I know that herpes can still be transmitted to someone else even if your not having an outbreak but is the same true for genital warts? Also if they are treated, frozen off or whatever they still come back right?
Pretty much, yes. If you have active warts then the chances are much higher that you can spread them.
If they are treated and the virus is killed then they will not come back. The problem is that there may be spots that are infected but not active. If you agressively treat them then there is a good chance that they will not come back.
