Disease 11. Warts: Benign Skin Growths Caused by a Virus
Symptoms of Warts
Warts are small, rough, benign skin growths that can appear on any part of the body. They vary in appearance, depending on their location and the type of human papillomavirus (HPV) that causes them. Common warts often appear on the hands and fingers, while plantar warts develop on the soles of the feet. Flat warts are typically smaller and smoother, often occurring on the face, arms, or legs.
Causes of Warts
Warts are caused by various strains of HPV, which can be contracted through direct skin-to-skin contact or by touching a contaminated surface. The virus enters the skin through tiny cuts or abrasions, causing the rapid growth of cells on the outer layer of the skin.
Treatment Options for Warts
Many warts will eventually disappear on their own without treatment. However, if a wart is bothersome or painful, various treatments can help remove it. Over-the-counter options include salicylic acid and cryotherapy (freezing), while a doctor may also perform in-office treatments such as stronger cryotherapy, laser therapy, or surgical removal. It’s essential to practice good hygiene and avoid direct contact with warts to prevent the spread of the virus. (11)
