Welcome to the Forum. I considered not answering your question as you failed to respect the 2000 character limit placed on questions but instead will provide some brief comments.
Your partner, a transgender CSW, was a high risk partner but the fact that she had recent HIV testing which was negative transforms this into a low risk event. She had done what was needed to avoid HIV up until at least 3 months before her last test and would have to be quite unlikely to have acquired HIV in the brief interval since her last test.
While you are correct that had she been in the process of sero-converting for HIV she might have been somewhat more infectious on average than if she had an established infection, as explained above, nonetheless this was a low risk event. I would not worry and I certainly would not have recommended PEP in this situation
At this time, three weeks after exposure, a combined HIV p24 antigen/HIV antibody test will provide you with definitive results as to whether or not your recent symptoms were due to HIV- I doubt that they were. If you will wait until day 28 after your exposure, results of the combination test will be definitive.
I I hope these comments are helpful to you. EWH
Just as an additional note to the above, about 6 days following this potential exposure I experienced what I assumed to be traveler's diarrhea (diarrhea and a fairly high 38.something fever), which cleared up after 3 or 4 days.
And I have now, 3 weeks after this potential exposure, contracted what I assume to be a common cold (sore throat, runny nose, cough, slightly inflamed glands).
I'm guessing a lot of this is down to stress and my previous gastro condition, and is not indicative of ARS (this would certainly seem to be the case, from what I've gleaned from this forum), but I include it here just so you have all the information.
I have recently found a clinic which offers the HIV P24 Ag + Ab test, and I am considering booking an appointment. Would you recommend this, given my situation?
Ah, I'm very sorry for breaching the forum rules. I just didn't think when posting that follow-up information—silly of me. Thanks very much for still taking the time to reply despite this, and for putting my mind at ease.
I will wait until 28 days and get the combined HIV p24 antigen/HIV antibody test done, then. From looking at your response, it seems like I should probably expect the result to be negative, yes? I do hope so. Thanks again.
Correct, I anticipate your test at 298 days will be negative. Take care. EWH
As you anticipated, my 28-day combo test was negative. Should I regard this result as definitive, or would you still recommend a 3-month test as well?
Thanks again for your help.
I see no reason for testing at 3 months. EWH
