Hiv risk transition through blood to open sore



I stupidly did coke on the weekend and I don’t use notes or straws as I don’t like sharing with other people. However, I was getting the coke of the plate with my finger and then inserting this into my nose. I noticed half way through there was a bit of blood on the plate (I had a nose bleed previously so potentially mine). If it wasn’t mine - and I dabbed that bit of coke and also some of the blood (someone else’s) and inserted into my nose with my open sore, am I at risk of HIV, I am very nervous and would love some clarity on the situation.

Thank you



Thank you for your inquiry. From what we gather from the question, you were asking about your risk of HIV acquisition from inserting blood into your nose (with an open sore).

From the information given, this scenario is determined to be a Negligible Risk: There are no evidence or no documented cases of transmission. However, there is a theoretical possibility.

HIV is not known to survive long outside the human body (such as on surfaces), and it cannot reproduce outside of a human host (1). However, in this circumstance, you may be at a potential risk depending on the variability of a few factors:

1) The freshness of the blood 2) The quantity that was inserted into your nose

Although it seems as if there is a high possibility that this was your blood (based on your previous nose-bleed), this scenario fits our criteria for HIV Transmission due to the presence of blood with access to the blood stream. Yet, to reiterate, HIV outside of the body is quickly rendered inactive or weakened by the presence of oxygen. In this case, we conclude that while there is no evidence or no documented cases of transmission, there is still a negligible risk of transmission occurring.
