Dear Sir/Madam

I’m writing to ask some few questions, last week we were cleaning glue from a peace of timber with a knife. Somebody was cleaning it before me using that knife; after he cleaned his piece of timber i got his knife and started cleaning mine. Between the events of cleaning the timber i cut my hand, it was not big and also not bleeding because I was rubbing it; I asked him if the knife also cut his hand and he said yes.

Can HIV be transmitted through this way?

I didn’t see any blood on the knife but If he wiped off the blood from the knife can HIV still be present on the surface?

I’m afraid if he had HIV i would get it by the cut wound

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 the knife 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.
