What is HPV?
human Papillomavirus (HPV) is a common viral infection transmitted through skin-to-skin contact, most often during sexual activity. There are over 200 types of HPV, with about 40 affecting the genital areas of men and women. While many HPV infections clear up on their own, some can lead to health problems, including genital warts and certain types of cancer.
How is HPV Transmitted?
HPV is primarily spread through direct contact, usually during vaginal, anal, or oral sex with someone who has the virus. It can be transmitted even when there are no visible symptoms. As HPV can infect areas not covered by a condom, condom use doesn’t provide complete protection, but it significantly reduces the risk of transmission. According to the Mayo Clinic, even a single sexual partner can transmit the virus.
The Link Between HPV and Cancer
Certain high-risk HPV types can cause several cancers. the most well-known link is to cervical cancer; nearly all cases of cervical cancer are caused by HPV. However, HPV can also cause cancers of the vagina, vulva, anus, penis, and oropharynx (back of the throat, including the base of the tongue and tonsils). The Centers for Disease Control and Prevention (CDC) estimates that about 14 million new HPV infections occur each year in the United States.
| Cancer Type | HPV-Associated Percentage (US) | Source |
|---|---|---|
| Cervical | ~99% | CDC |
| Anal | ~95% | CDC |
| Oropharyngeal | ~70% | CDC |
| Vaginal | ~50% | CDC |
| Vulvar | ~50% | CDC |
