1) Is it possible, at all, that I am not actually HSV2 positive? If possible, what would potentially cause all the positive tests?
If you are certain that you have the University of Washington herpes westernblot done, and it was positive twice, then you have HSV-2 infection, no question. I would simply suggest that you make sure that it’s not an immunoblot and that the testing was actually done at the University of Washington.
2) Assuming I got HSV2 in 2020, would it make sense that all my tests are this “low” of an index value?
Yes, some people actually just stay at low positive IgG values the entire time they’re infected with HSV-2. That’s why we tell people who test positive in the range of 1.1 to 1.5 that there is and 85% chance that this is a false positive, not 100% chance
3) I have read many, many studies on preventing the transmission of HSV2, but, I struggle with statistics – assuming I have HSV2, and I take daily valtrex, and I have sexual contact every day with my partner, and we are not using condoms, what is the percentage chance she will contract the virus? How much is that reduced if we do use condoms? (all studies I read assume only like 50 sexual acts in a year… I would need to assume 365/year)
Condoms reduce transmission from males to females by 96% when they are used with every intercourse and stay in tact. Antiviral medicine reduces transmission by almost half so when the two are combined transmission is extremely unlikely
4) I have read that HSV2 can be passed orally, but is not common. What is the actual percentage risk of my partner contracting HSV2 orally given regular fellatio, including semen consumption? (no condom)
I’m afraid we do not have those numbers for you
5) If gained orally, would she also then have it genitally? If she had symptoms from oral contraction, would they present the same as HSV1?
If she acquired HSV-2 by giving you oral sex, it would look just like a cold sore, correct. If she only contracted it orally, it would essentially vaccinate her against HSV-2 genital infection
