if two people with cold sores on lips give a close mouth kiss than is it possible to transmitt HIV if one them is positive.

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 during an encounter. We're happy to answer your question for you.

Kissing in general is considered a no risk activity, meaning HIV does not transmit this way. To get a better sense of what is required for the virus to transmit, we encourage you to check out our 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 known to be involved in transfer, an activity known to be involved in transfer, and direct access to the bloodstream. Theoretically, if your partner was bleeding from the mouth and you also had a major wound in your mouth (the kind you might have after major dental surgery), there might be some risk. It doesn't sound like this is the case (cold sores do not increase the risk of transfer in this case), so this is no risk.


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