Plantar warts are a contagious disease that can infect others. Plantar warts are a skin condition caused by HPV (human papillomavirus) infection that occurs on one or both soles of the feet, and is characterized by flat papules or plaques. The main sources of infection are healthy carriers of the virus and patients, broken skin or mucous membranes in direct contact with the patient’s lesions or indirect contact with objects infected by the virus (such as slippers, towels, bath towels, etc.). In addition, patients may infect other parts of their own skin. Patients with plantar warts should seek medical attention in a timely manner and follow the doctor’s instructions for appropriate treatment, so as to avoid the condition from continuing to develop, affecting daily life or infecting others.
