Introduction to HPV
Human papillomavirus (HPV) is the most prevalent sexually transmitted infection (STI) in the United States.1 2 3 4 About 79 million Americans are infected, and there are about 14 million new infections each year. About 80% of sexually active women will have a high-risk HPV infection by age 50.
Risk factors associated with infection are common to other STIs, including new and multiple sexual partners and inconsistent condom use.
There are more than 100 types of genital HPV; about 13 are considered oncogenic (referred to as “high-risk”). Persistent high-risk HPV infection is the most important risk factor for cervical cancer precursors and cervical cancer.
