That’s a great question and there is no way to know with 100% certainty. However, HSV 1 strongly prefers the oral area over the genital area, so I think if she was infected orally, she would likely recur there. that is more likely than genital recurrences, actually. Given that half the population has HSV 1, 70% don’t know it and the standard test misses 30% of HSV 1 infections compared to the western blot, it is truly a crap shoot when someone says “I don’t have the cold sore virus”. At least, with this person, they know and can do things to reduce transmission to a partner, like taking daily antiviral medicine, as an option
