I stupidly rubbed coke into someone else’s gums and then I believe afterwards I then did it to myself. What is the risk of transferring their blood into my finger and then rubbing it into my gums and bloodstream. Would this pose a risk of a potential exposure?
Thank you for your inquiry. From what we gather from the question, you are asking about the risk of HIV acquisition through blood from someone else's gums being transferred to your own gums via your finger. From the information given, this scenario is determined to be of low risk (evidence of transmission occurs through these activities when certain conditions are met), as there is potentially direct access to the bloodstream via any lesions or cuts there may have been on the gums.
Recommendation: We would suggest you speak to a physician about being tested for HIV, and speak to them about methods you could use to reduce your risk in the future (eg. PrEP/PEP).
