Verruca: A wart by another name, a local growth of the outer layer of the skin (the epidermis) caused by a virus. The virus of warts (a human papillomavirus) is transmitted by contact. The contact can be with a wart on someone else or one on oneself (autoinoculation).
Warts are tumors or growths that occur on the skin after the keratin component grows too fast. This is usually brought about by a virus called Human Papilloma Virus, otherwise commonly known as HPV. They are very contagious and can easily be passed from one person to another via skin to skin contact.
