Overview
Warts are growths of the skin and mucous membranes (the mouth or genitals) that are caused by over 100 types of the human papillomavirus (HPV). Common warts are usually found on areas of the body prone to trauma, such as the elbows, knees, and hands. Because warts are usually painless and most go away on their own (although this may take a few years), therapy is not necessary.
Warts are usually acquired from person-to-person contact. The virus is not highly contagious but can cause an infection by entering through a small break in the skin. The virus is rarely transferred by touching an object used by an infected person. You may acquire warts by sharing towels or other intimate items as well as going barefoot when walking in public places. Additionally, it is possible to spread warts on your own body (autoinoculate) by scratching or picking at warts.
