A viral wart is a common skin growth caused by an infection with HPV (human papillomavirus). These are very common in school-aged children, people with suppressed immune systems and people with eczema; although they can appear at any age, on anyone. HPV is spread by direct contact with the skin or through autoinoculation.
There are several types of viral warts, including the common wart (regularly found on fingers ), plantar warts (found on the sole of the foot and toes), plane warts (found on face, hands and shins), filiform warts (found on the face ), and mucosal warts (found on lips and inside of cheeks).
