Verrucas (also known as plantar warts) are caused by a type of human papillomavirus (HPV). They are common skin warts that usually appear on the feet, although they can also occur on other parts of the body. Depending on the individual as well as the size and location of the verruca, verrucas can last anywhere from a few weeks to several years.
The majority of verrucas tend to resolve without treatment within 2 years. However, treatment may be necessary if the verruca is painful or cosmetically displeasing. Treatments include over-the-counter creams, salicylic acid, cryotherapy, laser therapy, electrosurgery, and immunotherapy.
The best way to prevent verrucas is to wear shoes or sandals in public places such as locker rooms, swimming pools, and showers. It is also important to keep the feet clean and dry. Avoiding contact with someone else's verrucas is also important to prevent the spread of the virus.
In some cases, verrucas can become chronic and last for many years. If you have a verruca that has not responded to treatment or has been present for more than two years, you should seek medical advice from a dermatologist or podiatrist. They can provide more advanced treatment options that may be more effective in eliminating the verruca.
