How long after exposure did you test?
Yes this is called asymptomatic viral shedding. It happens with both hsv1 and hsv2, and it happens where ever you have it (like oral hsv1 or genital hsv1, etc.).
HSV 2 genital 15-30% of days evaluated
HSV 1 genital 3-5% of days evaluated
HSV 1 oral 9-18% of days evaluated
HSV 2 oral 1% of days evaluated
Hope this helps.
