Warts :: Types of warts
Warts, also called verrucas, are small growths caused by human Papilloma viruses. The viruses invade skin cells and encourage them to multiply thus creating thickened areas of skin. Warts usually occur on the hands or feet and are generally harmless. However, some types affect the genitals and are more serious. Thus the source of infection is other infected individuals. These occur both in adults and children.
