Which viral infection is specifically associated with warts found on the feet?

The presence of warts on the feet is specifically associated with verrucas, which are caused by human papillomavirus (HPV). Verrucas, also known as plantar warts, typically appear on the soles of the feet and are characterized by their tough, thickened appearance due to pressure from walking and standing. The HPV strain that leads to verrucas is distinct from the strains that cause warts in other areas of the body.

In contrast, tinea pedis refers to a fungal infection commonly known as athlete’s foot, which does not produce warts. Herpes simplex is a viral infection that primarily causes sores around the mouth or genitals, while impetigo is a bacterial skin infection that leads to blisters and sores, not warts. Thus, verrucas are the specific type of wart found on the feet, directly linking this term to the condition described in the question.
