Types of HPV

More than 100 different HPV types have been identified; at least 30 of them can be transmitted sexually. The symptoms a person experiences, as well as the associated conditions that may develop, depend on the virus a person is infected with. A vaccine is available to help protect women against high-risk types, since these viruses often can lead to cervical cancer.
