Yes, plantar warts are infections of the skin on the bottom of the foot caused by the human papillomavirus (HPV). Warts can be found anywhere on the foot, but are commonly found on the bottom of the foot and can be symptomatic if found in an area of pressure or friction. The virus causes lesions that look like thickened callused skin. When looking closely, you may also see dark spots, which tend to bleed easily when traumatized. Plantar warts are seen in all age groups, but they are most common among children 12-16 years of age and rare in the elderly. Risk factors for the development of plantar warts include use of public showers, skin trauma, and weakened immune system because of certain medications used or illness. Plantar warts can resolve spontaneously, but often require treatment. Warts do tend to spread on the foot and can infect other people. Treatment options vary, but most commonly are treated with salicylic acid, freezing, and laser removal. To help prevent plantar warts be sure to wear shoe gear in public places and perform daily foot hygiene. If you are unsure whether you have contracted a plantar wart, please call to make an appointment for an examination.
