What is a common wart? Can it be treated? Is it harmful?

Common warts are benign skin and mucosal growths caused by infection with human papillomavirus (HPV), commonly known as "verruca" or "spiny warts." They mainly occur in children, young adults, and individuals with weakened immune systems. Although they can spontaneously regress, common warts may also be treated through physical therapy, medication, or surgical intervention. Regarding potential harm, common warts primarily affect appearance and may cause social and psychological distress for patients. Additionally, large-area warts can easily bleed when touched or rubbed, leading to wound ulceration and infection. Long-standing, non-healing warts may also affect the immune system, reducing the body's ability to defend against viral invasion. Therefore, although common warts often resolve spontaneously, patients should maintain good personal hygiene, avoid cross-infection, and seek medical assistance when necessary.
