What are Warts?
Warts are growths on the skin and are a common problem, mainly in young people.
What Causes Warts?
Warts are caused by infection with the human papilloma virus. There are many different types of human papilloma virus, each causing different types of warts. For example, common warts are associated with HPV 1, 2 and 4. Plantar warts on the soles of the feet (or verruca warts) are often associated with HPV 1, 2, 4 and 60.
Common warts are particularly common in younger people – as immunity develops to the wart virus, they become less common in adults.
Warts generally affect the skin, but also can occur in the anogenital region. Some sub-types of wart virus, especially HPV 16 and 18, can be associated with cancer of the cervix, anus and genital cancers, as well as some mouth and throat cancers.
