Warts are tumours or growths of the skin caused by a virus. They can occur on any part of the body and have a rough surface on which tiny, black dots can often be seen. Warts are common and harmless. However, warts on the soles may become painful on pressure or walking as they grow larger and deeper into the skin. Warts may also bleed if injured and are potentially contagious. They can spread from one part of the body to another, or to other people. Therefore it is important not to scratch the warts. Sometimes, warts may disappear by themselves, especially in children.
What Causes Viral Warts?
Viral Warts are caused by a viral infection (human papilloma virus) present in the outermost layer of the skin.
Treatment for Viral Warts
There is no perfect treatment for warts, since we are unable to kill the wart virus except by destroying the skin cells in which they live and multiply. This can be done by surgery, laser ablation, electrocautery (destroying with a weak current), cryotherapy (freezing) or with chemicals like salicylic acid. The treatment to be used depends on the subtype, location and size of the warts and the judgement of the dermatologist. A newer immunomodulating gel that improves the body’s defence against the virus is useful for certain types of warts.
