Many thanks for your reply and the information provided. I feel I have peace of mind now.
Hello,
Apologies for the delay in replying to your post.
Your sexual encounter can be considered low risk, even if she was HIV positive. To confirm that, you had a negative HIV Duo of 4th generation after 7 weeks, which is fully conclusive. HIV-2 is extremely rare, as it is less aggressive than HIV-1, and I doubt very much that you could have been infected under these circumstances. In fact HIV-2 antibodies would have been detectable at 7 weeks anyway. In summary I can assure you that you have not been infected with HIV and that you do not really need to have any further tests.
Myalgia in isolation is not a symptom of acute HIV sero-conversion, and stress can certainly be a contributory factor.
Best wishes,
Dr José
Sorry but one last question ? Would you consider a low risk exposure ( oral sex ) and a -ve 4th gen 28 days test as a conclusive result ? Again I know you are busyso apologies in advance .
