Hello, I was riding the bus when suddenly I looked at the back of my shirt and saw that a pimple popped. Is there a risk of the virus getting through my shirt since the blood from my pimple went through my shirt?
Hi there and thank you for reaching out to AIDS Vancouver with your questions. We're happy to help!
To start off with: the scenario that you described is a no risk situation. 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 superficial wound (i.e. a pimple) like the one described in your question does not provide direct access to the bloodstream.
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.
