Common warts, even when picked off, are very likely to regrow, as they are benign growths caused by an infection of the skin and mucous membrane with the Human Papillomavirus, or HPV. Due to their viral nature, they tend to recur easily. Common warts, also known as verruca vulgaris or plantar warts, are typically caused by HPV type 2 and mainly occur between the ages of 5 and 20. They can appear on any part of the body due to autoinoculation and are most commonly found on the hands and feet. These areas are susceptible due to frequent injuries or prolonged exposure to water, which are common triggering factors. After a wart is removed, the surrounding areas might already be infected, potentially leading to new warts appearing over time.
