Warts are caused by a virus.
Warts are caused by a virus. They are contagious. A variety of treatments are available. Treatments include freezing warts with liquid nitrogen. Various acids, blistering agents, or caustic chemicals can be applied to the surface of the wart with little or no discomfort. Laser therapy is also effective in the treatment of warts.
Various therapies are available for the eradication of warts. However, multiple treatments may be necessary to completely eradicate warts. If the virus has not been totally eradicated from the skin, warts may recur, often months later. Remember, patience and persistence will pay off in wart treatment.
