What is a verruca?
Warts are skin growths caused by an infection of the HPV virus that has entered through a cut or break in the skin. They commonly appear on hands and feet but can also develop on other areas. Warts are especially common among children. Usually they are not painful, but some may hurt and itch, especially if they are on the feet and are exposed to pressure when walking.
What causes warts?
The HPV virus causes warts. The virus is contagious and thrives in environments that are warm and moist. It can spread by direct or indirect contact and be transmitted if you touch a wart or through for example wet floors in public showers. However, not all people who come in contact with the virus develop warts.
There are a range of different types of warts, but some of the most common types are common warts and plantar warts which can appear alone or in groups. Usually, they go away on their own, but it can take months or years. Sometimes they need medical treatment to be resolved.
