Warts are small bumps, caused by a virus, that are highly contagious.

The American Podiatric Medical Association suggests how to reduce your risk of developing warts on the feet:

• Don’t walk around barefoot.
• Each day, wear a clean pair of socks and alternate your shoes.
• Wash feet regularly, and dry them thoroughly.
• Regularly inspect children’s feet.
• If someone else has warts, avoid direct contact with their skin.
• Let your doctor know about warts, growths or other changes in your skin.
