Genital warts are one of the most common sexually transmitted infections in the United States and are caused by some types of human papillomavirus (HPV).

Genital warts—also known as anogenital warts or condylomata acuminata—are raised lesions that develop on the skin and mucous membranes after infection with some types of HPV, a virus transmitted through contact during sexual activity.

Most commonly, genital warts appear clustered as a few small, raised lesions, but their appearance varies. They can be flesh-colored, light and pearly, or dark purple, gray, or brown. There may be many or only one. They may be small and difficult to see or they may enlarge and combine into masses. They can be rounded bumps or flat plaques; they may be smooth or rough. They can be hidden in hair or folds of skin. They are generally painless but may itch or become irritated.
