Depends on location: Warts are caused by viruses. Sometimes a person has something she calls a wart, but may not be a viral wart. In those cases, the wart-like thing might not be a real wart. Common warts (not on the genitals) don't have a know prevention method. Genital warts can be prevented by the HPV vaccine, which prevents some (not all) of the viruses that cause genital warts. All teens should be vaccinated.
