Human Papillomavirus (HPV)

Human papillomavirus (HPV) is the name of a group of viruses that includes more than 100 different types. More than 30 HPV types are sexually transmitted and can infect the genital area. Most people who become infected with HPV will not have any symptoms and will clear the infection on their own. Some of these HPVs are called "high-risk" types and can cause abnormal Pap tests, cervical cancer, and other anogenital cancers. Others are called "low-risk" types, and can cause mild Pap test abnormalities or genital warts, growths or bumps that may appear shaped like cauliflower. Two vaccines are available: a quadrivalent HPV vaccine is licensed for both males and females (protects against most cervical cancers and genital warts, as well as cancers of the anus, vagina and vulva); and a bivalent HPV vaccine (protects against most cervical cancers) is licensed for females only.
