I was sleeping in the bed with my friend, who is diagnosed and i had fresh grazes on my skin (i fell on the ground and hurt myself). What is the possibility, that if she had some open cuts on her skin, there could be transmission to my body?
Hi there and thank you for reaching out to AIDS Vancouver with your questions. We're happy to help!
The situation that you have described is considered a no risk scenario, because small superficial cuts do not pose a risk for HIV transmission. To help with my explanation, here is a copy of the AIDS Vancouver transmission equation that we use to determine if there is a risk for HIV transmission:
|• 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|
In order for there to be a risk of HIV transmission, all 3 factors (body fluid, activity, and direct access to the bloodstream) must be present. The main thing lacking in your interaction is direct access to the bloodstream. In order for a cut or wound to provide said access, the cut needs to be gushing blood and require immediate and professional medical attention. A small cut like the one described in your question does not provide direct access to the bloodstream.
If you’re interested, here are some great resources to help further your understand about HIV Transmission:
Avert and CATIE are two fantastic and reliable website concerning HIV transmission and testing, and I highly encourage you to take a read through if you have any further questions.
I hope I was able to answer your question, and feel free to contact us with any further concerns.
