A plantar wart, also known as verruca, is a small growth on the skin that develops when the skin becomes infected by a virus. Plantar warts are caused by direct contact with human papilloma virus, more commonly known as HPV, which invades the skin through small or invisible cuts and
abrasions. This virus thrives in warm, moist environments.
Like any other infectious legion, plantar warts are spread by touching, scratching, or by contact with skin shed from another wart.
Generally, there are two types of plantar warts:
- Solitary Wart: a single wart that may increase in size, and potentially multiply in number.
- Mosaic Warts: a cluster of several small warts, growing closely in one area. This is generally more difficult to treat.
