A Plantar wart, or Verruca, is caused by the human papillomavirus (HPV) located on the sole of the foot. Plantar warts can be self-limiting, but treatment is generally recommended to lessen symptoms (such as pain), decrease duration, and reduce transmission.
Warts can be easily distinguished as they have no skin lines running through them are often more painful to squeeze than on direct pressure unlike corns. This is because warts generally contain nerves where as corns generally don’t. Warts may also have small black dots in their centre which represent the blood vessels within the wart itself, and are the reason why warts tend to bleed when scraped or picked at.
The HPV thrive in warm, moist environments. Spaces such as shower floors, locker rooms and pools are all hospitable environments for the virus. The virus also needs to have a point of entry into the skin of the foot, such as cracks in dry skin, cuts or scrapes.
