There is no place in this discussion for the term “exposed” If an IgG is accurately positive, someone is both infected and potentially infectious to others.
There are a few false positives on the HSV 1 IgG test in the low positive range (below 3.0) but the bigger problem is false negatives.
If you have a partner who also tests positive for HSV 1, and it is oral or location unknown, it is highly unlikely that they would get it in a new location.
And you are likely shedding very little after being infected for two years.
