HPV infection

Other names: Human papillomavirus infection


HPV infection causes warts. More than 100 varieties of human papillomavirus (HPV) exist. Different types of HPV infection can cause warts on different parts of your body. Most HPV infections don't lead to Cancer, but some types of genital HPV can cause Cancer of the cervix.


In most cases, your body's immune system defeats an HPV infection before it has a chance to create any warts. When warts do appear, they may vary in appearance depending on which variety of HPV is involved.


HPV infection occurs when the virus enters your body through a cut, abrasion or small tear in the outer layer of your skin. Genital HPV infections are contracted through sexual intercourse, anal sex, and other skin-to-skin contact in the genital region.


Risk factors for HPV infection include the number of sexual partners, age, weakened immune systems, damaged skin, and personal contact with infected surfaces.


Complications of HPV infection may include oral and upper respiratory lesions and various types of cancer.


Before your appointment with a healthcare provider, prepare questions about the likely cause of symptoms, tests needed, prevention strategies, medication alternatives, follow-up plans, and additional resources.


Diagnosis of HPV infection may involve visual inspection or tests such as vinegar solution test, Pap test, and DNA test to identify high-risk HPV strains linked to cancers.


Warts often disappear without treatment but may require medications like salicylic acid or procedures such as cryotherapy if persistent. Surgical removal may be necessary in some cases.


Preventive measures include avoiding picking at warts or biting nails for common warts, wearing shoes in public areas to prevent plantar warts, and practicing safe sex to reduce the risk of genital warts. Vaccines like Gardasil and Cervarix are available to protect against certain HPV strains causing genital warts and cervical cancer.
