I purchased a soda this afternoon, and after I drank it, it occurred to me that perhaps someone took a sip and put it back into the freezer. I remember the answer you gave back in November 2015 about a somewhat similar incident and felt good about it, but then I saw that you guys have revised your statement that HIV dies when exposed to air, and now you're stating that it begins to break down when exposed to air. I also saw that you stated that even though it is breaking down and not dead, that since it's exposed to air it cannot transmit outside of the body. Would that apply to the incident I had this afternoon with the soda bottle? I have 9 cavities that need to be filled over the next few months, so since there are holes in my teeth, would that affect the chances of HIV transmission? Thank you for reading this.

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 from a used drink. We're happy to answer your question for you.

This is a no risk situation. To understand why, know that HIV is a very fragile virus that is rendered intransmissible on exposure to air. In your case, it is worthwhile to check out our transmission equation to get a better sense of what is required for transmission to occur:
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 known to be involved in transfer, an activity known to be involved in transfer, and direct access to the bloodstream. Your situation involves none of these things. Saliva is not a fluid known to be involved in transfer, consuming a fluid potentially containing the virus is not an activity known to be involved in transfer, nor is there direct access to the bloodstream whatsoever. Having cavities does not increase the risk at all.

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