What Causes Warts?

Warts emerge as a direct result of an infection by the human papillomavirus (HPV). HPV enters the top layer of the skin, causing cells to proliferate uncontrollably, which triggers the formation of the wart. The virus can be transmitted through skin-to-skin contact and can enter the skin through micro-tears or cracks. Therefore, situations where skin integrity is compromised can increase the risk of wart formation.

Common use areas, such as moist environments like swimming pools, gyms, and shared towels, are among the factors that can increase the risk of transmission of warts. Lack of personal hygiene and a weakened immune system can also increase susceptibility to wart formation. There are many different types of HPV, and the location of the wart is often dependent on the type of virus. For example, some types of HPV cause warts on the hands and feet, while others are associated with genital warts.
