Flat warts are caused by the human papillomavirus infection, commonly known as the HPV virus. This disease is highly contagious and recurrent; once it appears, it tends to grow on various parts of the body in most individuals. The most commonly used primary treatment method is laser removal of the warts, followed by the application of topical antiviral medications. This method is generally suitable for flat warts that are less numerous. Another method is wart vaccination therapy, which involves removing the flat warts and using them to create a vaccine that is implanted into the muscle of the patient, generating antibodies to fight against the flat warts. The last method involves the use of oral and topical medications, but this method is slower and requires long-term treatment. The treatment of flat warts also necessitates a long-term dietary avoidance of spicy and stimulating foods, increased physical exercise, and a stronger focus on immunotherapy.
