HPV usually enters the body through tiny lesions in your skin. The HPV varieties that cause warts and verrucas can be transmitted both through direct skin-to-skin contact with a person who is infected and through indirect contact via an inanimate object. Genital warts are passed on through sexual contact. Some types of HPV are transferred more easily than others, and children and people who have a weak immune system are more vulnerable to infection than healthy adults.
HPV is very difficult to detect as it has a long incubation period. After you become infected it could take anywhere from two to six months before you notice any wart symptoms. It is not possible to prevent warts completely, but you can minimise your risk of an HPV infection by washing your hands frequently, not walking barefoot in public areas, taking care of your skin and staying healthy to keep your immune system strong.
