HPV is the most common sexually transmitted infection (STI) in the United States, with an estimated 14 million new infections annually and 79 million Americans infected with HPV.
In addition to causing cervical cancer, HPV can cause genital warts and cancers of the vagina, vulva, penis, anus, throat and mouth. In the most recent government study, about 40% of women and men had some type of genital HPV infection.
High risk genital HPV (hrHPV) is relatively common, found in one in five women and one in four men.
