Hi there,Thank you for your inquiry. From what we gather from the question, you were asking about the possibility of HIV transmission through using a lancet for glucose monitoring and accidentally pricking another person seconds after use. From the information given, this scenario is determined to be Negligible Risk (there is no evidence or no documented cases of transmission. However, there is a theoretical possibility of transmission under certain extenuating circumstances).
The scenario mentioned above does not meet the three components of the HIV Transmission Equation (see down below).
Even if there had been blood containing HIV positive particles on the lancet, the HIV particles would be inactivated as exposure of the virus to oxygen quickly deactivates it. The CDC has shown that "HIV does not survive long outside the body (such on surfaces), and it cannot reproduce outside of the human host" (1). When HIV is exposed to oxygen, it undergoes a rapid decrease in concentration (90-99% within a couple of hours), so the risk of environmental transmission of HIV is essentially zero (1).
Therefore, in the event that the lancet did come in contact with HIV positive blood, the exposure to oxygen, coupled with the fact that there was no direct access to the bloodstream, means there is Negligible Risk of transmission from this activity. Therefore, this scenario does not meet the three components of the HIV Transmission Equation (see down below).
Recommendation: There are no evidence or no documented cases of transmission. Refer to a healthcare professional for more personalized answers
