Question:

Dear Doc,
I am worried about the possibility of having been infected with HIV.

I was recently told by the woman I have been intimate with that she has HIV. Although, thankfully, we have not had sex of any kind - neither oral nor penetrative - nor shared any needles, we have done a lot of deep kissing i.e. deep in the mouth and a lot of tonguing. What concerns me about this is that I recently went to the dentist and, as a result of dental work, have a 'wound' in my gums between my teeth which is not completely healed. Moreover, my girlfriend had a sore on her chin for a while, which although seemingly healed, i.e. dry and with a scab, may potentially still have been wet or not completely healed. We kissed in the way described above while I had this small 'wound' in my mouth from the dental work and during the kissing I repeatedly licked her face, including the sore on her chin.

She informed me that she is on anti-viral drugs and that recent tests have shown that the viral levels in her blood are extremely low (although of course still in her system).

My question is: how great is the risk that I have contracted HIV through the activities described above? Should I ask her whether she has/had any wounds in her mouth during the period that we kissed?

Many thanks for your time and I anxiously await your answer.

Transmission of HIV in any kind of normal circumstance does not occur. A few years ago, a case was described, but both partners apparently were homeless, with really, really bad dental health, with missing teeth, and lots of open, oozing sores in each person's mouth.

The wound on the chin wouldn't seem to be a big risk, and your dental wound is small. The fact that she's on therapy for HIV also should minimize the risk.

As you did have a wound in your mouth, I can't say the risk of transmission is zero, although my guess is that transmission in this setting is extremely unlikely. For your own piece of mind, I strongly suggest that you be tested for HIV. You'll sleep better.

I'm glad you two had this discussion before having sexual relations. It says something about her responsibility and feelings for you. It's normal for you to have these questions, too. Bottom line is that safer sex practices work.
