Hello,

Several days ago I went my local gym. To get in you need to enter a pin on a keypad and also press several elevator buttons. When I arrived in the gym, I noticed I had cut my finger and there was fresh blood all over my hand. My question is: is there a possible risk of transmission from entering the pin on the keypad and pushing the elevator buttons using the same hand that had blood all over it?

Hello there,

Thank you for your inquiry. From what we gather from the question, you were asking about the possibility of HIV transmission from having an open wound and getting into contact of a contaminated surface (possibly with the HIV). From the information given, this scenario is determined to be No Risk (transmission of HIV is not possible with the given scenario (No exchange of bodily fluids)).

This scenario does not provide a risk for HIV transmission. This is because it does not satisfy the 3 components of our [HIV Transmission Equation](https://www.aidswindsor.org/healthy-me/hiv-transmission/). The equation requires the following to be present in order for HIV transmission to occur: HIV positive bodily fluid (semen, pre-cum, vaginal fluid, anal fluid, blood, and breast milk), with direct access to the bloodstream, through a High Risk, Low Risk, or Negligible Risk activity.

Further, HIV does not survive long outside the body. However, the virus can survive over 40 days in a completely sealed environment (i.e syringe) [1]. If one is penetrated with a syringe that contains the HIV virus there is a 0 to 2.3% chance that transmission will occur [1].

Recommendation: There is no evidence or no documented cases of transmission. Refer to a healthcare professional for more personalized answers.

Thank you for contacting AIDS Vancouver Helpline,

AIDS Vancouver Helpline, Joseph
