What is HPV?

Human papillomavirus (HPV) is a very common virus. There are over 100 strains worldwide. HPV can cause cancer in the cervix, vagina, vulva, penis, anus, mouth and throat. HPV can also cause genital warts. The HPV vaccine helps protect against these cancers and genital warts caused by nine types of the virus (6, 11, 16, 18, 31, 33, 45, 52 and 58).

Most people infected with HPV do not develop symptoms. Cervical cancer and other HPV-related cancers might not have signs or symptoms until they are advanced and hard to treat. For this reason, it is important for people to get regular health exams.
