Therefore, I would ALWAYS advise that you wait until at least 5/7 days AFTER it has fully healed and gone before considering yourself no longer infectious. Also, if you get the slightest idea that a cold sore is on it's way then refrain from ANY skin to skin contact with the infected area. The herpes virus will invade the body through the most miniscule of tears in the skin.
Hope this helps.
