Flat warts are caused by human papillomavirus infections. They are highly contagious and recurrent, and most people do not respond well to long-term treatment. It is essential to seek treatment at a regular hospital's dermatology department. You can visit the dermatology department of the local hospital, where the doctor can examine the condition and then develop a treatment plan. If there are fewer warts, laser treatment can be chosen; if there are many, oral and topical medications can be used; other options include wart burial or wart immunotherapy. It is also beneficial to prevent recurrence by strengthening exercise, enhancing immunity, avoiding spicy and stimulating foods, and avoiding staying up late.
