It could be a new strain, or the same strain could have reactivated and come out of dormancy. There is no way to know for sure without having done strain specific testing back in 06 and 07. Hpv can be cleared much sooner if the individual pays a lot of attention to their immune system. As always, I recommend to everyone to read Janet Maccaro's 90 Day Immune System Makeover. It teaches you how to eat for your immune system.
Hi, if a strain reactivates and comes out of dormancy, does that mean you will never clear that strain?
No, that's not what it means at all. It just means that for some reason, the strain has reactivated making the individual contagious again with or without causing symptoms. This may happen as a result of a weakened immune system. Working on the immune system and adopting healthier lifestyle changes is an excellent way to push the virus into dormancy- and keep it there for good.
