Are All Warts Caused by HPV?

The majority of warts are caused by various strains of the Human Papillomavirus (HPV). HPV is a group of viruses that can infect the skin and mucous membranes, leading to the development of warts. Different types of HPV cause different types of warts. The most common types of warts caused by HPV include:

  • Common Warts (Verruca Vulgaris): These warts typically appear on the hands and fingers and are often rough, raised, and flesh-colored. They are usually caused by HPV types 2 and 4.
  • Plantar Warts: Plantar warts develop on the soles of the feet and can be painful because they are pressed into the skin’s surface by body weight. They are usually caused by HPV type 1.
  • Flat Warts (Verruca Plana): These warts are small, flat, and smooth, often flesh-colored or slightly pigmented. They can appear in large numbers on the face, arms, and legs. Flat warts are usually caused by HPV types 3, 10, 28, and 49.
  • Genital Warts: Genital warts are a sexually transmitted infection (STI) and are caused by specific types of HPV, primarily HPV types 6 and 11. They can appear on the genitals, as well as in the anal and oral regions.

While most warts are caused by HPV, not all skin growths are warts, and not all warts are caused by HPV. Some growths may resemble warts but have different causes. Additionally, some warts may spontaneously resolve without treatment, while others may persist or spread if left untreated.

If you have a skin growth or lesion that you suspect may be a wart or if you’re concerned about any changes in your skin, it’s advisable to consult a healthcare professional or dermatologist for proper diagnosis and appropriate treatment options.
