Human Papillomavirus (HPV) Infection
Key Points
Anogenital warts are caused by human papillomavirus (HPV), most commonly types 6 and 11. HPV types 16 and 18 cause about 70% of cervical cancers and can cause cancer in other areas, including the vulva, vagina, penis, anus, and oropharynx. Diagnose warts by inspection; HPV testing is available to screen for cervical cancer. Treat warts with cytodestructive treatments, topical medications, or surgical excision. Treat cervical, vaginal, vulvar, or anal intraepithelial neoplasia with ablation or excision or manage with close surveillance. HPV vaccination is recommended for children and young adults.
