Warts are a very common skin condition, known as growths that occur when a viral infection triggers excessive production of protein in the skin. These triggered growths are caused by various strains of Human Papilloma Virus (HPV), that are transmitted, primarily, by direct contact with infected persons or contaminated objects. The virus replicates in the upper layers of the skin and causes focal disorganized growth, leading to the thickened, firm surface of the clinical wart. This results in a raised, hardened bump that may be roughly textured or smooth like a blister.
A wart can appear anywhere on the body. Those on the feet are called plantar warts. These are generally the only type that is painful. A wart may disappear without intervention, therefore a “wait and see” approach can be attempted, before seeking professional treatment, unless a wart is causing discomfort, is large or carries unusual characteristics. However, if you think you might have genital warts, you should see a dermatologist immediately.
