Wart virus infection can cause visible genital or anal warts, or it can cause no symptoms.
Infection is difficult to treat, and can have serious consequences for women.
Condom use contributes to preventing the spread of wart virus infection. Genital and anal warts are common diseases transmitted sexually. HPV infection may cause an outbreak of visible warts, but more commonly it causes no signs at all. This explains why HPV infection spreads easily amoung sexually active people. In women, undetected HPV infection on the cervix may lead to cell changes that, if untreated, can lead to cervical cancer.
