[Question #6600] Unprotected sex for 3 seconds

14 months ago
Hello doctors, 
I became fearful after I remember I had unprotected sex for three seconds. My questions are as follow:
Given that the person I had sex was an immigrant from Africa I decided to do hiv-2 test
1)is the hiv-2 pcr test’s window period the same as hiv-1 pcr test? If yes, what is it? Doctor hook said 12 days for hiv-1 pcr
2)when does hiv-2 pcr become nearly conclusive, and how conclusive is it in terms of percentage?
3)are there any differences between hiv-2 and hiv-1 by pcr tests?
4)they told me the test is above 99% sensitive. Does that mean it is more than 99% accurate?
5) what is the difference between qualitative and quantitative and which one will give more accuracy in terms of results, and do qualititaive and quantitative differ in terms of window period?

Another question very important question: does it take more time for a large amount of semen to become inactive in esxposure to air compared to a very smaller one? It’s really important doctors

When I say large, I’m talking about a considerably larger one

Welcome back to the Forum although I must say I'm disappointed that you found the need.  I cannot help but wonder if this series of questions is related to the questions you asked yesterday.  On some occasions our clients misrepresent the nature of their exposures and the origins of their concerns.  This is turn hinders our ability to provide useful answers. 

In addition, these questions have been already answered.  As I told you 24 hours ago, mutual masturbation is a NO RISK event.  The interval between genital secretions leaving a partner's body and contact with another person are totally irrelevant.  Similarly, the quantity of secretions which you might have come into contact with - small, medium or large- is irrelevant to risk- it is still a no risk event.  No one has EVER been infected through exposure to infected genital secretions occurring in the context of mutual masturbation.

In response to your additional questions:

1)is the hiv-2 pcr test’s window period the same as hiv-1 pcr test? If yes, what is it? Doctor hook said 12 days for hiv-1 pcr
You  are misquoting me.  The range of positivity for HIV-1 to become positive following acquisition of exposure is 9-12 days.  12 day visits are conclusive.

2)when does hiv-2 pcr become nearly conclusive, and how conclusive is it in terms of percentage?
Data on the performance of the HIV-2 PCR are limited because the infection is vanishingly rare so no specific data are available as to test performance.  There are fewer than 50 cases of HIV-2 diagnosed in the U.S. each year.  Typically HIV-2 is diagnosed using the antibody test. 

3)are there any differences between hiv-2 and hiv-1 by pcr tests?
See comment above.  There is vast experience with HIV-1 PCR-type tests and almost none with HIV.  HIV-1 PCR tests are highly reliable.

4)they told me the test is above 99% sensitive. Does that mean it is more than 99% accurate?
99% sensitive means that it would detect 99% of infections.  Actually the sensitivity of current tests for HIV are more than 99% accurate. Results should be believed.

5) what is the difference between qualitative and quantitative and which one will give more accuracy in terms of results, and do qualititaive and quantitative differ in terms of window period?
The quantitative tests for HIV are used for following the impact of therapy on the infection.  For purposes of diagnosis, qualitative and quantitative tests can be considered as equivalent.

Finally, have been down this route before, we do not permit repetitive, anxiety driven questions.  Please do not repeat your questions.  If some part of my response is not clear, please clearly state the question or point that you want clarified.  EWH

Thank you for your answer doctor Hook. Just to confirm, please, if you may, answer question number 3.
1), Doctor, would you tell me why you think HIV becomes ineffective in 30 seconds? Is it because of the small amount (semen on toilet seat) or is it because of the room temperature?  This is a very important question. 
Second, 2)is it not theoretically possible that I would be infected with hiv if the semen touched the tip of my penis (it would eventually go down the urethra)?
And 3) can you be a 100% certain, not 99% but a 100% that some semen on toilet seat will be inactive in 30 seconds or more? Some sites say that hiv can be active for minutes. Why isn’t this true in my case? 


Many thanks doctor!!

READ THIS REPLY VERY QUICKLY.  IF YOU STILL HAVE QUESTIONS, PLEASE RETURN TO YOUR EQARLIER POST!

1. Your follow-up is repetitive and you are going down the same "rabbit hole' you were in yesterday.  AS I SAID BEFORE, HIV becomes non-infectious upon exposure to the environment outside of the body.  The environment has many characteristics including temperature, lower humidity, indirect contact, etc.  this is the only answer I am going to provide.  If you repeat the question, the thread will be closed. Further, if I close the thread again because of these sorts on inconsequential, repetitive, anxiety-driven questions, future questions may be administratively closed without a reply and without return of your posting fee.

2. Repetitive again.  Already answered.  NO!  No one has ever been infected through the sort of contact with genital secretions on an inanimate object of the sort you describe.  Not ever.  You will not be the first.

3.  Repetitive, already answered.  Please review our previous interaction.

Thank you for the answer doc. Would you just please explain why it is not theoretically possible for semen with hiv coming into e tip of my penis to infect me with hiv? I know that sex can lead to hiv, so what is the difference between sex and having semen on the tip of the penis. Please forgive me as I’m really not educated on hiv at all. So why wouldn’t the semen go down to the urethra?
Many thanks doctor

The observation is based on observations of thousand, if not millions of patients who have had millions of cases. 

In fact, I suppose it is theoretically possible that you will be struck by a meteorite falling from the sky while reading my reply HOWEVER it is most unlikely to occur.  Based on the observations of thousands of highly trained scientists who have studied thousands and thousand of cases however it has NEVER been observed and thus, if anything is less likely to occur that you are to be struck by a falling meteor.  Put another way, there is no plausibility to the concerns you have expressed. 

this is my final reply to this series of questions. You have been worried that further repetitive questions may be closed without a response.   I hope that the information I have provided will be helpful to you and allow you to move forward from what appears to be an irrational and unfounded fear.  Please do not continue to worry.  End of thread.  EWH

Final reply.  While it may be theoretically possible for a person to become infected in the manner you describe, the observation by highly trained scientists is that persons do not become infected with HIV in this way is based on observations of thousands, if not millions of patients who have had millions of exposures of this sort..  I provided an analogy regarding being struck by a meteorite from space.  Your risk for getting HIV from the exposure you describe is lower than your risk of being struck by a meteor.

This thread is over.  EWH
