Genital HPV usually results in genital warts (condylomas). Genital warts are very contagious, and are spread through sexual contact - during oral, genital, or anal sex with an infected partner. Genital warts are the most easily recognized sign of a genital HPV infection. However, a genital HPV infection can be present without genital warts. Often HPV infections do not have visible signs and symptoms resulting in the disease being transmitted unknowingly. It is possible to be exposed to an HPV and not develop genital warts, but become a carrier of the virus.
Genital warts usually occur within 3 months of sexual contact with an infected person. The warts occur on the inside and outside of the vagina, on the cervix, or around the anus in women. In men they are usually on the tip of the penis, shaft of the penis, scrotum, or around the anus. Genital warts are less common in men than in women. It is believed that one in four women are infected by the virus in the genital tract. The warts can also develop in the mouth or throat of a person who has had oral sex with an infected person, but this is rare. Genital warts most often occur in clusters and are very tiny.
