How to get rid of finger warts and what is the cause?

Wart viruses: Warts are caused by a range of viruses, with each type of virus favoring a certain area for infection. For ex., warts on the fingers like to grow there, rather than say warts that grow in the genital tract. There are ablative therapies u can do at home or with a dermatologist's help (freezing, salicylic acid). I like occlusive therapy: elastic part of bandaid (not white part) covers wart til gone.
