[Question #5089] HIV/STD Vaginal Fluid Hand to Mouth

23 months ago
Good day.   I fingered/masturbated a girl I have known for a couple of months getting her vaginal fluids on my hands.  I also took my hand from her vagina with her vaginal fluids on them directly to my mouth in a period of about 5 seconds.   The main clarification I am asking for is the hand with the vaginal fluid on it into my mouth.  I think I know the answer but just wanted to see what the risk of HIV or other STD's might be in this scenario.   I should have asked this question as clarification to my earlier question but simply forgot and would like to know for future reference.   Thanks for your help.

Welcome back to the forum. But I'm sorry you found it necessary. In quick review of your several other questions, mostly you have asked about obvious low risk events. The fact is that sexual transmission of HIV almost never occurs without direct, insertive sex. That is, if an unprotected penis (no condom) does not enter a partner's vagina, rectum or (rarely) mouth, there is no realistic chance of HIV transmission. Even with unprotected intercourse, lasting several minutes, with ejaculation, the transmission risk if one partner has HIV averages once for every several hundred events (for the receptive partner in anal sex) to as low as 1 chance in 2,500 for the penile partner in vaginal or anal sex. Given these data, what could the risk be from the indirect sorts of exposure you have been asking about?

As for oral contact with vaginal fluids, there has never been a reported, scientifically documented case of HIV transmission by cunnilingus (oral-vaginal sex). So logically the risk also is nil from oral exposure to vaginal fluids on fingers. This is one of the reasons that fingering and hand-genital contact are considered entirely safe, even with the most unsafe partners.

I hope this helps clarify things.  Best wishes--  HHH, MD

Dr. Handsfield,

Thanks for your reply.  So never say never but very low risk the receipt of oral from my original question and the vaginal fluid to mouth scenario described more recently above.  Just to clear my head of this I will probably test with antibody/antigen combo and RNA at 28 days.  Is that still sufficient for a definitive result?  In the past it has always cleared my head of the event and I'm able to move on.

I agree that anxious persons often are more reassured by a negative test result than by professional opinion, no matter how expert. So feel free to be tested. But you need to wait until 6 weeks to get a conclusive AgAb test result. (You can find lots of discussions on this forum about our change from 4 to 6 weeks, about a year ago.)---

Dr. Handsfield.

I need to wait 6 weeks even if I combine the  AgAb test with an RNA?  I thought the combo/duo test with the RNA test would allow a conclusive result a couple of weeks earlier.  Again thanks.

I missed that you're thinking of an RNA test as well. You're right:  the combination of RNA at 2-4 weeks plus either an AgAb or 3rd generation antibody test at 4 weeks is considered 100% conclusive. But I consider the RNA test in such a situation an unfortunate waste of money! The chance you caught HIV is well under one in several million. Is it really worth a couple hundred dollars for such a test?

That concludes the two follow-up comments and replies included with each question and so ends this thread. I hope the discussion has been helpful.
