Warts are contagious, but most only pose a very low risk of being passed to another person through direct or indirect contact. However, genital warts are considerably more contagious than most other types of warts.
Most warts pose no significant health risks and will disappear within a year or two of first appearing. However, because warts can be unsightly – and in the case of genital warts, may pose significant health risks – some patients may choose to treat them with medications or chemicals, or to have them surgically removed. However, it is not uncommon for warts to recur even after they’ve been treated effectively.
About warts
Warts are noncancerous skin growths caused by the human papillomavirus (HPV). Types of this virus cause an infection that shows up in the top layer of skin, inside the mouth, on the genitals or in the rectal area. In most cases, warts are pink to flesh–colored and have a rough texture. However, they also can have a dark color and a smooth feel.
There are several different major categories of warts. The type of HPV a person contracts will determine the type of wart that develops. More than 100 HPV viruses have been identified. These viruses stimulate the rapid growth of cells on the outer layer of the skin (epidermis), causing the formation of warts on the skin and mucous membranes.
