OK, now things are clearer. Thank you. You are thinking about this incorrectly. If you have genital HSV 2, it does not come up through your body and out through your mouth. Nor does the reverse happen. While it is possible that you contracted HSV 2 orally and genitally at the same time (gave oral sex to and had intercourse with the same person at the same encounter), that is not common. And if you happened to have had that happen, HSV 2 orally recurs infrequently and sheds very infrequently. The likelihood that all of these things happened to you at the same time, combined with your daughter contracting HSV 2 from an inanimate object is just astronomically small! I think the odds are close to one in a million that all of that would happen at the same time.
Since you know that you have HSV 1 infection as well as HSV 2, my best guess would be if these sensations are caused by herpes, it is HSV 1, not HSV 2.
A first time infection with HSV 2 would not last 8 weeks, no. And no, I don’t think a value of 0.15 indicates antibody is slowing developing at all! And please, don’t test her again. The test is not good for people her age and could give a false positive and totally freak both of you out.
From the antibody test, it does appear that you daughter likely has HSV 1, the cold sore virus. This may cause her to have cold sores at some point in the future. but your concern about her having HSV 2 orally is, well, way way off. I don’t know how else to put it.
