Mandi, It is not known at this date if the virus remains in someone for decades dormant, (and if so where) or people just get re-infected over and over again from repeated exposure to it because it is so ubiquitous in our world. I spent a great deal of time with Dr. Gillison on the phone today reviewing what we do NOT know, as OCF is funding a very preliminary look at some of this with her. Given all that we do not know for sure, you would be wrong to beat yourself up for something that there is no way of knowing if it is even possible.
