Understanding Warts
What causes warts?
Warts are small growths on the skin caused by certain strains of the human papillomavirus (HPV). The virus enters the body through tiny cuts or breaks in the skin and can trigger extra skin cell growth, resulting in a wart.
Warts can develop on various parts of the body and often differ in appearance depending on the type and location. They are generally considered harmless, although some can be uncomfortable or bothersome.
Common types of warts
There are several different kinds of warts, and each has its own characteristics:
-
Common warts usually appear on the hands or fingers and have a rough, raised surface.
-
Plantar warts occur on the soles of the feet and may grow inward due to pressure from walking, which can make them uncomfortable or even painful.
-
Flat warts are smaller, smoother, and flatter than other types, and they often appear on the face, arms, or legs, sometimes in clusters.
-
Filiform warts are long and narrow, usually found on the face around the eyes, mouth, or nose.
- Periungual warts form around the fingernails or toenails and can affect nail growth if persistent.
Understanding the differences between these types can help people recognise why warts vary in size, shape, and location.
