The risk of transmission is irrelevant. The test result shows you weren't infected, so there is no point in speculating about hypothetical risks.
Doctor,
thanks for your answer. I searched the forum and found most ppl have concern that the chance of hiv entering the body via the open sores on the penis. But what about the possibility of hiv transmitted from an open sore on the penis which is not covered by the codom to rectal?
Welcome to the forum.
Relax. your negative test result is 100% reliable. In considering the likelihood someone has HIV, test results ALWAYS overrule exposure history, symptoms, or all other factors -- as long as testing is done sufficiently long after exposure, and 9 weeks is plenty. Although many health agencies recommend 3 months for definitive results, with modern HIV tests virtually everyone with a new HIV infection has positve results by 6-8 weeks.
As for your apparently new HSV-2 infection, the important thing is that your HIV results show you didn't catch HIV. Simultaneous transmission of HIV and HSV-2 clearly can occur, and in such circumstances, the risk of HIV transmission is substantially elevated. But your test results show it didn't happen to you.
Given the common advice for 3 months as the definitive testing interval, perhaps you will feel better if you have one more HIV antibody test at that time. However, this is not "code" to suggest I believe you might have been infected. I do not, and recommend any additional testing solely for its reassurance value. You can expect an additional antibody test to remain negative.
I hope this has helped. Best wishes-- HHH, MD
