HPV infection causes warts. More than 100 varieties of human papillomavirus (HPV) exist.
Different types of HPV infection can cause warts on different parts of your body. For example, some types of HPV infection cause plantar warts on the feet, while other varieties of HPV infection are responsible for the warts that most commonly occur on the face or neck. More than 40 different strains of HPV affect the genital area.
Most HPV infections don't lead to cancer. But some types of genital HPV can cause cancer of the cervix — the passage between the vagina and the uterus. Vaccines can help protect against the strains of genital HPV most likely to cause genital warts or cervical cancer.
