Human Papiloma Virus (HPV)
Human papilloma virus (HPV) infection is the most important risk factor for cervical cancer. This virus can infect the skin’s surface cells, and those that are in the genitals, anus, mouth, and throat, but cannot infect the blood or internal organs like the heart or lungs.
HPV can be transmitted from one person to another during skin contact. One way in which HPV is transmitted is through sex, including vaginal, oral, and rectal sex. The different types of HPV (6 and 11) cause warts in different parts of the body. Some types cause common warts on the hands and feet; Other types tend to cause warts on the lips or tongue.
