​Warts

Warts are small grainy skin growths that are rough to touch and often feature a pattern of tiny black dots which are small, clotted blood vessels. They are caused by human papillomavirus (HPV) and mostly found on your hands and fingers. Warts are most common in children, young adults and those with a weak immune system. They are highly contagious, usually transmitted from one person to another through direct contact with the warts or with something that has been in contact with the warts. You can also spread warts to the other part of your body if you are not careful.
