Let's rephrase: "If I was exposed to HIV through sex with an HIV-positive person, then had sex with an HIV-negative person 2 hours later, could I have transmitted HIV to the second person even though I tested negative 6 months later?"
If you tested HIV-negative after 6 months, and had no other exposures during that time, you did not contract HIV from the first encounter. Since you didn't become HIV-positive, you could not have transmitted HIV to the second person. However, this situation highlights the importance of using protection during sexual encounters and getting tested at appropriate intervals. For most accurate results, testing should be done:
• 10-33 days after exposure for NAT tests
• 18-45 days for blood draw antigen/antibody tests
• 18-90 days for rapid finger stick tests
• 23-90 days for antibody tests
Each sexual partner should get their own HIV test for confirmation of their status.
