Human papillomavirus infection is caused by any of a large group of related viruses that infect the skin and mucous membranes. Most infections cause no symptoms and clear on their own, but some strains cause warts, while a smaller number of high-risk strains are linked to the development of several cancers, including cervical cancer. It is transmitted primarily through intimate skin-to-skin contact, most often during sexual activity.
