Some of these viruses are called "high-risk" types, and may cause abnormal Pap tests.
They may also lead to cancer of the cervix, vulva, vagina, anus, or penis.
More than 30 of these viruses are sexually transmitted, and they can infect the genital area of men and women including the skin of the penis, vulva (area outside the vagina), or anus, and the linings of the vagina, cervix, or rectum.
Most people who become infected with HPV will not have any symptoms and will clear the infection on their own.
Genital HSV-2 infection is more common in women (approximately one out of four women) than in men (almost one out of five).
