Plantar warts on the feet are often skin diseases caused by infection of the feet with the human papilloma virus, mostly due to trauma to the feet or infection caused by friction, pressure, or excessive sweating. In general, it has little to do with other bodily functions and is less indicative of a problem in the patient’s body. However, usually, the lower the immune system, the more likely the patient is to be infected by bacteria or viruses, etc. Therefore, patients with plantar warts on their feet can take proper supplements to improve their immune system. Patients are advised to treat the disease early, as it may cause damage to other body functions if the virus is not effectively removed. The more common treatment methods include topical medication, such as salicylic acid ointment and fluorouracil ointment, as well as liquid nitrogen freezing treatment, laser treatment and scraping treatment. It is recommended that patients keep their feet dry to facilitate the recovery of the disease. Because plantar warts are contagious diseases, it is recommended that patients’ feet or items that have come in contact with the patient’s feet after the disease, such as shoes, socks, towels, etc. avoid contact with others to avoid cross-infection.
