Genital warts
HPV is a different virus than HIV and HSV (herpes). HPV is so common that nearly all sexually active men and women get it at some point in their lives. There are many different types of HPV. Some types can cause health problems including genital warts and cancers. 1. The strains of HPV known to cause genital warts are low-risk HPV 6 and 11, while the strains of HPV associated with cancer include high-risk HPV 16, 18, 31, 33, 45, 52 and 58. 2. HPV is a virus which is passed skin-to-skin through sexual intercourse or other forms of skin-to-skin contact of the genitals. Other types of HPV can cause warts and verrucas. These types of HPV are sometimes called the wart virus or genital wart virus and they include types 6 and 11. Warts and verrucas are most common on the hands and feet, in the genital area and around the anus. But they can be on any part of the body. HPV stands for human papillomavirus. These viruses are the direct causes of HPV and infect the skin or mucous membranes (mucous membranes are the moist, inner lining of some organs and body cavities, such as the nose, mouth, lungs, and stomach). Human papilloma virus (HPV) is the major cause of cervical cancer. There are many different types of HPV. Some types of HPV cause genital warts and are sometimes called the genital wart virus. The types of HPV that cause warts do not usually cause cell changes that develop into cancer. Some other types of HPV are considered high risk for cancer of the cervix. Certain HPV types are classified as high-risk because they lead to abnormal cell changes and can cause genital cancers: cervical cancer as well as cancer of the vulva, anus, and penis. In fact, researchers say that virtually all cervical cancers -- more than 99% -- are caused by these high-risk HPV viruses. There are more than 100 types of HPV. About 30 or so types can cause genital infections. Some can cause genital warts; other types can cause cervical or other genital cancers. The other 70 or so HPV types can cause infections and warts elsewhere on the body, such as on the hands.
