mate you have nothing to worry about
Thank you for the advice.
You had a single exposure to a commercial sex worker (CSW). Your chances of having gotten HIV from this exposure are extraordinarily low. Here's why:
1, Chances are, your partner did not have HIV. Most CSWs do not.
2. Your chance of getting HIV, if she was infected is less than one in 1000 per exposure.
3. You have had an HIV test at 5 weeks. After 5 weeks between 85 and 90% of tests that are going to become positive will have.
When you put all of these facts together, your chances of being infected from the exposure you describe is less than one 100th of 1%. If you get retested in the future, you will be a little bit, but not much more sure that you are not infected. If I were you I would take the results I have, forget about your risk of having gotten infected and move on with your life. I would not get further testing. EWH
