Welcome back, but sorry you found it necessary, especially given the replies in your three recent threads a month ago. For the most part, these quesitons are repeats of ones already asked and answered.
1) It has been proved you do not have HIV, so questions about symptoms related to HIV are irrelevant. HIV test results always overrule both symptoms and exposure history. Anyway, yeast infections are never valid indicators of new HIV infection. Yeast can be a problem in longstanding HIV (overt AIDS); even then, it almost never is the main or only symptom indicating HIV.
2) BV is not a sign of HIV.
3) Yeast and BV often coexist. This is irrelevant to your concerns about both HIV and HSV1.
4-7) The index values on HSV testing are widely variable and do not primarily reflect the amount of HSV antibody present. If the value if over the positive cut-off, it's positive; below is negative, and that's all that can be said. If someone is tested at say weekly intervals in the weeks after catching HSV (either HSV1 or HSV2), there can be a trend from lower to higher numbers, but even this often doesn't happen. The very same blood specimen, tested 10 times in the same laboratory (with different lots of test kits) will give 10 different numbers which can vary from just over the cut-off index to high above it. Therefore, height of the index value cannot be used to conclude how long someone might have been infected. Your and your partner's different values say absolutely nothing about how long either of you has been infected or who was infected first.
8) There are no HIV strains not detected by the duo test. Your test results are conclusive.
Given your herpes concerns, I'll add that HSV1 does not increase the risk of HIV if sexually exposed. Only HSV2 does that, according to numerous research studies.
Please note the forum does not permit repeated questions on the same topic or exposure. This being your fourth about this exposure, HIV, and HSV, it will have to be your last; future new questions along these lines will receive no reply and the posting fee will not be refunded. This policy is based on compassion, not criticism, and is intended to reduce temptations to keep paying for questions with obvious answers. In addition, experience shows that continued answers tend to prolong users' anxieties rather than reducing them. Finally, such questions have little educational value for other users, one of the forum's main purposes. Thanks for your understanding.
