Common warts are small, rough bumps that can grow anywhere on the skin. Warts are caused by the human papillomavirus and are contagious. Warts are usually not painful, but visible warts are unsightly and embarrassing to most people.
There are five types of warts:
Flat warts develop primarily on the face and forehead
Genital warts arise in the pubic area and directly on the genitals
Plantar warts develop on the soles of the feet
Subungual and periungual warts develop under or around the fingernails and toenails
Genital warts are highly contagious and can be transmitted during oral, vaginal or anal sex. In women, warts can be undetected on the cervix and transmitted to a sexual partner.
