Hi there,Thank you for your inquiry. From what we gather from the question, you were asking about the possibility of HIV transmission through pricking your finger with a yarning needle. From the information given, this scenario is determined to be No Risk (transmission of HIV is not possible in the given scenario).
The scenario mentioned above does not meet the three components of the HIV Transmission Equation (see down below).
You did not mention whether you noticed any dried fluids on the yarning needle, but even if there was, the yarning needle would not contain any active HIV particles because 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 needle did come in contact with bodily fluid, the exposure to oxygen, coupled with the fact that there was no direct access to the bloodstream, means there is No Risk of transmission from this activity.
Recommendation: No need for an HIV test with the scenario provided, please refer to a healthcare professional for other health related questions.
