NHS Choices Condition

Warts are caused by different strains of the human papilloma virus (HPV). The virus is present in the skin cells of a wart.
How is the virus passed on?
The virus that causes warts is passed on through close skin-to-skin contact. It can also be passed on by indirect contact, for example, from objects such as towels and shoes. Warts are thought to be contagious for as long as they are present.
You can also spread warts to other parts of your own body. For example, you can spread the virus if you:
- scratch or bite a wart,
- bite your nails or suck your fingers, or
- shave your face or legs.
This can cause the wart to break up and bleed, making it easier for the virus to spread.
You are more likely to catch the infection if your skin is:
- damaged,
- wet, or
- comes into contact with rough surfaces.
For example, public swimming pools are a common place to catch verrucas. People with scratches or cuts on the soles of their feet are particularly vulnerable.
