Viral warts, also known as verrucae, are benign epithelial tumors caused by human papillomavirus (HPV) infection. These warts can appear on various parts of the body, including the hands, feet, and face, and are characterized by their rough, raised surfaces. HPV is a common viral infection, with over 100 different types, some of which are more likely to cause warts than others. The transmission occurs through direct contact with the virus, often in warm, moist environments such as swimming pools or communal showers. While viral warts are generally harmless, they can be bothersome and may lead to complications such as secondary bacterial infections or discomfort, especially when located on weight-bearing areas like the soles of the feet (plantar warts). Treatment options include topical therapies, cryotherapy, and surgical removal, but many warts resolve spontaneously over time. Vaccination against HPV can help prevent certain types of HPV infections, particularly those associated with genital warts and cervical cancer, but it does not eliminate existing warts. Understanding the nature of viral warts is crucial for accurate diagnosis, treatment, and coding.
