Plantar warts may be contagious to others if they are not broken. Plantar warts are benign growths that appear on the skin of the plantar region of the foot as a result of infection by the human papilloma virus. The disease is contagious and can be spread through direct or indirect contact, such as direct contact with the affected area of the plantar warts, touching other parts of the body after touching the affected area, or sharing shoes and socks with the patient, all of which are potentially contagious. Therefore, plantar warts can be transmitted to others even if they are not broken. It is recommended that patients with plantar warts keep the affected area clean and dry, change shoes and socks frequently, and disinfect and expose them to sunlight. In addition, avoid sharing household items with others, avoid scratching the affected area, so as not to pass on to others or cause their own transmission. For those who have plantar warts, it is advisable to consult a doctor at a regular hospital to learn more about the matter, and cooperate with the doctor to carry out standardized treatment.
