What are the different types of HPV?

ANSWER

Each HPV virus has its own number or type. The term "papilloma" refers to a kind of wart that results from some HPV types.

HPV lives in thin, flat cells called epithelial cells. These are found on the skin's surface. They’re also found on the surface of the vagina, anus, vulva, cervix and head of the penis. They’re also found inside the mouth and throat. About 60 of the 100 HPV types cause warts on areas like the hands or feet. The other 40 or so enter the body during sexual contact. They’re drawn to the body's mucus membranes, such as the moist layers around the anus and genitals.
