Anxiety

Hello Dr.HHH, I am 25 years old Indian male uncircumcised living in Canada. I had unprotected vaginal sex with a escort a week ago she is 37 years old caucasian, this is my first ever sexual experience  . After the encounter I got so paranoid about hiv and I met her again to ask if she has any diseases, she said she gets tested monthly and there is nothing to worry about and she didn't charge any money for the meeting. But I really don't know whether to trust her or not?What are the chances of transmission of hiv through one exposure? Since I am uncircumcised is there any more risk? What is the best time to get tested?

Yes, it is a good sign. At 6 weeks antibody tests detect over 95% of recent infections.  EWH

Test is only for hiv antibody, but is 6 week negative a good sign?. Thanks.

[Edward W Hook, MD]

If this testing was done with a 4th generation, combination HIV p24 antigen/HIV antobdy test, this is a conclusive result.  If the test was only for HIV antibodies, results are not conclsuive until 8 weeks after exposure.  EWH

Hello Doctor, my 6 week test result came back negative. For one time exposure you and Dr.HHH consider 6 week test as conclusive ,  so should I take it as conclusive? or get tested again after 12 weeks. Thanks.

If she were in the window period she would be, on average more infectious however, for persons to be in the window period is very, very rare.  I urge you not to worry. EWH

Hello Doctor, she contacted me yesterday and told me that all her tests came back negative. But my question if she is in window period am I be at more risk of acquiring hiv?

[Edward W Hook, MD]

No, at 4 days your test results from your urine specimen are completely reliable/  EWH

Thank you doctor for your valuable thoughts, I have given my urine culture test after 4 days of my exposure and they came back negative for chlamydia and gonorrhea. but is 4 days to early to detect chlamydia and gonorrhea?

Welcome to our Forum.  I'll be pleased to comment.  No single sexual exposure places a person at high risk for acquisition of HIV.  The reasons for this are several.  These include:

1.  Most people, including most commercial sex workers do not have HIV.
2.  If she was infected, most exposures to infected partners do not lead to infection.  In fact, only about 1 in 1000-2000 exposures leads to infection, if your partner had infection.
3.  The fact you are uncircumcised does slightly increase your risk for infection but that increase is slight.

Testing is reasonable.  It is unlikely that you will be positive.  Testing with a standard HIV antibody test at 8 weeks will provide definitive results.  I would not worry however.  EWH
