What Is Human Papillomavirus (HPV)? Symptoms, Risks, and Prevention
Human Papillomavirus (HPV) is one of the most common sexually transmitted infections (STIs) globally. In fact, most sexually active people will contract at least one type of HPV in their lifetime. While many cases clear up on their own, certain strains can lead to serious health problems such as genital warts and various cancers.
This guide explains everything you need to know about HPV—including how it spreads, symptoms to watch for, and ways to prevent infection—especially through vaccination and routine screening.
What Is HPV?
HPV refers to a group of over 100 related viruses. Some types of HPV affect the genital area, while others can affect the mouth, throat, or even skin. Most strains are harmless and resolve without treatment. However, a few high-risk types can cause long-term complications such as:
- Cervical cancer
- Anal cancer
- Throat (oropharyngeal) cancer
- Genital warts
HPV is transmitted primarily through skin-to-skin contact during vaginal, anal, or oral sex. Condoms reduce the risk but don’t provide full protection, as HPV can spread through areas not covered by a condom.
Types of HPV: High-Risk vs Low-Risk
HPV is broadly classified into:
- Low-risk HPV: Includes types like HPV 6 and 11, which may cause genital warts but are not linked to cancer.
- High-risk HPV: Includes types like HPV 16 and 18, known to cause various cancers, especially cervical cancer.
Knowing the type of HPV you have helps determine your risk and the next steps in managing your health.
Who Is at Risk?
Anyone who is sexually active is at risk of HPV, regardless of gender or sexual orientation. However, the risk is higher among:
- Individuals with multiple sexual partners
- People who start sexual activity at a younger age
- Those who have sex without barrier protection
- Immunocompromised individuals (e.g., HIV-positive)
While women often face more severe consequences (like cervical cancer), HPV also causes health problems in men—including anal and penile cancers.
Symptoms of HPV Infection
HPV is often referred to as a “silent infection” because it typically doesn’t cause symptoms right away. However, depending on the type, symptoms may include:
- Genital warts: Small bumps or growths on the genitals, anus, or thighs
- Oral lesions: Warts or sores in the mouth or throat (less common)
- Abnormal pap smear results: Indicating potential precancerous changes
Cancers caused by HPV may take years to develop and often show no early symptoms, making screening essential.
How Is HPV Diagnosed?
HPV is typically detected through screening rather than symptoms. Diagnostic tools include:
- Pap smear: Screens for abnormal cells in the cervix
- HPV DNA test: Identifies high-risk HPV strains in cervical cells
- Visual inspection: For genital warts or oral lesions
There is currently no approved test for detecting HPV in men, although doctors can diagnose visible warts or related symptoms.
The Link Between HPV and Cancer
Persistent infection with high-risk HPV strains can cause changes in body cells, leading to cancers. Common HPV-related cancers include:
- Cervical cancer: Nearly all cases are linked to HPV, especially types 16 and 18
- Anal cancer: Rising in both men and women, often caused by HPV 16
- Oropharyngeal cancer: Cancer of the throat and tongue, increasingly linked to HPV among men
Early detection and vaccination have been key in reducing these risks.
HPV Vaccine: Your Best Protection
What Is the HPV Vaccine?
The HPV vaccine protects against the most dangerous strains of the virus. The most widely used version—Gardasil 9—covers nine HPV types, including both cancer-causing and wart-causing types.
Who Should Get the Vaccine?
- Girls and boys aged 11–12 (ideal age)
- Catch-up vaccination for teens and young adults up to age 26
- Adults aged 27–45 may benefit, based on risk factors (consult a doctor)
The vaccine works best when given before someone becomes sexually active, but it can still offer protection afterwards.
Is the Vaccine Safe?
Yes. The HPV vaccine has undergone extensive testing and has been proven safe and effective. Side effects are usually mild and include:
- Pain or swelling at the injection site
- Fever or headache
- Dizziness or fainting (especially in teens)
Like all vaccines, it’s monitored continuously for safety by health authorities such as the CDC and WHO.
Can HPV Be Treated?
There is no cure for HPV itself, but the effects of the virus can be managed:
- Genital warts can be treated with prescription creams, cryotherapy, or surgical removal
- Abnormal cells detected in pap smears can be removed to prevent cervical cancer
- HPV-related cancers are treated based on standard cancer protocols
Most HPV infections clear up within 1 to 2 years, especially in young, healthy individuals. Monitoring and regular screening are key.
Prevention Beyond the Vaccine
- Use barrier protection: Condoms reduce, but don’t eliminate, HPV transmission
- Limit number of sexual partners: Reduces exposure to multiple strains
- Regular screenings: Especially important for women aged 21–65
- Maintain immunity: Healthy lifestyle choices can support the immune system

FAQs About HPV
Can men get HPV?
Yes. Men can contract HPV and may develop genital warts or cancers. Vaccination is recommended for both boys and girls.
Is HPV the same as herpes?
No. HPV and herpes are different viruses. HPV causes warts and can lead to cancer, while herpes causes painful blisters but doesn’t cause cancer.
Can you have HPV without knowing it?
Yes. Most people with HPV don’t know they have it because there are no symptoms, making routine screening essential.
Does the HPV vaccine promote sexual activity?
No. Multiple studies have found no link between HPV vaccination and increased sexual activity among teens or young adults.
Do I still need pap smears if I’ve been vaccinated?
Yes. The vaccine doesn’t cover all cancer-causing types, so regular screening is still important.
Final Thoughts
HPV is a highly common but preventable virus. Vaccination, regular screening, and education are key to reducing its spread and the severe health risks it can cause. Whether you’re a teen, adult, or parent, taking proactive steps today can ensure a healthier tomorrow.
