What is Genital HPV?

HPV (human papillomavirus) is a very common family of viruses. Some types(strains) of genital HPV can cause abnormal changes (dysplasia) in the cells of a woman’s cervix, or in a woman's or man's anus. In a small number of women, these cervical changes can lead to cancer if not treated. Some people also develop anal cancer. Also, certain strains of HPV can cause genital warts. Many people carry HPV. But it often has no symptoms. The virus may first be found when signs of dysplasia or warts are found during a Pap test.

Dysplasia develops when cervical cells change in ways that are not normal.

Warts on the cervix can be detected with a Pap test.

Warts around the genitals may be visible. These external warts can affect the vulva, vagina, and anus.

How does HPV spread?

HPV lives inside skin and mucous membranes. It spreads when skin carrying the virus touches other skin. Genital HPV most often spreads during sexual contact. Condoms and other barriers help protect against the spread by preventing skin contact. But condoms may not cover all affected skin. So they may not provide complete protection. There is no cure for HPV. Even if symptoms go away, the virus may stay in the body. It often doesn’t cause symptoms. So many people who have HPV don’t even know it.

When dysplasia occurs

The cervix is the narrow canal at the bottom of the uterus. It’s made up of layers of cells that normally change as they grow. Dysplasia occurs when HPV causes some cervical cells to change in abnormal ways. These abnormal cells can be found with a Pap test. Left untreated, abnormal cells can develop into cancer. A similar process can occur in the anus if there is HPV present.

When warts form

Certain strains of HPV can make skin cells reproduce more often than they should. These extra skin cells build up into warts. Warts can form on the cervix. They can also form around or inside the genitals and anus, and sometimes in the mouth. Treating warts helps keep HPV from spreading to sex partners.

HPV vaccine

A vaccine is available that protects against certain strains of HPV. It is strongly advised that all U.S. teens and young adults get the HPV vaccine. It can be given up to age 45. Your healthcare provider can tell you more.
