What causes Common warts?
Simple Warts most often occur on the hands and feet but may also occur on other parts of the body. Warts on the soles of the feet and also known as Verrucae.
Warts are caused by the ‘human papilloma virus’ (HPV). HPV is better known for types 16 & 18 that may cause cervical cancer. Types 4 & 11 may cause genital warts. HPV vaccine given to Queensland kids at school in year 8 covers these HPV types – and more.
Simple warts usually caused by HPV types 1,2,4, 60 & 63. These are not included in HPV vaccinations.
The virus enters the skin through tiny breaks in the skin surface. Moisture and maceration of the skin on the feet encourage infection with the wart virus. Warts are ‘caught’ by direct or indirect contact with HPV-infected skin scales that are found on surfaces such as the tiles around a swimming pool or changing rooms. It is not clear why some people get infected and others do not. The time between exposure to the virus and a wart developing (the incubation period) is thought to be 1-6 months.
The bottom line is that you can’t do much prevent yourself getting simple warts.
