Warts are small growths of skin which can appear on almost any area of the body. They can be found on the hands, elbows, knees, the face, the feet as well as the genitalia.
These lesions are linked to an infection of the skin by the HPV virus ( human papillomavirus ), which has many variations.
They are divided into common ( or vulgar ) warts, plantar warts, filiform and flat warts. This distinction is made with respect to their appearance, where they are on the body and the type of HPV virus causing them.
Skin warts are common, and can be found amongst 25% of the French population, particularly among children aged 5 to 15, and adults over the age of 25.
They are benign and do not lead to skin cancer.
The main source of infection is the wart itself, thanks to the spread of infected flakes of skin. Warts are transmitted between humans by skin contact.
