There are more than 140 types of Papillomavirus (HPV) detected in humans. About 40 types can infect the genital areas such as the vulva, vagina, cervix, rectum, anus, penis and scrotum, as well as the mouth and throat. These types of HPV are spread during sexual intercourse.
-Two types of HPV (types 6 and 11) cause most cases of genital warts in women and men.
-More than 10 strains of HPV can lead to cancer, of which 2 specific strains (types 16 and 18) lead to the majority of cancers. This is called high-risk HPV. Cervical cancer is most commonly associated with HPV, but HPV can also cause cancers of the vulva, vagina, penis, anus, mouth, and pharynx. HPV types 16 and 18 are also the two main types that cause cervical cancer and are also the cause of cancers such as: vulvar cancer (50%), vaginal cancer (65%), cancer oropharynx (70%).
