Common warts are tiny, grainy skin growths that occur often on your hands or fingers and are one of the eight types of warts. They are usually rough to touch, they also feature a certain pattern of tiny black dots called seeds. Those seeds are small, clotted blood vessels. Common warts are usually transmitted by touch and are caused by a virus. 

Young adults, children, and individuals who have a weakened immune system are likely to get common warts. After a certain period, common warts usually disappear on their own, but a lot of people choose to remove them because they find them embarrassing or bothersome.

Causes of Common Warts

Common warts are usually caused by an infection with the Human PapillomaVirus (HPV). There are more than 100 types of human papillomavirus, but only a few cause warts on your fingers and hands. Other types of human papillomavirus are more likely to cause warts on your skin, feet, and other areas of your mucous membranes. Most types of human papillomavirus usually cause relatively harmless conditions such as common warts.

Common warts are transmitted from skin-to-skin contact with individuals who have warts. If you have the infection, you can spread the virus to other places in your own body. Also, you can get the wart virus indirectly by coming in contact with something that another person’s wart touched, such as a piece of exercise equipment or a towel. Common warts can be avoided by taking some general precautions. The common wart virus usually spreads through breaks in your skin, like scrapes or hangnails.
