Viral warts and corns, though similar in appearance, have significant differences. In terms of cause, viral warts are caused by an infection of the human papillomavirus and are contagious. Corns, on the other hand, are not contagious and are caused by long-term pressure, friction, or tight shoes. In terms of treatment, corns can often be cured through laser treatment or medication. Viral warts need to be treated with antiviral medications, along with physical treatment methods such as cryotherapy with liquid nitrogen. (Please use medication under the guidance of a doctor)
