I was drinking soda tonight and I noticed dried food stains on my drinking cup. Is HIV transmission possible? Or is it not possible since it was exposed to air? Thank you.

Hi there, and thanks a lot for contacting the AIDS Vancouver Helpline for your HIV/AIDS related health information. It seems you're concerned about the possibility of HIV transmitting. We're happy to answer your question for you.

This is a no risk situation. To understand why, know that HIV is a a very fragile virus that is rendered intransmissible on exposure to air. Any virus potentially on that cup would not be able to be transmitted to you. Also consider the transmission equation:
HIV TRANSMISSION EQUATION


BODY FLUID
+
ACTIVITY
+
DIRECT ACCESS TO BLOODSTREAM
---------- -------- ----------------------------
• blood (including menstrual) • unprotected anal or vaginal intercourse • vagina
• semen • sharing needles • anus
• pre-cum • mother to child (in specific cases) • urethra in the penis
• rectal secretions • open cuts and sores (in theory)
• vaginal fluids • other mucosal membranes
• breast milk • points of needle injection
You'll see that required for transfer are all of a fluid involved in transfer, an activity involved in transfer, and direct access to the bloodstream. This does not involve an activity involved in transfer, nor does it provide direct access to the bloodstream to any significant extent. For these reasons, this is a no risk situation.

Thanks a lot for contacting the AIDS Vancouver Helpline with your question, we hope it has been answered fully.
