Risk of hiv from sharp objects

Question: 

I know hiv can be spread through needles, but what about sharp objects?
today I got a steel wire stab in my hand and bleed, if that iron has just stabbed into another person and got bloody then I am at risk for hiv or not, do I need to drink PEP?
Thanks you so much

Answer: 

Hello there.

Thank you for your inquiry. From what we gather from the question, you were asking about the possibility of HIV transmission from being punctured by sharp object (i.e. barb wire) contaminated with HIV positive blood. 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 of transmission. This is because it does not satisfy the 3 components of our HIV Transmission Equation. 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.
