Human papillomavirus (HPV) Treatment, symptoms, and causes. Common symptoms of some types of HPV are warts, especially genital warts. Genital warts may appear as a small bump, cluster of bumps, or stem-like protrusions. They commonly affect the vulva in women, or possibly the cervix, and the penis or scrotum in men.
HPV is the most common sexually transmitted infection (STI). HPV is a different virus than HIV and HSV (herpes). 79 million Americans, most in their late teens and early 20s, are infected with HPV. There are many different types of HPV. Some types can cause health problems including genital warts and cancers. But there are vaccines that can stop these health problems from happening.
How is HPV spread?
You can get HPV by having vaginal, anal, or oral sex with someone who has the virus. It is most commonly spread during vaginal or anal sex. HPV can be passed even when an infected person has no signs or symptoms. Anyone who is sexually active can get HPV, even if you have had sex with only one person. You also can develop symptoms years after you have sex with someone who is infected. This makes it hard to know when you first became infected.
