Thumb poked with scalpel

Question: 

Hello,

At work I was using a scalpel and felt a sharp poke on my dorsal thumb, I was wearing sterile gloves on top of regular gloves (two barriers before skin). I immediately checked to see if my gloves were broken and if I was bleeding. Filling both gloves with water, there was no leak in either glove. I was not bleeding at all, and putting rubbing alcohol on my skin did not cause irritation, so I do not think my skin was broken. Patient was extremely low risk for HIV. Most of my colleagues told me that it was not an exposure, should I be worried?

Answer: 

Hello,

Thank you for your inquiry. From what we gather from the question, you were asking about acquiring HIV through a scalpel poke. 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 transmission equation. It does not satisfy the equation because HIV is rendered inactive when exposed to oxygen and the activity does not provide direct access to the bloodstream.

No need for HIV test with the scenario provided, refer to a physician for other health related questions
