HPV is a very common and widespread virus, consisting of more than 150 related viruses. Nearly everyone will be infected in their lifetime. In fact, the Centers for Disease Control and Prevention (CDC) estimates that more than 90% of sexually active men and 80% of sexually active women will be infected with at least one type of HPV at some point in their lives. Around one-half of these infections are with a high-risk HPV type.1
- High-risk HPVs can cause cancer. About a dozen high-risk HPV types have been identified.
- Low-risk HPVs do not cause cancer but can cause skin warts on or around the genitals, anus, mouth, or throat.
Most high-risk HPV infections occur without any symptoms, go away within 1 to 2 years, and do not cause cancer. Some HPV infections, however, can persist for many years. Persistent infections with high-risk HPV types can lead to cell changes that, if untreated, may progress to cancer.2
