<unk> s are a sexually transmitted infection caused by certain types of human papillomavirus (HPV). They are generally pink in color and project out from the surface of the skin. Usually they cause few symptoms, but can occasionally be painful. Typically they appear one to eight months following exposure.<unk> s are the most easily recognized symptom of<unk>  HPV infection. HPV types 6 and 11 are responsible for causing majority of<unk> s whereas HPV types 16, 18, 31, 33, and 35 are also occasionally found. It is spread through direct skin-to-skin contact, usually during oral,<unk> , or anal sex with an infected partner. Diagnosis is generally based on symptoms and can be confirmed by biopsy. The types of HPV that cause cancer are not the same as those that cause<unk> s. Some HPV vaccines can prevent<unk> s as may condoms. Treatment options include creams such as podophyllin, imiquimod, and trichloroacetic acid. Cryotherapy or surgery may also be an option. After treatment<unk> s often resolve within six months. Without treatment, in up to a third of cases they resolve on their own. About 1% of people in the United States have<unk> s. Many people, however, are infected and do not have symptoms. Without vaccination nearly all sexually active people will get some type of HPV at one point in their lives. The disease has been known at least since the time of Hippocrates in 300 BC.
