Hi there, and thanks for contacting the AIDS Vancouver Helpline with your question. It seems you're concerned about the possibility of HIV transmitting through contact with some bloody gauze. We're happy to answer your question for you.

This is a no risk situation. To understand why, check out our transmission equation. It will help you get a better sense of what is required for HIV 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 can see in the chart that required for transfer are a bodily fluid known to be involved in transfer, an activity involved in transfer, and direct access to the bloodstream. Simply touching a blood gauze does not provide 2/3 of the required components for transmission to occur (an activity involved in transfer and direct access to the bloodstream). It's important to also consider that HIV does not survive well outside of the body. For this reason, direct access to the bloodstream is required (without exposure to the environment.

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