Disease category
Anogenital human papillomavirus (HPV) infection is a sexually transmitted infection caused by HPV, and some types cause genital warts.
Key mechanism
The main modes of transmission are oral, vaginal, and anal sex with an infected person, and transmission can occur even in the absence of symptoms.
Main causes/related factors
There are several types of HPV; some types can cause genital warts, while other types can cause lesions associated with cancer.
Representative patterns
Typically, small flesh-colored bumps or clusters appear around the genitals, which may be flat or bumpy like cauliflower.
Individual differences
Sexually active individuals are at risk of infection, and the risk may vary depending on the type of sexual contact, exposure, vaccination status, etc.
Diagnosis
Infection or warts may pass without pain, but they can cause itching, burning, bleeding, or discomfort; warts may disappear on their own, remain as they are, or grow and increase in number.
Management
Diagnosis is usually made by confirming the shape and location of lesions through a physical examination or pelvic examination by medical staff.
Treatment/Research Status
There may be lesions so small they are invisible to the eye, and since HPV can remain in the body even after warts are removed, the disappearance of lesions does not mean clearance of infection or elimination of transmission risk.
Read Evidence
Management includes clinical evaluation of lesions, treatment of warts if necessary, explanation regarding the possibility of recurrence and transmission, and counseling on vaccination and use of protective barriers.
Key Precautions
Current treatment focuses on reducing or removing genital warts rather than eliminating HPV itself.

At a Glance

Anogenital human papillomavirus (HPV) infection is a sexually transmitted infection caused by HPV, and some types cause genital warts.

Typically, small flesh-colored bumps or clusters appear around the genitals, which may be flat or bumpy like cauliflower.

How the disease works

The main modes of transmission are oral, vaginal, and anal sex with an infected person, and transmission can occur even in the absence of symptoms.

There are several types of HPV; some types can cause genital warts, while other types can cause lesions associated with cancer.

Variations in presentation among individuals

Sexually active individuals are at risk of infection, and the risk may vary depending on the type of sexual contact, exposure, vaccination status, etc.

The broad framework of diagnosis and management

Infection or warts may pass without pain, but they can cause itching, burning, bleeding, or discomfort; warts may disappear on their own, remain as they are, or grow and increase in number.

Diagnosis is usually made by confirming the shape and location of lesions through a physical examination or pelvic examination by medical staff.

Current status of treatment

There may be lesions so small they are invisible to the eye, and since HPV can remain in the body even after warts are removed, the disappearance of lesions does not mean clearance of infection or elimination of transmission risk.

Management includes clinical evaluation of lesions, treatment of warts if necessary, explanation regarding the possibility of recurrence and transmission, and counseling on vaccination and use of protective barriers.

Current treatment focuses on reducing or removing genital warts rather than eliminating HPV itself.

How to read clinical trials

In follow-up, changes in lesions and recurrence must be confirmed, and treatment effectiveness, positive results, or adoption of standard care should not be judged solely by clinical trial registration or completion.

Points to verify during clinical consultations

In clinical practice, the location and changes of lesions, symptoms such as pain and bleeding, recent sexual contact and use of barrier protection, vaccination status, and pregnancy and childbirth-related situations can be assessed.
