Human Papillomavirus (HPV) Explained: What You Need to Know

Human Papillomavirus (HPV) is the most common sexually transmitted infection (STI) globally. While many people are familiar with HPV, there are still many misconceptions. There are over 200 types of HPV, some of which can cause genital warts, while others can lead to various cancers. Most HPV infections are asymptomatic and clear on their own, but persistent infections with high-risk types are a significant concern. Our goal at WIH Hospital is to provide clear, actionable information to help you manage your health.

⌵ Understanding the Virus: How HPV Spreads & Who Is at Risk


How is HPV spread?

HPV is primarily spread through skin-to-skin contact, typically during vaginal, anal, or oral sex. It’s important to know that the virus can spread even when there are no visible warts or symptoms, making awareness and prevention vital.

Am I at risk for HPV?

Anyone sexually active can get HPV. Risk factors include:

  1. Having multiple sexual partners.
  2. Having unprotected sex.
  3. A weakened immune system.
  4. Engaging in anal sex, regardless of gender.

Recognizing the Signs: How Do I Know If I Have HPV?

Many people with HPV don’t experience any symptoms and may not know they are infected. When symptoms do appear, they depend on the type of HPV:

Genital Warts: These are caused by low-risk HPV types (most commonly HPV 6 and 11). They can appear as single or multiple bumps that may be flat, raised, or cauliflower-shaped. While typically painless, they can sometimes itch, burn, or bleed.

Cervical, Anal, or Other Cancers: High-risk HPV types (most commonly HPV 16 and 18) can cause cellular changes that may lead to cancer over time. These precancerous changes often have no symptoms in their early stages, which is why regular screening is so crucial. Symptoms of advanced cancer may include abnormal bleeding, pain, or changes in bowel habits.

⌵ The Critical Link Between HPV and Anal Health


Anal sex is a risk factor for HPV-related diseases for people of all genders. HPV can lead to:

Anal warts

Abnormal cell growth in the anal canal

Precancerous changes (known as AIN 1–3)

Anal cancer if left untreated

Early detection through screening is the most effective way to prevent these serious outcomes.

⌵ Prevention is Key: Vaccination & Other Measures


The most effective ways to reduce your risk of HPV are:

Vaccination: The HPV vaccine is a safe and highly effective way to prevent infection from the most common high-risk HPV types and those that cause genital warts. The Gardasil 9 vaccine, available at WIH Hospital, is recommended for all genders aged 9 to 45. It is especially important for those who engage in anal sex and for LGBTQ+ individuals and couples.

Condom Use: While condoms can reduce the risk of HPV transmission, they may not offer complete protection as the virus can infect areas not covered.

Limiting Sexual Partners: Reducing the number of sexual partners can lower your risk of exposure to HPV.

⌵ Testing & Diagnosis: Should I Get Tested for HPV?


HPV testing is often integrated into routine health screenings.

Cervical Screening: HPV testing is typically done in conjunction with a Pap smear to check for abnormal cells.

Anal Screening: Anal Pap smears are recommended for individuals at higher risk of anal cancer, such as gay and bisexual men, and people living with HIV.

If screening reveals abnormalities, the lesions are graded from AIN 1 to AIN 3. An AIN 3 diagnosis indicates the highest risk of developing into anal cancer, requiring close monitoring and treatment.

⌵ Advanced Treatment & Long-Term Management at WIH Hospital


There is no cure for the HPV virus itself, but the conditions it causes, such as genital warts and abnormal cell changes, can be effectively treated.

Our Treatment Services:

  1. High-Resolution Anoscopy (HRA): Our advanced diagnostic procedure includes RCI and Acetic Acid staining for precise visual examination, with or without a colposcope.
  2. Electrocautery: We use this method under local anesthesia or sedation to precisely remove genital warts or abnormal lesions.
  3. Other Treatments: Depending on the condition, warts may also be removed via topical medications, cryotherapy (freezing), surgical excision, or laser therapy. For abnormal cell changes, more severe cases may require procedures like LEEP (Loop Electrosurgical Excision Procedure).

Follow-Up Plan: A key part of our care is a customized follow-up plan to monitor for any recurrence.

  • AIN 1: Follow-up every 6–12 months
  • AIN 2: Follow-up every 6 months
  • AIN 3: Requires close monitoring

Can I get HPV again after treatment?

Yes, treatment addresses the symptoms, but it does not eliminate the virus from your body. This means you can experience a recurrence of warts or abnormal cell changes. You can also get infected with new types of HPV if exposed, which is why prevention remains a lifelong priority.

FAQ

HPV, or Human Papillomavirus, is a very common sexually transmitted infection. There are over 200 types, some of which can cause genital warts, while others can lead to various types of cancer.

Yes. While cervical cancer screening (Pap smears) is well-known, anal Pap smears and High-Resolution Anoscopy (HRA) are also crucial for individuals at higher risk of anal cancer, such as gay and bisexual men and people living with HIV.

AIN stands for Anal Intraepithelial Neoplasia. It refers to abnormal cell changes in the anal canal caused by HPV. Lesions are graded from AIN 1 to AIN 3, with AIN 3 having the highest risk of developing into anal cancer.
