A verruca, commonly known as a wart, is a small, benign growth on the skin caused by the human papillomavirus (HPV). These growths often appear on the hands, feet, or other areas and can vary in size and texture. Warts are typically rough and raised, and they may be skin-colored or darker. Verrucas are contagious and can spread through direct contact or by sharing personal items like towels or shoes. While they are generally harmless, some people may choose to treat them for cosmetic reasons or if they cause discomfort. Treatment options include over-the-counter medications, cryotherapy, or laser therapy.
