Common warts are local growths in the skin that are caused by
human papillomavirus (HPV) infection. They should be distinguished from sexually transmitted (genital) warts, which are caused by other HPV types.
Types of warts include common warts, flat warts,
plantar warts, periungual warts, and filiform warts.
Warts typically disappear on their own with time, but it may take years.
Warts respond variably to treatment measures.
Over-the-counter treatments for warts include salicylic-acid preparations and freezing kits.
Common warts are local growths in the skin that are caused by human papillomavirus (HPV) infection. There are over 100 types of HPVs. Some HPV types infect the genital tract and oral tissues, producing genital warts and
cancers in these areas. Other, different HPV types
are responsible for common skin warts and are not associated with cancer. Although warts are considered to be contagious, it is common for just one family member to have them. In addition, they often affect just one part of the body (such as the hands or the feet), but they can be spread to other areas by picking them.
What are some types of common warts?
There is the familiar type of dome-shaped warts on the backs of fingers,
toes, and knees.
Plantar warts are found on the sole or plantar surface of the foot (not to be mislabeled as a Planter's wart).
Flat ("plane") warts may arise on the face, legs, and other parts of the body, often in large numbers.
Periungual warts are warts around or under the nail.
Filiform warts typically
appear as a single long stalk, often on the face.

The warts commonly seen on the skin are caused by a viral infection. The
culprit is one of the HPVs (human papillomaviruses) that can be spread from
person to person or be acquiredthrough contact with a contaminated surface.
