPV.
• HPV test: This test can detect the presence of high-risk HPV types in cervical cells. It is often done in conjunction with a Pap test.
• Colposcopy: If abnormal cells are found during a Pap test, a colposcopy may be performed to examine the cervix more closely.
• Biopsy: A small tissue sample may be taken during a colposcopy for further examination under a microscope.

There is no specific cure for HPV infection itself, but the body's immune system often clears the virus on its own within a couple of years. However, HPV treatments are available to address the health problems that the virus can cause:

• Genital warts: Various treatments can be used to remove genital warts. These include: 
  • Topical medications: Creams or solutions applied directly to the warts, such as imiquimod, podofilox, or trichloroacetic acid.
  • Cryotherapy: Freezing the warts with liquid nitrogen.
  • Electrocautery: Burning the warts with an electric current.
  • Laser therapy: Using a laser to destroy the warts.   
  • Surgical removal: Cutting away the warts in a minor surgical procedure.
• Precancerous changes: If HPV infection leads to precancerous changes in the cervix, treatments aim to remove the abnormal cells and prevent them from developing into cancer. These may include: 
  • Loop electrosurgical excision procedure (LEEP): Using a thin, wire loop heated by an electrical current to remove abnormal tissue.
  • Conization: Removing a cone-shaped piece of tissue from the cervix.
  • Cryotherapy: Freezing the abnormal cells.
• Cancer: If HPV infection leads to cancer, treatment options will depend on the type and stage of cancer and may include: 
  • Surgery: To remove the cancerous tissue.
  • Radiation therapy: Using high-energy rays to kill cancer cells.
  • Chemotherapy: Using drugs to kill cancer cells.
  • Targeted therapy: Using drugs that target specific molecules involved in cancer growth.

It's important to discuss the best treatment options with your healthcare provider, as the choice will depend on the specific condition and individual circumstances.

While there's no cure for HPV, some alternative therapies may help boost the immune system and support the body's natural ability to fight the virus. However, it's crucial to remember that these therapies are not a substitute for conventional medical treatment and should be used in conjunction with advice from a healthcare professional.

Dietary changes

Eating a healthy diet rich in fruits, vegetables, and whole grains can support immune function. Some studies suggest that certain nutrients, such as folate, vitamin C, and beta-carotene, may be particularly beneficial.

Herbal remedies

Some herbs, such as echinacea, astragalus, and garlic, are believed to have immune-boosting and antiviral properties. However, more research is needed to confirm their effectiveness against HPV.

Stress management techniques

Chronic stress can weaken the immune system, making it harder for the body to fight off infections. Managing stress through practices like yoga, meditation, deep breathing exercises, or spending time in nature may be helpful.

Mind-body therapies

Practices like mindfulness, guided imagery, and tai chi can help reduce stress and promote overall well-being, which may indirectly support the immune system.

It's important to consult with a healthcare professional before trying any alternative therapies, as they may not be suitable for everyone, especially for those with underlying health conditions or taking medications. They can help you assess the potential benefits and risks and ensure that these therapies are used safely and effectively.

Several factors can increase the risk of HPV infection:

• Multiple sexual partners: Having multiple sexual partners increases the likelihood of exposure to HPV.
• Early sexual activity: Starting sexual activity at a young age increases the risk of HPV infection.
• Weakened immune system: People with weakened immune systems are more susceptible to HPV infection and its complications.
• Smoking: Smoking can increase the risk of persistent HPV infection and the development of HPV-related cancers.

Most HPV infections clear up on their own without causing any problems. However, persistent infection with high-risk HPV types can lead to serious complications, including:

• Cervical cancer: This is the most common cancer caused by HPV.
• Other cancers: HPV can also cause anal, oropharyngeal, penile, vaginal, and vulvar cancer.
• Genital warts: These are noncancerous growths that can be uncomfortable and unsightly.
• Recurrent respiratory papillomatosis (RRP): This rare condition is caused by HPV types 6 and 11 and involves the growth of warts in the respiratory tract.

1. Follow your doctor's recommendations. Attend all follow-up appointments and adhere to any prescribed treatments.

2. Practice safe sex. Use condoms to reduce the risk of transmitting HPV to others.

3. Boost your immune system by maintaining a healthy lifestyle with a balanced diet, regular exercise, and stress management techniques.

4. Attend regular cervical screening. This is crucial for early detection and treatment of any precancerous changes.

5. Seek support if you are feeling anxious or overwhelmed. Talk to your doctor, a counsellor, or a support group.

HPV is only a women's issue.

HPV can affect both men and women and can cause various health problems in both sexes.

HPV always causes symptoms.

Most people with HPV infection don't experience any symptoms.

HPV means you have cancer.

While high-risk HPV types can cause cancer, most infections clear up on their own without causing any problems.

You can't get HPV if you're in a monogamous relationship.

Even if you are in a monogamous relationship, you or your partner may have been exposed to HPV in the past.

• If you notice any unusual growths or warts in the genital area.
• If you experience any abnormal bleeding or discharge.
• If you have any concerns about HPV infection or your sexual health.
• For routine cervical screening (Pap tests and HPV tests).

• What type of HPV do I have?
• What are the risks and complications associated with this type of HPV?
• What treatment options are available?
• How often should I be screened for cervical cancer?
• What can I do to reduce my risk of transmitting HPV to others?

• Be understanding and non-judgemental: HPV infection is common and nothing to be ashamed of.
• Offer emotional support: Listen to their concerns and offer reassurance.
• Encourage them to seek medical advice: Help them find a healthcare professional they feel comfortable with.
• Educate yourself about HPV: Learning about the virus can help you understand what they are going through.
• Respect their privacy: Don't share their personal information with others.

HPV infection is a widespread viral infection that can cause a range of health problems, from genital warts to cancer. While there is no cure for HPV, most infections clear up on their own. Vaccination, safe sex practices, and regular cervical screening are crucial for preventing HPV-related complications.
