Hello,

I have a question about HIV transmition.

1. I read here on your website, when talking about sores and cuts, you say "deep sores/ cuts". How exactly deep does a sore have to be in order to transmit the HIV virus?

2. I also read about "direct access to the bloodstream". What do you really mean by direct access and blood stream?

QUESTION:
If i'm biting myself on a lip or cheeck, and then I develop a sore and the sore is bleeding, is the bleeding sore which I bite myself a direct access to the blood stream? Does biting myself on a lip or cheeck till I bleed a direct access?

I understand HIV dies when exposed to oxygen/ air, but I have a question that is bothering me!
My friend had a bleeding sore on his toe because he kicked a stone and got injured and started to bleed. Then he touched his sore on removing the damaged skin. Immediately, he touched my clothes with blood on his hands, then blood remained. I immediately touched the place on my clothes at which he touched me, which had blood. Then I touched my head. Then I washed my head with water. Then water started to flow into my mouth, directly to the bleeding sore on my lip.

Assuming my friend is HIV , am I at risk, or did I contract the virus? Do I need to get tested?

Please help!

Hello and thanks for contacting AIDS Vancouver with your question.

It seems you are concerned about HIV infection after touching your friend's blood. We are glad to provide some information.

For HIV to transmit through a wound the wound has to be so deep that it requires stitches and it has to be exposed to a lot of blood. This does not seem to be the case in the scenario you described. In the activity that you described there is no risk involved and we therefore do not recommend testing specifically for this exposure.

The following transmission equation shows you what we mean by direct access.
