HPV - Human Papillomavirus

Every year, nearly 9 million people under the age of 25 get a new STI (sexually transmitted infection).[1] One of these infections is human papillomavirus (HPV) infection. If you've had sex, you could have an STI. Some STIs cause symptoms. Others don't. You could have one and not know it. Some STIs make you sick today and others can cause problems later in life. The include serious problems like cancer or infertility. Some can even kill you.

What is HPV and how do you get it?
Human papillomavirus (HPV) is a very common viral STI in the US. You get HPV from having sex with an infected person. You can also get it from just "fooling around." Most infected people have no symptoms. But, even without symptoms, they can pass on HPV.

Am I safe if I only have oral or anal sex?
HPV can also be passed during oral or anal sex.[2,3]

What happens if I'm infected?
If you are like most people, you will have no symptoms at all. Some people with HPV have warts. These are usually in the genital area. People with HPV can get cervical, penile or anal cancer.[4] Babies can get HPV infection from their mothers during childbirth. They can even get warts in their throats.

How do you treat HPV?
Most people with HPV infection clear it on their own. However, some people will go on to develop warts or cancer. Warts can be treated. However, they may return. For females, a Pap smear can detect changes caused by HPV before they turn into cancer. Abnormal Pap smears and cervical cancer can be treated. The earlier you are treated, the more likely you are to be cured. All sexually active females should talk to a doctor about when to start having regular Pap smears.

Am I safe if I always use a condom?
If you always use condoms for vaginal sex, you can cut your chance of getting HPV by about half.[5-8] To date, there is no evidence that condoms reduce your chance of getting HPV during oral or anal sex.

Is there anything else I can do to reduce my chance of getting infected?
HPV vaccine is available and is recommended for young women. However, vaccination does not protect against all types of HPV that cause cancer and warts. How long it works is unknown.[9-10]

What can I do to avoid getting infected?
Avoid sexual activity if you are single. Be faithful to one uninfected partner for the rest of your life. Already had sex? See a doctor and get checked out.
