Can I get Hiv from someone's blood getting into my mosquito bite?

Question: 

Hi there so here's my story. I was outside with a lot of people camping. They were passing around an afterbite stick for mosquitoes. I needed some and I put it on about 50 of my bites. (I got bit a lot) Am I gonna get hiv from someone's blood maybe getting onto the stick and into my mosquito bites? I don't know if any of them were open, bleeding or not. There was a 5 second delay from me getting the stick from a person and putting it onto my bites. Please help, I'm really anxious about this.

Answer: 

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 above does not constitute any risk for HIV transmission. To help with my explanation, here is a copy of the AIDS Vancouver Transmission Equation that we use to determine whether or not there is a risk for HIV transmission:

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

= RISK OF HIV TRANSMISSION

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 bug bite 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 that this helps ease your anxiety as there is no need to worry! Please feel free to contact us with any further concerns.
