What are warts? What causes warts? Are warts contagious?

Warts are local growths in the skin that are caused by human papillomavirus (HPV) infection. There are over 100 types of HPV. Some HPV types infect the genital and oral mucosa and produce large, unpleasant masses, some of which may become cancerous. Other, HPV types are responsible for common skin warts and are not associated with cancer. Although warts are considered to be contagious, it is not uncommon for just one family member to have them. In addition, they often affect just one part of the body (such as the hands or the feet), but they can be spread to other areas by picking them.
