CAUSES AND SYMPTOMS OF WARTS
Warts are caused by human papillomavirus (HPV). Like any virus, warts are spread through contact. The virus enters the body through tiny cuts or cracks on the bottom of the foot. This can occur when walking barefoot on surfaces where the virus is present. The virus thrives in warm and moist environments, making locker rooms and swimming pools a common source of infection.
It can take as long as six months to develop a wart after the skin has come into contact with the virus, making it difficult to identify the source of the infection. Individuals can reduce their chances of contracting a wart by avoiding walking barefoot, especially in public spaces. Keeping the feet clean and dry can also help.
Symptoms of plantar warts include:
- Small, fleshy growths on the bottom of the foot, which may be rough or grainy.
- Hard, thickened skin, where a wart has grown inward.
- Black pinpoints in the center of the growth, which are clotted blood vessels.
