Viral Skin Diseases

Verruca vulgaris. Verruca vulgaris is the most common form of viral wart. Caused by the papillomavirus (HPV), three out of four people will develop this type of wart at some point in their lives. The warts spread through direct contact and while they may develop on any skin surface, most occur on extremities like hands, fingers, feet or toes. They may disappear on their own but can also be removed with a medical procedure.
