Warts are caused by some types of the human papilloma virus (HPV), causing a rapid proliferation of the cells in the skin. This results in the development of benign protuberances, which are extremely contagious, unattractive but not dangerous.
Warts have a hard surface, can be round or have irregular shape, flat or bumpy. They can also be white, gray or brown. Depending on the clinical picture and their position they are distinguished in common, flat and plantar.
Depending to the type of virus warts develop in different body parts. But mainly they appear on the hands, feet and face but the can contaminate any part of the body.
Warts are spread through direct skin contact or indirectly with objects of common use or or in public places e.g. public baths and pools etc. Generally warts have an incubation time of 2-9 months.
