Hello,

My friend has HIV and has a count of below 20/ml. I took a sip out of his herbal iced tea today without thinking and am slightly concerned. I drank out of a straw and it was brief, but it was his straw. I have periodontal disease. His mouth is in perfect condition. Is there any risk?

Hi there!
Thanks for contacting the AIDS Vancouver helpline with your HIV related questions and concerns. We are happy to help!

Regarding the situation you just described, regardless of their viral count, this would be No Risk. In order to transmit HIV through saliva, you would have to drink apprx 9L of the persons saliva... AKA, Impossible! This is due to an enzyme found in saliva that breaks down viruses and bacteria.

I am attaching the HIV transmission equation here, which makes it easier to see exactly what components are required for there to be a risk of acquiring HIV:

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
Hopefully this helped!

Sincerely,
Christina
