70% all cervical cancer cases are due to persistent infection by HPV of two types, HPV16 and HPV18, however, both are preventable by vaccination.

HPV is the most common sexually transmitted infection globally. Most people are infected at some point in their lives. Persistent infection with high-risk HPV types 16 and 18 is a risk factor for developing carcinoma. In 2018, an estimated 569,000 new cases and 311,000 deaths occurred from cervical cancer worldwide. Around 85% of these occurred in low- and middle-income countries. In the United States, about 30,700 cases of cancer due to HPV occur each year.

About 1% of sexually active adults have genital warts, a common manifestation of HPV infection. While cases of warts have been described since the time of ancient Greece, their viral nature was not discovered until 1907.
