Correct, even in that highly improbable circumstance. EWH
Thank you. Just to confirm - even if someone did in fact cut their foot minutes before I did on the glass, there would still be no risk because the virus would have died upon exposure to air?
Welcome back to our Forum. Your current question is rather similar to the one you asked of me in April and suggests a misunderstanding of how HIV is transmitted from person to person. HIV in adults is transmitted only through sexual contact (genital, rector or, on very rare occasions through receiving oral sex) or injection of infected material direct, deep into tissue. As I said in April "...Third, and most importantly, even if it was blood from a person with HIV, HIV is not transmitted with this sort of surface contact....).
In the circumstance that you describe, there is no meaningful risk for HIV. It is unlikely that someone else had cut themselves on the glass before you did, the virus does not live outside the body and becomes non-infectious almost immediately on exposure to the air and environmental temperatures, and HIV is not transmitted on solid surfaces like a piece of glass (the virus may live slightly longer when inside of a hollow object like the inside of a needle).
I would not worry about HIV or hepatitis from this exposure. There is no need for concern or for testing. I hope my comments are helpful and reassuring. EWH
