Dear Mr/Ms,

Yesterday, I received oral sex from my gay friend (with HIV positive status), during that I released sperm on his mouth. He has been taking ARV drugs and HIV is below detection threshold. So Is there any HIV risk for me from this action? Will I need a test for this particular situation?

Thanks in advanced for your support!

Thank you for your inquiry. From what we gather from the question, you were asking about acquiring HIV from receiving oral sex. From the information given, this scenario is determined to be Negligible Risk (There are no evidence or no documented cases of transmission).

The scenario mentioned above does meet the three components of the transmission equation. There is a risk present for potential HIV transmission because the scenario does involve the exchange of body fluids (1). However, there has never been a confirmed report of this scenario (1). The transmission equation requires the exchange of HIV positive bodily fluid to come into contact with a HIV negative individual through a high risk activity that has direct access to the bloodstream. In this scenario bodily fluid could technically be exchanged between persons, but consider that saliva does not contain enough of the HIV virus to be infected (2). Bodily fluids that carry the HIV virus include: blood, semen (including pre-ejaculate), vaginal fluids, breast milk, and rectal secretion (1). High risk activity includes: condom less sex, sharing needles, unsafe tattoos or piercings, vertical transmission–from mother to child (in utero, during delivery, breastfeeding) (1). This scenario is not considered to be a high risk activity. Direct access to enter the bloodstream is via: vagina, anus, urethra in the penis, open cuts and sores (in theory), other mucosal membranes, and points of needle injection (1). In this scenario the equation is satisfied, but there has been no confirmed reports (1).

Recommendation: There are no evidence or no documented cases of transmission refer to Physician for more personalized answers.
