The actual cryogenic treatment of the warts is just to remove the warts through the low temperature, but it can’t completely remove the potential viral infection of the warts, if the viral infection still exists after the cryogenic treatment, it can still be infected by the direct or indirect contact. In order to minimize the spread of the virus, it is recommended to avoid sharing bathtubs and sexual intercourse (or taking safety measures) during the treatment period, and to follow the doctor’s instructions for follow-up examinations.
