Risk evaluation

Hi experts,

I am currently waiting on a result after having unprotected vaginal sex  with a Thai sex worker (3.5 years ago).

My anxiety is through the roof.

I have been trying to relieve some of my anxiety by researching, the info on this website has been very helpful.

According to a study referenced on wikipedia - the risk of female to male transmission is 0.04% per act, with the risk increasing up to 10 fold in low income countries. In addition, circumcision may also provide some additional protection (approx. 50%) - though i am not sure how to apply this reduction as the 0.04% stat is probably inclusive circumcised and non-circumcised.

I believe my thai exposure to be 0.4% * risk that sex worker had HIV (10%??)

I cannot find any statistics (i.e. estimated transmission rates) on the following:

1. anal sex (not receiving) - I am also nervous about an encounter i had around 9-10 years ago.
2. asymptomatic stage i.e. i know hiv can be asymptomatic for 20 + years, but what is the norm...

Any info on these questions would be much appreciated.

Thank you all for the great website.

The ONLY way to know your status is to test, which you are doing so good for you! Chances are your one-time exposure, even if she did have HIV, did not lead to infection. Although it can happen, one-time exposures usually don't cause infection. Try to relax and stay calm until you get your results. Weighing the "statistics" does you know good in this situation and you will only drive yourself crazy. Just hang in there!

Sorry Teak, I thank you for reading my post, let me explain what has occurred.

As stated in my previous post, my partner was tested several weeks ago for HIV. Last week, she again met with her mid-wife and asked about the HIV results - it turns out the blood test had not been signed-off and they had not tested it. This is the second test they've screwed up (the other was not HIV test), my then partner refused a second test, the hospital said they'd take it during her next blood count test. Scheduled in around 10 days time.

I was not completley honest with "waiting on result" - i am booked in for test this afternoon.

In the interim, my mind has been going over all of my sexual history in attempt to evaluate my risk. I have had a lot of unprotected female/male sex - though, this has been with a low risk population.

I do however have vague memories of a very drunk (anal giving) encounter around 9-10 years ago, possibly unprotected - hence my request for any additional info in regards to these two statistics.

I have been very careless in not getting myself tested earlier! what has triggered my anxiety was a message left on my partners phone from pathology i.e. there was something wrong with a test - turns out there was nothing wrong in the sense they'd found something, rather they had written the incorrect date of birth on it. So it was not useable - nor was this,  the HIV test.

Any info on the requested stats, greatly appreciated.
